Re: Gen VI 489ci bored .020 & stroked to 502ci 10.2"
Not sure I would have bought that intake! I think with your combo only making 540Hp, that might be a bit of a lose with the intake, and if you're going to get the correct aftermarket intake, get the oval port as it WILL work better all things considered.
I probably would have went with the original intake you got, blasted it back to raw aluminum, and ground of the name. BUT we also didn't get cam specs either. I made about more than 220+Hp more with my 198 OEM ported dual plane on my 475 then what your motor is making! So you know you can make lots of power with a dual plane.
