I am new to the sight, and I acquired these two engines 20 years ago and I was told they are 482 turbo marine engines. I searched the internet for the casting numbers for the blocks and cranks, but I can find no info. I was hoping someone here has some info on them. The casting number on the blocks are 0319192, casting date of D-9-9, Tonawanda build dates are T0604 0 and T0507 N. Crankshaft casting number is 0-250157 with $ cast into one of the counterweights and is a 4.25" stroke. Connecting rods appear to be Can-Am 6.405 with floating piston pins. Both engines are standard bore 4.25" and crank and rods appear to never have been rebuilt as the one I took apart still has the original GM bearings. I sure would appreciate any info someone might have and thank you very much.

Call me i had a few of them .
