When reved up to anything above 2000rpm. (and held while parked)

I have 3 guesses.

All the above...and add Check Plug Wires & Plugs
Make sure and check the muffler bearing....:3dSMILE:
the plugs are new.
the wires should be good. a lil over a year old MSD 8mm wires.
Is it intermittent or does it seem like one cylinder misfiring?Quote:

Wooow, I am really surprised to see a Timkin in there. I use the smaller ball bearings in mine. Actually I found a cheaper source for the ball bearings. I use shot from a 12 ga. . I don't know if yer' spoz' ta' use them cuz' of the new no lead laws, but hey, it works for me. While I got yer attention, I gotta ask ...... How do you keep seals on that bearing? My guess would be some sort of ceramic unit or a dry lube injector... How am I doin'????Quote:

Depends too if the johnson rods are carbon core or copper core.Quote:

:HMMM: ..Geeze....How about a .....lets see here..:HMMM: .......A complete tune up.???.......Tweek the giggling pins too.......Hey Viking.!!.....whats the part # for that muffler bearing anyhow.???...:confused: .....:whacked:
An ohm meter should tell the story on your plug wires. How about the cap, rotor, advance mechanism, and general wear on the distriblutor??? Did a leak down check show all the cylinders to be good, or are you trying to fix a valve problem with ignition peieces???
How about pulling one plug wire at a time to locate the bad cylinder, then go from there.

:3dSMILE: not sure of that #, that pic was a file photo, a ricer exhaust, I believe the failure was caused buy burnin un-leaded rice. :3dSMILE:Quote:

oh got to keep those V8s hittin on all 8!
ive had some valve springs go bad, idles ok but once on the gas shes a V7 - find the dead hole (via pullin wires or a compression check) then you can pull your tappet cover off & watch your springs go UP & DOWN & you may even get shot with some dirty motor oil!?!?! if your lucky! LOL!!!!!!!!
All cylinders are are within 18 psi.
149-167psi. 7 cylinders are 158-167.
cylinder 4 is 149 psi.
My motor runs perdy good.
I Just want a big improvement in power.
So I will just run this motor till I build a big block to swap in.
I made the same mistake once; built a 355 when I shoulda built a big block for my trailer towing rig and now I gotta live with it. Had a similar miss when we first had it running but it was just the lash adjustment on an exhaust valve was too tight. Might help. Good Luck!
