yes, iron block w/ aluminum heads.... ls1 has aluminum block and aluminum heads
53 cc lt1 heads...92-93 good heads for porting
You can tell by the heads. 5.7 has aluminum (silver) 4.3 has steel heads (darker grey or painted black.)
The GM F Body LT1 cars got the 2 bolt mains. Only the Corvette LT1 got the 4 bolt mains with aluminum heads.

lt1 is a 350
its the LT1 don't confuse with the LT-1 from the oldschool corvettes because there not the same. its a high compression reverse cooled 350 with aluminum heads
nope
Heads do not have to be ground because they are aluminum. If you're taking both heads off then you need 2 new gaskets. It's not a bad Idea to replace both if one is leaking though because the other one might not be far behind.
of course
it will fit on any Chevy SMALL BLOCK of the same generation of your LT1
no
