The block, itself, for the LT-1 in 70, was nothing special, other than a 4 bolt main cap. Now, the serial numbers, and casting date will be different, and will eliminate any "numbers matching" type of thing, but, other than that, if the 76 is a four bolt main, then yeah, they are the same.
lt1 is a 350
350 Ls1 or 350 lt1 but the Lt1 has a cast iron block and the ls1 have a all aluminum block there fore the ls1 block is lighter. "but the make the same horsepower
no
it should that would make an lt1 302 like the old z28 camaros ABOVE ANSWER IS WRONG The block is the same. The displacement of the 4.3 (L99)is different because it is de-stroked. The pistons and rotating assembly will bolt in the same as a 350 block. LT1s have little to do with the 305, aside from the external dimenstions the heads are also essentially the same but may requirew portwork to equal the lt1
it will fit on any Chevy SMALL BLOCK of the same generation of your LT1
LT1 gen 2 to LS1 gen 3 no
A real LT-1 had a four bolt main block.
Yes as long as the intake is not off of an LT1.. The intake in an LT1 350 is for a reverse cooling engine and doesn't have the same coolant passages, as well as not having a hole for the distributor.. LT1 used Opti-spark..
Yes it is a small block and NOT an LT1 engine. 5.7L is a 350 engine.
lt1
1,8,4,3,6,5,7,2.
will a 1995 Chevy 350 lt1 motor work in a 1990 Chevy pick up
