Just wondering what cam I could go with without changing my factory manifolds so i can keep quiet choice? And what kind of hp am I limited of making using my stock manifolds without supercharging

I'm planing on pulling my motor this winter and would like to make some more hp

you are already at the max duration wise.(224/224 @.050 or somewhere there abouts) You could go higher on the lift and shorten the gross duration and it would run stronger and should still work decent with the stock intake.....no sense in going much bigger with that intake anyway.

Next question is if the intake is a bottle neck should I keep the efi or go carb
I'd like to be around 600hp but also be reliable also
