Jetting for '74 400

[Bob Garner]

I am running a 38mm Bing with a #1 slide with an Ace pipe in Colorado. Any suggestion for jetting, neddle position, etc for 500' to 1500'

I do not know about the jetting,but theACE Pipe got my attention.What is it?Do they make other Penton Pipes.I'm looking for a
pipe for a 77 400.

Try a 195 main. That should get you close. Old or newer style carb dictates needle needed. Questions? Give me a call. days 309 676 0557
