cool...if you just plan on getting the t-body...get that last. but the t-body and the upper plenum,(c&l or accufab) would make a good combo.10-15 rwhp. and this combo with intake and maf would be great.
Don't buy an Accufab if you want to use a 75mm tbody, they are designed for a 70mm tbody. Go with a C&L, Trick Flow, or Dragon, I believe all of those will work fine with the 75mm tbody. You can port a stock tbody to work pretty well to work pretty well with a 70mm tbody, which is about what an Accufab looks like a polished on the outside, polished and ported stock plenum.
