you would need a non cvcc carb and intake. or youd have to modify the cvcc manifold flange to bypass the cvcc. youd need an electric fuel pump too, theres no cam lobe for the pump. some fuel line, wiring for the pump, and new gaskets are the only other things i can think of.

What carbs are non-cvcc? (What's that stand for? Sorry- newbie here). If I have the DX manifold, Si block/heads, and HF carb, what will I need to do to make this all work? Thanks, Mark W.

cvcc = compound vortex controlled combustion

non-cvcc carbs include zc carbs (rare), canadian dx carbs, and i believe older accord carbs are non-cvcc

The entire tool selection at Sears or the contents of a Snap-On truck will do you no good if you do not know how to use them.
