Got back to the garage just in time to have the radiator crack and dump coolant all over the garage floor. :roll: So I'm in the market for a new one. I think the car sat so long w/ old coolant that its corroded from the inside out, a shame really, the radiator was a nice unit.



Well, that's not fun. Any chance Summit has a drop in replacement?

Just ordered. Griffin on the way. I pulled the old one last night and the electric fan had somehow started to make contact with the fins and wore a whole in it. After getting it out, I looked inside. I've seen worse, but I've seen better too. I have a feeling there's a lot of passages gunked up, so a new one it is. I'm not going to ask some poor welder to try and patch that thing. With the other improvements, I think this should cure my cooling problems.

Also picked up an oil catch can. Summit is taking all my money. :roll:
The car did seem to idle better and be more consistent stoplight to stoplight after the carb adjustments. The fuel pressure gauge was sitting at 9psi again (should be 6.5). Even after it got up to temp it's still high. I don't trust the gauge anymore. A few sputters under WOT around 4-5k rpm but then screams way past 6 and wants to keep going. Spinning the whole way. I'm out of town this weekend but I'll put it back together and get the tires on it for some actual fun when I return.

Pulled the line lock off the car as it was causing problems. At least my breaks work again. :)

No chute yet. Assuming 3000 lbs car it needs about 800hp to trap/finish at 150mph. Now with the engine swap, I'll definitely need one. I'm shooting for 800+ on motor and then add 200-400+ on the bottle. So easily north of 1000 hp street car. :D
Of course that's pretty far off. So I may just have to buy a bigger garage. :)

New radiator is in place. Fans are reinstalled but need to modify one of the brackets. Test n' tune at the local tracks are Nov 11, 18, and 25th. Will shoot for the 11th at the moment. Track is 1 hr away and only 1/8 mile but good enough for baseline. Old car went 7.4x's there hoping the new car will break into the 6.xxx which equates to a high 10 second pass on motor. I'd be happy with that. Bottle will be hooked up over winter for more fun in the spring. :)

Got some new fire retardant gear for my bday. :) If the worst happens....

Smaller space. 1/8 mile and 1/4 mile need different lengths for shut down area. 1/4 mile is expensive to build maintain and you need a long stretch of straight, flat land. Less speed and danger with 1/8 mile. All the challenges of getting the power to hook and shifting gears without the top end sideways sashay at 130+

The builder said they're happy to put together some upgrades and change out the cam for a nitrous friendly one. So far this option is looking pretty good. And of course will cause all sorts of other problems going from a small block to a big block.

Well, the tire situation didn't go as planned. I need to lower the rear ride height 1-2" and check the geometry and hopefully allow for more clearance. Otherwise, I may be cutting the rear fenders some. :(

Took the car out for a short trip to get it weighed at a local landfill. With me in winter attire (201 lbs) she weighed in at 3220. So race weight w/o me is about 3,020 lbs. With a brake system swap, I can pull a good 80 lbs out, so that's on the list. So it weighs about as much as a nice Honda Civic.

The car did fairly well, it ran too cold with the new radiator and dropped a hole on the way back, will be going back to the 180* stat. I tried a couple test hits with the slicks and she still spun through 1st and 2nd pedaling it which is impressive. The slicks are taller than the street tires, soft sidewall, and much softer compound on 18 lbs of air so they should grip a lot better. Tracks open in March if the weather is nice, I foresee some suspension tuning in my future. Rear shocks are set very hard at the moment.

Lowered the rear suspension 1" and opened the coilovers 1/4" along with softening the rear shocks 2 settings. 1-6 are my options.
Rear disc conversion was ordered today.
Replaced the linelock and tested it. Need to make some custom brake lines but nothing serious.
Also rewired the new radiator fan and replaced and orginal relay for the headlights. Yeah, a 50 year old relay was still working...

Over the past few days I've pulled the top end off the motor. There was a fuel leak coming from the carb and a coolant leak from one of the head bolts. Drained the oil and sure enough, chocolate milkshake. Easy enough, but found they clearanced the rockers with a dremel to fit over the triple valve springs. When checking everything I found 3 rocker arm studs were bent. Why didn't they upgrade to 7/16", I'll never know. Replaced head gaskets, then moved to the intake. Gaskets matched that but not the cylinder heads. Why didn't they port the intake w/ the heads? That's easy and free horse power? For an Edelbrock Victor Jr intake, the casting leaves a lot to be desired. But I'm not dealing w/ it on this trip.

Chased all bolt holes, reinstalled studs, heads, and all the valve train that I could (waiting on the replacement studs), alternator, intake are back on. Exhaust is back on, btw there were no gaskets between the collectors and tubing??? huh? And the copper header gaskets were leaking so I replaced those. Going to rebuild the carb this afternoon, added the N2O plate and trimmed the gaskets to fit, pulled the carb studs and loc-tite them into the manifold. Pics below, but progress is being made.

Damn, my staysail will be simple compared to this! Of course, you aren't doing this 40 feet in the air!

Fun to see. The bent rocker arm studs will change your valve timing just a bit. Just something to keep in the back of your mind.

I'm always amazed that folks don't port heads, both intake and exhaust, as the first step. Everything is so much easier once the engine can breath well. I ended up building the intake manifolds for the Morgan when I went to dual Webers - what a difference!!!

Ha! Yeah, cutting a hole 40' in the air from a string is pretty tricky. But the install instructions and template should help greatly. All in all, boats are pretty easy once you calc the loading and safety factors. I do like 12v systems though. Pretty hard to hurt yourself w/ a boat or car. :)

I agree beau, the heads have a CNC'd port job on them. The intake, nothing. There's at least 1/4" that can be opened up on the intake manifold to match it to the heads and the flange at the carb necks down way too fast. I'll try and get a photo of that since it's already bolted down, but it's pretty ugly.

Edit for photo found online before and after porting. The bumps under the carb flange are what bother me the most. That, and the intake to head doesn't match worth a darn.

Update, replacing the rear brakes from drum to disc drag brakes has been no so much fun. The parts they sent weren't correct, of course I found that out after modifying them. Got different brackets and put them on. Test drive resulted in the brakes dragging, limping home, didn't limp enough and they caught on fire. Luckily I had an extinguisher in the car which put out the flame. The seal on the caliper pistons blew and squirted brake fluid onto the hot brakes. Whatever the flash point is of brake fluid, that's what they were at b/c it reignited quickly. I put it out again and rinse and repeat until I'm out of powder ABC extinguisher. Only thing I had on me was a couple cucumbers for a cookout later, so I break one in 1/2 and jam it on the offending caliper to take some heat out of it. Not the smartest thing I've done, but I'll be damned if I'm watching my Camaro go up in flames on the side of the road. In the mean time, someone called the fire department, to which they replied "I've never seen someone put out a fire with a cucumber". Fast forward and hour later, and a rescue vehicle arrives to wisp away my girl to safety.

One problem (which I found out after 3 phone calls) is that they used 2 different bearings which required 2 different offsets on where the wheel bearing is pressed onto the axle. The other issue is that this is a Chevy Camaro which came with a 12 bolt rear and stock axles. Now is has a narrowed Dana 60 rear from a Ford 250 with aftermarket axles and suspension. You can't exactly pick up replacement parts from your local Autozone. But it is coming along.

I've removed the rear brakes and junked them (no photos but the rotors were cooked and the calipers were charred badly). Received front brake kit and new lines, proportioning valve, master cylinder, etc. Everything will be replaced with new. Fronts were mounted up Sunday evening, just need new brake lines. And surprise, Strange engineering (appropriately named...) uses different wheel studs, so why not a new package of lug nuts while we're at it.
front.jpg


The slicks barely fit. Like I have to deflate them to get them in the wheel well. So, I rolled the fenders and picked up an inch of clearance. Of course I had to modify the tool b/c it's not supposed to work on a narrowed rear end.
rollin.jpg


And if I get bored, I start making things shiny, did the door handles and mirrors. One mirror was not salvageable. New one on order.
mirror.jpg


Pulled the rear trunk lid as my new fiberglass hood and lid showed up. There will be some trimming, drilling and pop riveting, and then take it all apart to get painted. Then put it all back together again without scratching stuff.

I have settled on the engine I linked to earlier with a few upgrades. The builder is happy to accommodate these request and is helping with the selection.

632 cubic inch engine (for you people who do weird math that's 10.4 liters).
Upgraded heads and keep it at 10.5-11.0 compression for pump gas.
upgrade cam to solid roller from hydraulic roller. I don't mind the added maintenance for the performance boost.
Ring gap opened up for a lot of nitrous, probably 0.032 like my last engine. (400-500 hp shot).

All told N/A we're shooting for 900hp on pump gas and 400+ race fuel for enough to get me to an 8.50 ET. Should be plenty of power (1300+) and I don't want to upgrade to a funny car cage which is needed for an 8.5 second pass. I'll try to keep the install pics up to date a bit better.

Very cool upgrades. Sorry to hear about the brake woes. Can't say I've heard of someone putting out a fire with a cucumber either. Quick thinking though.

It would've been nice if they included ANY instructions at all in the $800 box I purchased. :evil: You know, something to the effect of, Hey, check the distance between the axle flange and axle tube flange. It should be x.xx" and again, these brakes are not stock, require shims to center the 4 piston calipers on the 2 piece rotor, not a 1 to 1 replacement. Not only that, but I bought the front kit and all new brake system for the whole car and they wouldn't give me a break on the price for replacing the rears that were torched. Oh well. At least I'll have full faith the car will stop from 150 in a short period of time.

Started on the brake lines. Bought a kit, and not sure I'd do it again. I'm sure it works great for a stock car, but nothing is lining up on this one. I might be able to use 2 lines out of the kit. Oh well, should've made my own.
Got the hood off, installed the master cylinder (pushrod is too short) so will need to address that. Rear axles are pulled out and off to the shop to get bearings pressed to correct location. Old hood is off. New rear brakes should be here today, with any luck I'll be able to get the brakes and axles done this week. Then move to fitting the new body panels.

Go figure, just heard from the shop, the wheel bearings are pressed on as far as they can go. So it's either pull the bearings off, and cut the shoulder down to press them on farther, or buy new axle$. Ugh. All this b/c I wanted disc brakes...
