turbo cam question
#1
been tossing around different ideas lately and have finally landed on turboing my 08 ccsb 5.3
i have a few questions though. first i had bought a cam awhile back its a comp cam 231/239 (i know some may say its too big of a cam) but i was wondering if anyone would have any idea how it would be in a turboed 5.3?
if no one has any idea for that cam which cam would people suggest to run?
also going to be taking info on what size converter you would suggest for this setup. will be swapping in a 4l80.
also i guess i should say i am going to be going with the on3 kit either 70 or 76mm, once the nnbs kits are released.

Too much cam for either of those turbos. I would take it down to a 21x by 21x with close to 0 overlap. Will drive much better and be a better fit. A 2600-3000 stall would be fine too.

My 5.3 will have a 70mm and I'm running the triple 12 from stock48. I'm pretty happy with it. Starts running good from 2500 all the way up to 6400. A 2600-2800 stall would make it perfect.
