Hi everyone .. I was wondering if anyone could help me to tackle this problem I have with my 65 fastback. the car is virtually undrivable due to bucking and jerking in any gear at less than 2200 rpm In traffic I have to constantly change down and usually finish up in first or second gear to keep the revs up .. above 2200 it pulls really well and will cruise at 2500 3000 revs all day with no probs .. you can see the engine specs from my sig. I thought it may be the cam as it is a bit on the wild side and gives power from 2500 rpm, but below this it should still be streetable but not a lot of grunt when floored at lower revs. Before this cam I had an edelbrock performer RPM cam which looking back the car was not too different than with this cam. I tried a holley street avenger 670 cfm with vac secondaries and the car seemed slightly better with that .. but still not streetable. It is only pulling around 5 to 6 in. of vaccuum at idle.
I really want to get this sorted out and would like advice on the logical steps to take.
Thanks in advance.
