Boo's got it right, sorry to hear about the 5200 though. I have a 63 with a 292 and I played with the Rochester one barrel and replaced it with a Monojet. Didn't get as much performance increase as I did dropping in an HEI and playing with the advance. Still not much, got 11 mpg. Carefull though on the advance curve, best have a shop set it up to match the original dizzy.
Boo any comments on mileage between the 1, 2, and 4.
Thanks, Larry
