New build 454 mild cam,4 speed using a 650 holley,Dual feed,mechanical secondary,car starts fine and idles nice. When driving it feels like i need more fuel acts a little flat.What carb do most of you run?
I just installed a new Prosystems on my mild 454. I don't even know what size it is & dont care. I filled out the online form then they called me. It was not cheap, but I can say this is by far the best carb I have ever used.
I literally put it on & it runs great. It fired right up. I had to turn down the idle just a little. Then I just turned in the screws on the metering block a little to clean it up. I highly reccomend this company. Good Luck.
The only time this hurt me is when I had to pay for it, but well worth it.
