i had a 235 once with 1 carb but someone had put a racing cam in it it ran smooth with a ton of power when you steped on it but the idle was lopey like the choke was on a little i wanted to put a stock one back in but the balancer would not come off it did give it more snap but with a truck 4 speed you realy couldnt use it mayby with an automatic it would work better or higher gears
