    If it is an original engine, you don't need to pull the pan or any other parts. All you need is the engine code stamped on the front of the block ahead of the passenger side cylinder head. Get that number and post it and someone can tell you exactly what that engine started life as.

    anything south of the first cylinder is a date code and tell you nothing about what the application was for that block in 74 . the pad stamp is the key and if its gone treat it like any other " date coded " 350 , unless you can tear it down and find the forged internals . i do believe the L48 did have a 4 bolt main as all 4 bbl 350s had back then . the difference was the forged crank and rods and aluminum pistons in the L82 / Z28 motor . he is really not asking a ton of money for it sooo..

    Found out it was only a L-48, 2 bolt main motor, probably not worth it to buy.
