Re: Tbi to HSR

I'm sure it does, a 7.4 only flows 650 cfm or so and LS1 are up to 750ish I believe.

I'm still not convinced that's better than a HSR. The HSR is $510 for the intake and the rails. And the...

9:1 can be ok, it depends what you do with it. If you run a mild cam, it's not a bad place to be.

It's probably a low compression engine with junky heads. I wouldn't pay extra cause it's a "crate engine."

Re: .500" lift on LO3 heads? (going for broke with a LO3)

They're both "Swirl Ports," the Vortec is just a much improved design that flows better. Both should swirl the air and fuel nicely and produce the desired "fast-burn" combustion.
