If you couldn't jet it up rich enough to slow the MPH down in the 1/4 you don't have enough fuel supply I've seen this many, many times in race cars, every body usually under builds the fuel system and never fix it They have enough fuel to as fast as there going until they change the fuel system, there're many gremlins in the fuel system All the way from the fuel filters to the needles and seat sizes and every other part in between the tank and carb. or injection Let us know what you find BTW, my old pump gas Duster, 518 C.I. pump gas Duster, didn't care if it had 3;73 to 4;30 It ended up running high nines through the muffs with the air cleaner on, motor only ![](/ubbthreads/images/graemlins/grin.gif)
