1982 El Camino motor swapped

[Chrisj909]

Hey guys im new to this forum and I'm glad to be a part of it. Have a few projects I'd like to use your help on for now I bought my 16 year old his first car.. 1982 El camino, they did a swap on car and installed a SBC 350 in it with a mild cam, intake, headers and 4 barrel carb. Trying to get specific on what the motor came out of. The casting number on the back tells me it's a 87-95 but I can't find any info using the suffix code, can anyone help me out. Its a V0129UMA.. I appreciate the help
