I just bought one of these carbs and a Performer RPM for my stock 302. I found out it's a 450 cfm factory replacement carb. Has anyone used one and how was it?
I got one, last ran on a stock '66 390... Had outstanding off idle throttle response but was a little small for that application... On a stockish 289/302 they are fine, the orig Autolite 4100 were 470cfm...
