I loathe holley carbs, never had good luck with them. had a 600cfm on my old 79F100 with a stock 302. 2 weeks after rebuilding it, the float hung up and basically flooded the engine, and upon trying to restart, it caught the engine on fire big enough that the vacuum wouldn't pull the flames in.... only thing I had to put it out was my fresh cup of coffee.....
what a waste of coffee......
