86 w/ 350 swap tpi has a slight miss, sounds like popcorn out the exhaust but runs ok..
but it only misses when the esc wire is connected, with it unplugged it runs very smooth(no miss)

so i believer that puts it around i need a new esc/ or knock sensor..

maybe they never swapped that out when they did the 305 to 350 swap?

any ideas?

 

Any ideas?

 

Could be too advanced reset timing with the ESC disconnected

 

With it disconnected its at 6* tdc

 

sensor then.

 

what sensor?
the knock sensor? Or the esm or icm?

 

Or perhaps ill play with the timing?

wouldnt the timing be different on a lower compression gm goodwrench 350? Its cam is the larger one.(not like it matters with the 76cc heads)
but would 6* still be the base for that?
or would it be lower or higher due to high and low compression?

 

Could this be the problem?
