Re: Carb advice wanted

In theory a 650 might be too big but stock 350’s came with 750 cfm quadrajets.
While that 300 bucks might seem like a bargain there are always extra costs with eddy carbs.
You might need a heat spacer. 40 bucks.
An adaptor to put a squarebore carb on a spreadbore intake. 20 to 40 more.
Possibly a fuel regulator. Eddy carbs don’t like more than 5 psi. Another 50 bucks.
Now you’re up into the 450 to 500 range.
A well built quadrajet can be had for 350 bucks and needs no extras. Even a Holley 600 would fit the bill.
What carb you got now?
