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
