As i say in many of my replies, I'm having a 347 built. With the great info gathered from this forum I decided on the following: the motor will have a 9.0cr or 9.5 at most (possible blower in the future). I'll be going with forged pistons with reliefs for 2.02 T/W heads. It'll have a forged crank with forged I-beams (H-beams do not seem necessary for motors under 1000hp). T/W o-ringed heads, the stock Cobra lower will be ported, the upper will have the TB opening ported to 79mm, a BBK 75mm TB, and a custom cam (most likely from FTI).
What I want to know is things like what type of cam spec should I be looking at? I will be using the Cobra pcm, so I believe I need a LSA of 15 or more. How much lift and duration should I consider.
I am also looking at new headers. Unsure if I sould just change to larger Shorties or go to LT's which would mean a new H-pipe as well (more $). The car will be 95% street driven with occassional track use. I want to keep the 3.55 gears and 77mm MAF. I have 24lb injectors but would would also consider uograding. Unsure of which to use. A 255 fuel pump is on order. I am on a flexible budget which means I'd like to re-use/modify what I can and replace(buy) if absolutely necessary. I am also aware of the minor things like new ARP bolts and gaskets.
