how much horsepower from my 318?

Okay my stock 1968 2 barrel carb 318 made 230 horses...higher compression....by 1977 my 2 barrel 8.5:1 compression ratio made 140 horses...I would guess his 1986 model may not be more than that unless they did something different in trucks and vans.....now my 1969 318 that I built up with a 440/440 lift cam and stock intake manifolds will make 236 horses according to Comp cams software....600 cfm four barrel with a performer intake manifold...headers can a little but combustion ratio and cam really infullence the horses
