17057253 Rochester question main body air bleeds

<< < (3/3)

Mr.Pontiac:
Will be ordering a carb. Kit from you shortly

Cliff Ruggles:
With a RAIV cam in a 400 build at 10 to 1 compression it's going to like a lot of idle fuel and bypass air.

You'll need to use smaller primary metering rods as well.  Those carbs come with pretty large .049" "K" series rods and 73 jets if memory serves me correctly.

Should have CV secondary rods, those are a good choice for what you are doing...

Mr.Pontiac:
So I did not hurt carb at all by opening up the air bleeds? Yes I’ll get those rods from you.last time I rebuilt one of these carbs you sent me 74 jets.

Cliff Ruggles:
Not at all.  I've built hundreds of those carbs and they are among my favorite for late model custom units that I sold here over the years.

Linkage, available vacuum ports, convert easily to electric choke, front fuel inlet, etc.....

Mr.Pontiac:
Thank you
