I've never run one on a six but ran the stock 32/36 Weber on my 122cid Pinto about 30 years ago. Headers and a 239-239 duration solid cam. No power below 3000, turned about 7000. The Beemers of the day could not stay with that little grocery getter.

Thru the muffler it liked
Primary
50 Idle
132 Jet
190 Bleed

Secondary
65 Idle
160 Jet
180 Bleed

With headers open, I'd change to 135 jet and 160-180 bleed on the primary. Even a Pinto sounds pretty good with open headers at 7000.

The 32/36 should add about 2ftlb and 5hp to your stock 230cid, if not then something seems wrong. I would guess it will be a whole lot better on gas too, the old Rochester 1bbl is not too good in that department. Simple, cheap, easy to rebuild, but not too good on gas.

I'm getting tempted to try this carb on my 250 or 292 Nova.
Might have an issue with hood clearance -

Questions - how tall is the adapter?
How tall is the carb, from base to air cleaner pad?
