Boost Question Whats up guys.... I'm trying to finish my TA and I about to order the pistons, but before I do, I'd like to know if a 10-12psi is possible with a Compression ratio of 9:1 to 9.5:1 on 93 octane for the street? I'll be running the MSD Boost Timing Module, Custom Tune, 50# injectors, and some nasty fuel pump... Thats the other question, does anyone know where I can find a Walbro 320lph to make work in the car? Thanks everyone

I forget, what size are stock LT1 rockers, 1.5 or 1.6?
If you ported LT4's, why not go with more lift on the cam? What do the heads flow from 450-600? If the heads kick *** at say 575 but fall off big at 600 then you would want to give that info to the cam company. My heads for example are decent to 600 lift but don't really increase that much to 650. If I had a set of heads that rocked to 650 I would gain power.
