Want this question answered?
lt1 is a 350
What type of engine is 14093638
Some of the features of the LT1 is that the LT1 has a reverse flow cooling system that first cools the cylinder heads. The LT! also helps maintain lower cylinder temperatures that allows the engine to run at higher compression.
Chevrolet L99 "baby LT1" 4.3 liter 265cid V8 cast Iron heads from a '92-'96 caprice or impala
I was unable to find that exact number at mortec.com, however if you have a set of 3991492's, they are very possibly a set of 70-up LT1 camel hump heads with 64 cc chambers. These would be valuable heads.
53 cc lt1 heads...92-93 good heads for porting
lt1
LT1 has a Opti-Spark distributor, whereas the LS1 is distributor less and has individual coils among other upgrades. Not to mention the cylinder heads on an LS1 were touched by God.
nope
You can tell by the heads. 5.7 has aluminum (silver) 4.3 has steel heads (darker grey or painted black.)
of course
it will fit on any Chevy SMALL BLOCK of the same generation of your LT1
