Long tubes,4.10 gears,3000-3200 circle d stall,bulit tranny,cold air,full exhaust,hp tune,cam 224/228 112lsa- doing 355 whp and 341 torque. Does this sound about right. And what can i do to add more power. I was told a ls6 intake and trickflow heads and 36 to 48 lb injectors? I posted a copy of my tune and dyno sheet for looks or comments
Ported heads with a mill to up you compression. Those #'s seem pretty good for a 5.3 with that cam. The ls6 intake will help depending what you have now. What vehicle is this in?
I was told the ls6 intake is too much work to make it work. Someone said get the intake from a 07+ silverado nnbs. Mines is a 05 silverado crewcab. I have the 706 heads. Is it worth porting and milling or get the 243/799 head and do that and shave .030 off to bring it back down to my stock compression
