Flat tappet cam in Roller block

Helping a buddy put together a 350 sbc circle track engine using 882 iron heads.. He has an 87-95 1 piece crank and roller block and rules mandat that we use a flat tappet cam. The block is drilled for a mechanical fuel pump so we are good there. Im alittle unclear on a couple of things... Do we use a timing set for a 2 piece block, what timing cover early or late? I know we need to use a late flex plate, what about the balancer early late? Anything else I need to know? thanks in advance

The factory roller blocks put in trucks almost always have flat tappet cams.

You use the regular SBC timing set, just like would have been used before '88. In '87 they had a one-piece rear seal and no roller cams, so the one piece seal is not of importance here.

Use whatever you want for a timing cover. Your late one would be fine.

For the balancer use whatever you want, these weren't unique to the engine.

Basically all you are doing is just eliminating the cam retainer plate, dropping on a standard timing chain of your choice, and throwing in a good old fashion flat tappet cam. There isn't really much magic going on here, or anything the factory didn't do themselves.
