LQ4 with T-Rex--- Add LSA heads
Hi,
I currently have a stock LQ4, T-Rex camshaft, LS6 intake, ported throttle body, electric water pump, long tubes with cats...
I have a set of LSA heads sitting on the shelf and desiding on either selling them and going turbo or throw them on and keep it N/A.
The QUESTION is LQ4, LSA heads (holley low boy intake manafold), T Rex cam and a E85 get me to 550RWHP?

Your probably looking 480ish rwhp with that setup. 550rwhp is no ease task n/a, you will probably need a 408 with ported lsa to safely get you there. Plus a Lq4 with lsa head's is only a 9.5-1 engine.

wrong heads for that cam, youll need some light valves and good springs with high seat pressure to tame that cam.
with a 2.0 valve it only has .011 clearance i dont see it clearing with a 2.16 valve
valve float will be encountered over 6000
