Jury is in..... Holley Street Dominator vs. Factory Cast

!st question is, is this intake heated...or are You using block-off gaskets?
2nd is, a head wind is nothing to discount?
3rd, w/o re-jetting, You're definitely cheating the aluminum intake if current jets are "on" for the iron combo..............I'm guessing no?

1st - heads are blocked off by carbon so no heat to either intake.... LOL
2nd - slight head wind, but some racers I know were not being affected by either mph or E.T.
3nd - Didn't re-jet..... for either intake. I do have 2 sizes bigger jets on the primary of the 670 Street Avenger.
