gas pedal
 

for my ls swap, i was told that a 06-07 chevy truck with 799/243 heads will work best with a turbo... My question is, will i have to change the gas pedal out somehow for a dbw. Or can i use a cable? thanks

I coulda sworn I read that thread lol. Why did you want to go with a higher compression head along with a turbo setup? I'd think you'd be better off taking advantage of the lower compression that the 317's would offer.
799/243 DO flow better but would raise compression on a 6L to about 10.4:1 with a stock gasket.

That doesn't answer your question tho. Which intake are you planning on using? I think that has more impact on TB choice than the heads, unless u go to an l92 style setup.

Which year would you recommend. I'm reading on yellowbullet and that's what they are saying, but not sure....

You can purchase aftermarket throttle bodies for cable use. Factory throttle bodies can be used on the earlier intakes I'd say 05 back. 317's and 243/799 heads all flow approximately the same just the 317's have a larger combustion chamber. Buddy of mine just built a stock bottom end ls2 with junkyard l92 heads and single turbo. This setup made 963hp to the wheels. Hope this helps and good luck with the build.
