Drop the oil pan, remove thrust bearing cap, loosen all the mains, use a screwdriver to push the old main seal out a little, then use the new seal to push out the old seal the rest of the way.
You will need to remove the transmission.
Need to know the year of engine.
400, about.
It is a small block Chevy 350 engine with 6 bolt main caps.
From the oil pump, through the block to the first main, then through the journal to the rods, then through the journal to the next main, ect.
No. You would need to have the main journals turned down .200". Then it would fit.
Yes, the only small block Chevy flywheel that doesn't interchange is the small block 400 ci.
"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).
it was a waste of time and money. it was the only small block in its generation that was externally balanced and had different size main and piston journals.
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 is no such thing as a small block or big block Pontiac. Outside dimensions are all the same from the 326 all the way up to the 455. The only real difference in the blocks is the size of the mains. The 326-400 run a 3" main...while the 421-455 run a 3.25" main. If you are "comparing" it to say a small and big block Chevy.....dimensionally it falls in the middle.
