Default 370 LQ4 with LS3 heads?

Alright so its time for me to start a new build for my car heres the rough thats going in

2004 LQ4 stroked .030 over
LS7 lifters
Holley Hi Ram
Futral F14 cam 232"/234" .598"/.598" 114LSA - or their high lift version 232"/234" .646"/.612" 114LSA -
TSP LS3 heads
60# injectors

and the car will get a turbo later on down the road, just wondering if the cam i chose will hurt a little on with a turbo

In my opinion, that cam is not right for the LS3 heads, or a turbo in the future. If you want a Futral cam, have him spec you out a different one. That cam is meant for cathedral port heads and is not the most turbo friendly cam.

cam is not right for those heads. and imo if your going to go boost later on get the LSA heads. thicker deck and made out of a better aluminum. the LS3 heads have been known to lift under high boost.

If you want an off the shelf cam, then get one meant for the LS3 heads, but like I said earlier, get a custom cam, especially since you'll be going turbo down the road.

Would LS9 heads give a better flow than LSAs? can ls9 heads be bolted onto a LQ?

Why are you opposed to the LSA heads?
