Cam shaft suggestions
the computer camshaft is my problem! According to Chrysler , the computer advances ign 55+ degrees off idle . Have been told I need a totally re engineered cam the dist only gives approx 28 degrees total advance
I don't know where you're getting that load of bull.
The cam doesn't care if the ignition and advance is supplied by a computer or an ECU with a mechanical/vacuum advance distributor.
Your cam specs are:
432/432 lift
31* overlap
113 centerline ( a little much, but not a deal breaker)
115 installed.
I run this exact cam in my Dakota (2.9x ish gears) with a Holley 600 4 bbl. and Chrysler electronic ignition, and I've got enough bottom end to peel your lips back even pulling a trailer... You've got something else going on.
Make sure your advances are both working- vacuum and mechanical (your vacuum advance IS hooked up to a ported vacuum source and not manifold, right?). Make sure you've got at least 15* initial dialed in, give it more if your engine likes it. You should be looking at close to 40* total...
You didn't say what you're running for a carb- hopefully you're not trying to still run the computerized "feedback" 2 bbl.- if so, that could be the majority of your problem. It requires input from the computer (now gone) to function correctly. If you have a different carb, go through the usual diagnostics to make sure it's performing as it should.
Bottom line is that bottom end should not be an issue with this cam.
