casting number help on sbc
Im looking at buying this engine and want to verify it is a 350.
the casting number that would be the driver side right by where the bellhousing meets is 57lgsg1 and the other is on the back of the engine right by the freeze plug and its h10627638. i also was wondering if it was a 2 bolt or 4 bolt. supposed to be out of an 89 chevy truck. thanks in advance jason |
Re: casting number help on sbc
I can't match your numbers up to anything. The casting number should be by the bell housing and should be six or seven numbers with out letters. You should also have a engine suffix code stamped on a block pad located immediately forward of the right hand or passenger side cylinder head. The entire engine code contains the assembly plant, month and day. Your suffix code should have a letter, four numbers and two or three letters at the end. Here are the casting codes for small blocks.............

Re: casting number help on sbc
i tried them too with no luck. the only thing i have found is googling the 57**** number and there was one thread of a guy trying to find the same thing, but the link was gone.
