Re: which hvh carb spacer do i need
HVH is the way to go. I would use aluminum in a marine application for USCG rules. Wood or plastic in the fuel track may not go over well if the boat was to catch fire.
Spacers "tune" the length of the intake track. Air moves in pulses, these pulse have length. Each engine will require a different length for maximized tuning.
The HVH spacer was OUTLAWED in NASCAR in the early 80's after a win by Petty I believe. So we can all assume it works very very good.

I just had Mesa Balancing work over a 800 Holley and they recommended the 1.5 " Wilson Manifolds tapered spacer.
I'm sure they all work and have seen some good results posted with the HVH.
Just more info...

Should work great.
He ran over to Wilson's Tuesday and picked one up and stuck it in the box with the carb for me.
Keep us posted how you run after the work

I realize and fully agree that they are mainly a tuning tool but what about the heat?? I plan to purchase a new tapered/blended spacer but am still unsure as to which direction to go.....Canton, HVH ,Wilson and others. Any comments? Please!!
