Absolutely. The ONLY parts that aren't interchangeable between a 2 bolt and 4 bolt block are the main bearing caps themselves. The crank, rods, pistons, camshaft, oil pump, etc, are ALL interchangeable. So yes, the pistons will work just fine.
You buy the correct crankshaft, rods, and pistons and install them in your block.
"small block" typically distinguishes between a 2 bolt and 4 bolt main. (Small block= 2 bolt main. Big/large block=4 bolt main) "long block" typically distinguishes between a rebuilt engine that has heads, rockers, rocker covers, oil pump, pan... in other words, complete, versus just block, crank, cam and pistons (short block).
A real LT-1 had a four bolt main block.
It is a small block Chevy 350 engine with 6 bolt main caps.
400, about.
It sure is ....i just purchased a donor block for my 98 silverado and sure enough it was a 4 bolt main block
None. The four bolt main block is thought to be more rigid at higher loads.
A Chevy 8970010 is a 4 bolt main 350 cubic inch engine. It is classified as a small block and is placed in a variety of automobiles from sedans to light trucks.
There are no castings that were used exclusively for 4 bolt main applications.
Almost certainly would be a four bolt main block.
Bore your block .030" oversize and fit it with a 3.875" crankshaft and the appropriate rods and pistons.
You could check the block serial number at mortec.com, but it's probably 4 bolt.
