289 Head question

but if you want very good hp gains - a manifold/carb swap by itself is not going to be worthwhile imo
save up a little bit and change the cam (and get headers)

Even going from a stock 2bbl to a 4bbl and aftermarket intake? The seems like a big improvement. I have never driven nor owned a 2bbl(and then swapped to 4bbl), so I'm curous. My current '68 is a two barrel, but its never going to be driven before I have a Holley 600 on there.

if everything else on the motor is stock, it will only make a minor difference...

The difference between a standard 65 "C" code 2V and "A" code 4V 289 was 25 HP (225 vs. 200). Only differerence is intake and carb. Same camshaft.
