Carb Problem
I have a Speed Demon, #1402010, which is suppose to be a 750 cfm. When I put it on my street 454 and it seemed to drown it with fuel. I then switched to a Holley 650 cfm and it runs better. But I thought I'd get more power with the 750. Any suggestions? Here is my engine run down:
454 block
forged pistons - 10.75:1 compression
new chromoly rings
cam - .544 lift
roller rockers
rebuilt open chambered heads
Weiand aluminum intake
Mallory distributor
Stock mechanical fuel pump
