The heads are afr cnc 210's 64 cc and the short turn radius has been cleaned up they flowed 298 cfm @ .700 lift..
the cam is a solid roller comp with 268 and 272 duration with .634 lift
the intake is a super victor that has been ported by larry meaux.
update
i decided to look at my fuel delivery so i firs of changed my feul filter on my suction side to a good wix filter........phoned aeromotive to find out how much my pump will take to pump 1 galoon.
So i took the line off before it goes into the regulator and put it in a gas can and got my son with a stop watch and started the test........i was told it will take 26.7 seconds to get a galoon....well it is no problem as it pumped a galoon which equates to 138 galoons per hour.
So then i phoned holley and told them my problem and what i wanted to now was what needle and seats should it have he told me i should have .120 so i took out the ones in it and they .097 and replaced them with the .120 after this i had to lower my fuel pressure as it jumped up to 9 psi from 8 psi wierd what ever..................i am hoping for the cheap fix and maybe all what was wrong was the needle wouldn't let enough fuel in...........fingers crossed
Would be nice if it was that simple.
