The 63 and 64 use ther same rods. The crank and bore are the only differences. Marco was probably the first to start using "long rods" in a '64. Basically, you use the '63 "stroker pistons", which have a raised pin height to compensate for the added stroke, in a 64 block, which helps give you an extra 6mm to add to rod length. The 2.5 will already use pistons with a slightly raised pin height to accomodate the added stroke from the 102mm crank, and raising it a few more mm would require custom rods.

Also the 64 has a 6mm taller deck height, but very good explanation.

I would like to hope so, but I feel you may be a bit high on your estimates. Remember, this is a pump gas/meth injection car. I think 30psi might be a stretch.

Wow, that's great low end power for such a big turbo. Isn't that wheel over 75 lb/ min? It's making power down low like a 35 on a 2.0.

I think cams are the next step. Yes you heard me, our Evo IX made that power with STOCK CAMS.(Still trying to get the video up for you)
