Go ahead and pull the valve covers and make sure none of the springs are broken.

probably wouldn't hurt to take a look would it....although at idle or a tad bit more there is no problem, it's just under load/and anything other than light acceleration

It may have already been mentioned but double and triple check the plug wires, could be a couple swapped.

Running rich will cause an engine surge at idle, but your pop sounds like either a lean misfire or a lifter pumping up. Did you restab your dist? The reluctor wheel syncs your injectors and if your #1 plug wire is not in the correct location it will cause injector sequence issues, For example if your a tooth off and have to move the wires on the cap to get enough dist. movement to time the engine.

I had a valve spring break on me a couple years ago.

For the most part, it seemed to run fine at idle and cruising speeds, but it would miss and pop through the intake under the slightest load.

been helping a friend/neighbor move the last 2 days and have about 3 more hours worth of work....(time to catch up on all my yards) THEN I can maybe take a look at this....thanks for the suggestions guys. I will check wires again, but have done that several times (not to say a little gremlin didn't swap them)

I'll report back with results one way or the other

Brad

got it running ALOT better today...think the combination of a speed density map/bap and a blockage in the fuel line had something to do with it (mostly map/bap) I blew out the fuel lines with some air and along with a new filter and some 93 octane gas it runs ALOT better...will have updated pics/video this evening when my son gets home from his fieldtrip (got the camera)....
