I'm a little worried
I have been building my 70 Chevelle for a couple years now, I have put every penny that I made into it. It's coming very good and I fired the motor last week and it sounded very good. My dads friend has a "Run Stand" in his garage and we used that to run it, engine is not in the car yet.. No tranny. It will still be a long time before I can drive it, currently out of money.
Now my friend who gets whatever he asks for just got a '68 Camaro all resotored. It has a pretty good engine too, but I think my car will still eat his. Still there's always some concern that someones car is faster. He'll have it totaled in a few weeks anyway.

Here's the specs on our cars
Myn: 355 SBC
- Eagle rods
- GM steel crank
- Solid roller cam 600-620 lift 255-262 @50 110 seperation.
- 492 Camel Humps, ported and flowed 254cfm@500
Elgin Race Flo valves, Pocketed to 1.550 with Canfield Roller springs, appx 60cc chambers
- TRW pistons rated 12.7 @60cc
- Victor JR with modified Holley 750 double pump
- TH350 with 4000 stall

His car is a stock bodied '68 Camaro
- 355
- Comp Drag Race solid flat tappet cam 530-560 lift
- Victor JR heads
- 10:1 compression
- Super Victor intake
- 1 7/8 Hooker Super Comps
- 750 Demon
- Saginaw 4sp

I don't care who you are or how fast your car is there's always going to be someone out there that's faster. Not having the fastest car in town is no reason to worry. Just build what you like and have fun with it. If you wan't to really prove which combination (car and driver) is better go bracket racing. There the odds are even.

sounds like a good race, you should pull him out of the hole but watch out, if he doesnt miss any gear's he'll run you down!

Try a set of 28x10.5 super soft Mc Creary's on there and it will hook if your suspension is up to par...good luck! and hey, keep the racing at the track.....;)

that engine sounds expensive, and you're 15! whered you get all that money?

GearHead69 05-05-2004 06:52 PM

I agree, it's not worth the ticket and danger of racing on the streets. The tires on my car are 33x19.5x15 MT sportsmans and I'm running 4:88's, He's running 245x60's with 3:73's. I am deciding what tranny to put in my car, I think I'll find an old TH350 and rebuild it. I have a M21, Glide, and TH700R4 sitting in my barn they all need work and don't really work good in a Chevelle.

I traded my Kawasaki Mojave 4-wheeler for the car, engine, and a whole barn full of Chevelle parts. The car already had all the work done to it. The guy was an idiot. I will get some pics of my project when I borrow my dads camera.

Thats alot of car for a new driver to handle. The M-21 would work well in a Chevelle.

GearHead69 05-05-2004 08:25 PM

Yes it is a fast car. But since I'm doing all of the work myself I will be very smart when I drive it. Every time I get in the car I will think about all the hours and hard work I put into it and that will make me not want to do stupid things.

Would the M21 hold up turning those big tires? and would it handle the HP. Some guys tell me if I put a 4sp in my car I'll have clutches coming through the floor and be burning gears.

You heads were good in their day but the newer heads are much better. With that much cam 33" tall tires I'd go with more gear, like 5.57's. You're going to need 5000rpm stall convertor. You could keep your gears and convertor and go about 15 or 20 degrees milder cam, if it ever gets stret use it will drive much better that way.
You're a little too vague on your friends set to say who's going to win. You're going to need to make more power than him to beat him because your car weighs more and the auto trans is going to use up more horsepower.
You only gave the lift of his cam and no other specs. He has better heads but I'm guessing that you have more came a long with more compression. Just guessing, the dyno sim is on the other computer even if I did know his cam, but I bet your horsepower is near the same but he's going to have more torque through out his powerband. That's why you'll need the 5000 stall convertor. Your going to need to get that motor spun up and keep it there to do anything.

I am just curious but why are you running a 33'' tall tire?


GearHead69 05-05-2004 09:21 PM

I had a brain cramp and guessed: His cam is a Comp Sportsman Bracket cam 532-555 lift and 250-260 @50 with 106 lobe seperation. The heads on his are Victor Jr's with 215cc runners 64cc chambers, and 2.08/1.60's. Pretty big stuff for a 10:1 355

Why am I running 33" tires.. They came with the car when I got it and they are new. They are staying untill they need replaced.

Erk 05-05-2004 09:25 PM

I'd say he is going to take you IF you race.
Since your running 33'' you are going to need alot of gear to get those suckers going. Off the line you will take him. But after the line hes gonna be gaining and you'll be seeing his taillights.


killerformula 05-05-2004 10:27 PM

?? Are you sure you have 33" tires? I seriously doubt you do. Most 4x4 fullsize trucks do not come with tires that big.


GearHead69 05-06-2004 06:56 AM

I don't know if they are a true 33".. I have never measured them. They are 33x19.5x15 those numbers are probably over rated.

2wld4u 05-06-2004 07:22 AM

sounds like its tubed...hey! thats great! and trust me, your better off sticking with an automatic, High winding gear jammers are fun but if your parts arent up to spec you could possibly have shrapnel shooting up through the floorboard when you pop the clutch on a hard launch...the slush box isnt much better but there isnt as much driveline shock on take off...but.........there is a thing called a transbrake......;)

TurboS10 05-06-2004 07:55 AM

Well, he wieghs less and with those heads probably has the power figure it out.
