350 Block Question
I was thinking the other day, how nice it was I have a Chevy 350 and I wondered are all the 350 blocks the same? Is anything different over the years or with my 1984?

all were mostly the same from 68-91. some were two bolt main blocks some were 4 bolt mains. in the mid 80's I think they started to cast them in Mexico

Externally no ; internally yes.
If dealing with the late ,large journal engines (>'69),
80 - 85 got the dipstick on pass side , a change was made in '87 to a 1 pce seal crank and roller lifters in most car engines.Most GenI parts will swap '69 - '00 except crank as noted.
2 or 4 bolt mains depending on original application
LT1 is a stand alone block; heads only fit a LT1

A minor variation of the 350 CID small block
(Sorry...
I couldn't resist!
)Just why the 96 GS draws more $$ at auction for essentially a paint job, some "bolt-on" flares, and a VIN over the ZR-1 is a mystery of the ages! Go figure!
