I couldn't agree more. The difference between 20* and 23* on my ricer was night and day. I went from decent traction in 2nd gear to pretty much no traction. Then from 5,250+ I gave it 25 total (with boost) and it just was not the same car. I assume the Edelbrock heads are not a fast burn design, and they're aluminum, and the CR sucks so they'd need to run more to make up for the inefficiency anyway, that motor'd probably take quite a bit of timing. But then again they didn't tune the Ford worth a shjt either, so how much has yet to be unlocked from it?
