misfire under load.
 

I was browsing as a new member and curious as to what subjects are discussed and found your forum. The only answer I saw as correct for your particular symptoms was a bad cam which can happen very quickly on a new motor if certain things come into play. If you checked to see if a rocker arm seemed to not be moving a proper lift that would indicate a worn cam lobe. These things happen and I'd be intereted in knowing if you did solve your problem.

Well, after a few beers and a little turning of a wrench, I added a shim under the rocker arm on the intake side of the #1, and presto-chango no more popping! I guess when I had my heads done, the valve seat was off just enough to make the difference. After 2-1/2 years, I finally got the grin back on my face when I took it for a drive!

Thank You Everyone for all the help and replies!!! I'll post up some pics when I get a chance.

Thanks again!!!

John,

Glad you figured it out. NOTHING is like that grin you mentioned after all that hard work. It is a closure that brings much pride & happiness... kind of like an automotive orgasm.

Check the valves settings
again :D :D
