Yeah, you can't build a motor to run well N/A then slap a FI setup on and expect it to do well. You'd be better off getting the turbo on now and get it tuned with that since compression seems to be your main problem. If you want to do a N20 setup, then you need to redo the motor and get it running great N/A. You'll just have to adjust a few things like spark plugs and timing to run the nitrous. Good Luck.

I'd keep the heads and port them.
The cam is wacked. As someone else stated, too much duration, not enough lift. Bad combo there. Do a know what the LSA is?
Also, is it an auto? with a stall? Did he run it unlocked? That'll kill the numbers.
Edit: I see its an auto. How much stall? and did he run it unlocked? Thats gonna make a big difference in the numbers. could be 30+ depending on the stall.

its a 540 lift cam with 1.5rr but i have 1.6rr to bring the lift up. It has a 3000 stall in it. don't know if its unlocked or lock. its a pro torque converter. yes i know what a lsa cam is.

if you want to hit over 500rwhp to 550rwhp, then port the heads and throw a blower on it, chances are your not going to want 500 +hp because you would have to set your whole car up for it just to race, which equals a lot of money. Throw a blower on it and it will make great power, probably somewhere in the 450rwhp

That thing must not peak for ages with all that duration!
If your running ported heads and a cam, you gotta complete the valvetrain.
Roller Rockers, Roller Lifters, Dual ValveSprings/Bee"Springs, new guideplates shims, locks.
Might as well get a custom cam or a better cam for your setup, put in the new valvetrain components and injectors, then have it tuned.
A dyno tune is a must IMO with such a mixed setup.
355hp/370tq isn't too bad though, they are nice numbers, but you should be closer to 390-400 the way its sitting now.
Good luck man.

And I'm not asking you if you know what a LSA cam is, I'm asking you if you know what the Lobe Seperation Angle is of YOUR cam.
