Your going to have to bore it and with a 283 you can go 125 thousands. That will give you a 301. They were real popular in the early 70's. pretty much what the first S 28 motors were.

bore it 060,use a 600 cfm carb.If its a hot rod then a 600/650 double pumper works well with matching speed equipment.If its going to be close to stock then use a 550/600 Vs.

It would be cheaper and make more power if you buy a complete 350 vortec engine from a 1996 to 2000. Then get a vortec intake and holley carb and drop it in.

These engine are cheap, have roller cams, and vortec heads. It most cases you can drop them right in. Should be able get one for 500.00. Make sure to get a complete engine (fan to flywheel) as the little stuff will nickel and dime you to death.

The only problem is these blocks don't accept a mechanical fuel pump.

not ALL blocks will go .125" overbore (the magical 301). And even when they did go that far, theres no room for clean up, so when its tired, its done. I'd go .060". Have it magnifluxed and sonic checked before you get too deep in it. there isn't a lot out there for piston selection at a cost effective level anymore, and you'll want to watch your head and cam selection with a small engine. Also, you'll probably want to plug the road draft tube and use a PCV system - there are ways you hide them fairly well in plain sight.
