OK so I need your help. Since your already talking about the 340. I have a 67 Barracuda fastback that weighs 3140 without me and 3300 with me in it. It has a 68 340.
340 .030 over TRW forged shaved to flat tops 10.5.1 comp.
X heads with some cleaning and port work
Lunati voodoo 284/292 533/552 hyd cam
RPM airgap intake
750 holley vacuum sec.
70 340 sixpack exhaust manifolds with no heat risers.
2.5 in.exh. with magna flow mufflers dumped in front of the rearend.
727 auto. with converter that stalls to about 2300 rpm.
8.75 suregrip with 3.91 gears and 275 60 15 tires(28 in. tall).
rev-n-nator ign.
This combo is horrible off the line and I am sure the cam is the problem running the gear, tire size, and stall that I have.
This is my best run
r/t... .228
60'... 2.193
330... 5.195
1/8... 8.946
mph... 81.40
1000... 11.55
E/T... 13.767
MPH... 101.35
Looking for suggestions on cam choices staying with a hyd. because it sees a lot of cruising time. Comp XE274H cam? maybe.
Makes power and torque at a lower rpm to get it out of the whole and still good up to 6200 rpm. Any help would be appreciated. It would not even spin off the line going around the burn off box straight to the starting line. The voodoo cam really needs a true 4.10 gear and 3500 stall to make it perform well. My fault live and learn, but it does sound really good.
