Small Block & Big Block Chevy Specific - Project motor

Looking for a SBC for a project! Wondering if there is a specific truck or car that came with a 4 bolt roller cam 350 with a 1 piece seal. Been searchin but all i can find is info that says it might have a 2or4 bolt or roller/flat tappet,but no specific info on a year or model that def comes with a 4 bolt/roller cam 350??? Any help is greatly appreciated!! :chug:

ok the 1 piece seal is from 87 and up the roller cam blocks are from 87 and up as for a 4 bolt look for a 3/4 ton or 1 ton truck motor most of them are 4 bolt, if you are going to run a mechanical fuel pump make sure you get a block that is capaible of putting one on it most of the vortec 350's 95-00 have the boss for the fuel pump but its not casted into the block no hole for the fuel pump rod, and if you find a good 2 bolt just get it splayed it might be cheaper that paying for a 4 bolt and tons stronger,
