Inliners International Forums General Discussion Blown and Injected Hacking together EFI on an Pontiac OHC Six

You mainly want to focus on the intake manifold matched up, no steps.
Unless you figured to port window is too small to begin with.

You do not want open up the entry just because the gasket is that big.

You want the port velocity high, making ports too big can make havoc on the low RPM response.

You do not want to air to slow down then pick up speed & then slow it down.
I suck at explaining this stuff, sorry.
