Just put a beefed up 350 into a friends 92 RS which had a 305 TBI. the 350 is carb. so we rigged the elec fuel pump to turn on with the ign. key and put a regulator on it at 5psi. everything was working fine, well first off we broke the rear end first day we test drove the new motor...got a new 12bolt back there all done yesterday, now the carb is messing up. its like the floats aren't filling up. when we make a turn it stalls out on us like the float is empty.. but i set the floats perfect...you can set them real easy with an elec fuel pump so it barely trickles out the hole. its almost like the fuel pump is going on and off or the regulator is trashed and its just trickeling gas out....
