Sorry, I just saw your post.

Mine has 70 4V quench heads that have been modified. It has a hydr roller cam and roller rockers. The intake is a stock 70 4V intake.

I am very pleased with the performance! It dynoed with a torker intake with 532 HP & 510 tq. I took the torker off so my Ram Air could be used.

I can get you the complete specs tomorrow.

Thanks for the info mine is finally starting to come together. Ran into some alignment issues with my March Pulley system last night. I may have the wrong bottom pulley or the wrong one for my balancer anyway. Waiting to talk to tech at March now.

What balancer are you running? I am running a ATI Performance Products balancer and I had to get an adapter to get my pulleys to align.

Its a Performance Quotient (PRW) 2430203 fluid filled one. Talked with march last night and they have a 351 windsor crank pulley that looks and measures like it will align every thing up. Will order today and find out.
