i have a 4.3 that i pulled out of a 94 chevy 1500. i plan im puting it in my 85 toyota pickup. well i put the motor in the shop and got it balanced, line board, punched 30, light weight pistions/ 10.5:1 compression, high rev springs, polished heads, double roller, chrome-oly berrings, gona run royal purple oil, intake, exhaust, full msd. anyone know what there talking about (actully) and mught know a ballpark what that motor is going to put out?
Should run pretty good but i guess you ownt know until it's dynoed, and as the other poster stated you probably could have made more power with a bigger engine but if u wanted to you would have got the bigger engine right?

probably a pretty close estimate would be to find someone who has the same parts in a 350 smallblock (same cam size and compression, similiar heads, ect.) and just multiply the total power from the 350 by 3/4. it probably will give a ballpark estimate, since the 4.3 is just a 350 with the front two cylinders chopped off. same bore, stroke, just a shorter block, but other than that the same dimensions.
4.3 hp with machine work?
