Great build, very inspiring!
What size rear tires and what is the final weight of the car?

Thank you!

I ended up with a Hoosier 29.5/11.5W I think about 96 roll out. My son has built one since with a 100 roll out radial. I have not run it at weight yet, my minimum is 2870 with the L-98 engine combo. I will say that is not a problem. The lightest I have raced it thus far is 2980.

Let me know if you need anything else. Are you building one?

Dude I need to put you on a plane to Denver and turn you loose on my car and dial in the combo for me! 67 camaro 327, same class but at least I know I got the right tires on it! Same hoosiers you run.

Looks great, I have a few questions for you.

Hi Ernie,

Wow - this was a good thread to look at. Ive been racing a C4 for about 18 years and did a semi 4 link years ago that bolted in. I used a 12 bolt and at the time had a 434sbc that went a best of 9.7@136. However a few years ago after that sbc blew I put in a 555 n/a and been racing that for last 3 years. Detuned it goes 9.0@153. My car is still all stock inside with moly cage of course and has power everything yet. Even the stereo is still in it.

With the 12 bolt even detuned I usually go through a ring and pinion at the most inopportune time (semis). So this winter I plan to put some big tires and let it really eat. If I turn it up it usually goes about 1.26 60fts but it really taxes the rear. I plan on a 9inch.

The car is used for bracket racing and where I have it detuned it works great but I am wanting to get it more realiable. So basically I am cutting apart a perfectly good car that works like a zerox machine.

Few questions. Do you have some more detailed photos of the area around where the frame connects. I have seen several of these cars done with the crossmember just tied in straight across. I plan to reinforce mine with some 45 degree tubes also tied into the frame adjacent to where the seats are (drivers hip) area.

I am planning on Hoosier 18300 and weld Alpha 1 15x15 wheels. What size did you go with? I figure I am going to go a little overboard as I dont wan this thing to even think about spinning - some of the tracks we race get a little hairy late in the rounds when the dew sets in.

Are talking the front where the birdcage connects?

My son has since built one for David Tincher. He used a crossmember straight across and trianglulated a bar inside the floor.
I use a 29.5X11.5W, They run a radial on Tinchers car.

I am reffering to the area around where the stock 4 link brackets bolted in. Just inside of that area I have seen people run the crossmember straight across to other side. I see you really chopped that area away.

Straight across is what I planned on doing and then to further reinforce it put two 45degree bars up to the frame rail area adjacent where your outside left hip would be if you were sitting in the drivers seat of the car. The other bar would be your passengers outside right hip area.

I already have a slick way to hold up trans and not compromise ground clearance. I plan on just utilizing that way with the new build.
