2 ways. Pull your dipstick and see if it looks like a dirty milkshake (which is blown head gasket to the oil side and is much more common). The 2nd is look for bubbles in your radiator when its running. Couple the "Jacuzzi" with unexplained loss of coolant AND varying engine temps would be a very good indicator of the Combustion side of the Head Gasket failing (less common). You can also get a Coolant Analizer to check for Co2 which is pretty much a guarantee.
lt1 is a 350
nope
You can tell by the heads. 5.7 has aluminum (silver) 4.3 has steel heads (darker grey or painted black.)
of course
The aluminum heads with the code number 10128374 are cylinder heads manufactured by GM Performance Parts. They are designed for small-block Chevy engines and feature improved airflow and performance compared to stock cast iron heads. These heads are commonly used in high-performance build-ups for cars and trucks.
it will fit on any Chevy SMALL BLOCK of the same generation of your LT1
no
no
1971 chev truck/corvette/lt1
yes, iron block w/ aluminum heads.... ls1 has aluminum block and aluminum heads
YES!There won't be any gains from doing it, but it will fit. The only difference is the Corvette has aluminum heads, where as the Caprice has iron heads. Stock for stock the iron heads flow better. Unless the engine is blown or missing there is no reason to do this.Just a side note.....Vette Lt1s had 4 bolt mains and the F/B bodies had 2 bolt mains. Something to consider if you gonna build it
The GM F Body LT1 cars got the 2 bolt mains. Only the Corvette LT1 got the 4 bolt mains with aluminum heads.
