don`t know the answer to this one, but I had a brand new 68 form. S fastback. the book said it was a road runner engine, w/ a pinched down exh. manifold on the drvers side. the tires back then weren`t to great, the fish wouldn`t touch the ground when I got on it, like it was on ice! big fun for a 22 yr.old!

[mikedevore]

Jim, the AMX is the logical choice.

Are we drag or road racing them? AMX is better in the turns that's for sure

1/4 Mile 'Heads Up'

Race 1 > 'Stock' E70 x 14" Tires = {6.25" x 26"}
Race 2 > 'Prowler' Cheater Slicks = {8.00" x 27.25"}

* Exhaust Header Manifold {Log-Type}
* 2" Exhaust Header Manifold Outlet
* 2" Front Pipe
* 2" Intermediate Pipe
* 2" Muffler Inlet

While the Exhaust Manifolds were considered 'fair' at best for Exhaust-Flow, the rest of the
