so I just picked up an 87 gn with the engine on a stand. last week i tore down the shortblock to find out its already 040 over, and 3 out of 6 pistons were cracked all the way down the skirt. so now my engine builder tells me pistons are only available up to 040, so now im searching for a new block.

if anybody in northern california has a standard bore 109 block, pm me please. im up against a brick wall until i find one, and i'd like to get this car back on the road before the end of summer at least.

thanks

it may be, but piston options are slim to none for the turbo engine. not a problem going 60 over on a non turbo 3.8, plus im not sure how thin you're cutting the cylinder wall going 60 over.
