That engine isn't a lt1 it is a gm goodwrench crate 350 with 2 or 4 bolt mains made in Mexico. I have the same engine in my astro van and i have heard that they make 250 hp and 350 ft/lbs of torque out of the crate.
No,its not an LT1 as they are aH.P.engine built from 1970/1972.It is a Goodwrench crate engine,very common aftermarket.The casting 10066036 is known as the LM1,which was manufactured until 1988,the crate engine comes in many variations,but it is a 4 bolt main,2 peice rear.No matter what! it is an excellent motor low end.I run mine stock with 650marine Holley,sag,manifold,250/270 as it is.
lt1
Your casting number is listed at this address: http://www.mortec.com/castnum.htm. It is a targetmaster crate motor and can be used as a replacement for many oem applications.
If your spark plug wires go to the front of the motor and behind the water pump, 99.9% chance its an LT1 (if you're talking the newer LT1. The Older one from the 60's you'd have to run the block numbers)
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.
What type of engine is 14093638
lt1 is a 350
it will fit on any Chevy SMALL BLOCK of the same generation of your LT1
An LT1 will fit into any car that a Small Block Chevy fit's into.

Regardless of the block, you have to use Vortec heads to use a Vortec intake.
