LQ4 with T-Rex, LSA heads e85 or turbo? 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 manifold), T Rex cam and a E85 get me to 550RWHP?

550rwhp is 408/414ci+ stroker territory. Hitting that number using stock cubes will be one tough feat for sure. Secondly, that cam is an old grind designed for stock LS1 heads. It is not ideal for what you are trying to do IMO. You're going to need to contact a vendor to spec you a custom grind for your setup.
Here's a good starting point:

Good luck!

I did the heads cam thing for a while. its cool raping Hondas, sti, mustangs and anything dodge has. If you want to put a hurt on vipers, lambos, supras go turbo. you can go from 400rwhp to 700 rwhp all by turning a a ****. Stock 5.3s take a beating lol. I would never go back unless I had an ls7. FI is superior in every way if you can afford it.
