360 Cylinder Pressures

KevC said

The Thumpr cam comes in at 2000rpm, the Xtreme Energy one comes in at 1300rpm.

We didn't try a second gauge, but 2 Mopar guys over here say the Thump range are useless for anything other than an unstable idle, and the cam is the problem coupled with the 360's relatively low compression.
Anyway, really appreciate all your experience and input but I guess I will just bite the bullet and install the new cam and see what the result is.
I'll keep you posted.

If it's installed wrong, it won't matter what the book says about where the cam comes on.

Did you check the installed centerline before tearing it down?
What were the readings from the wet compression test?

The camshaft likely wasn't the issue in your case. I've run 284/484 mopar cams, bigger than the thmpr by 14* at .050, in 8:1 360's that would KILL the tires. According to the books, it shouldn't run well.

I'll bet the thmpr cam installed centerline was way off the mark and the timing was a not up to snuff.

Care to answer the ignition timing question or is that not important? :)

I'm not a rocket appliance, but, I stayed in a holiday inn last night! :)
