faced with having to redo the 196 a 3rd time I've given up on it.
Looks like way back in the process the machine shop got one piston a little smaller than the bore. New machine shop and mechanic say no problem to punch it out .30 over and put properly sized pistons in. It will go up for sale in the classifieds here shortly.
I've committed to the GM v6 swap. Reviewing a possible motor source now and from there will start gathering the goodies to go with it. Will go carbed for now and use my existing edis for ignition.
