You said "quick and simple" and "from a performance standpoint". You said nothing about a budget, or what aplication. A 3-2 bbl Webber setup will set you back over a grand. Time for a reallity check.
Yeah, I hear you. I figured I could scoop up the intake and get a Weber carb every now and then as my wallet permitted or I could spend around $200 for a used Clifford on ebay. This engine is getting done right if it takes me a decade.
I probably should have mentioned that my Valiant is my dd, too.
