hey guys my friend has a 305 thats completly built over and he put it in a older jimmy with a 2 speed powerglide tranny and he is having a problem. He seems to loose fuel pressure when the motor heats up. the only thing is when we hose it down while its running the fuel pressure will go back to normal. we checked everything externally on the motor but it keeps dropping. we checked all the compression on every cylinder and everthing seems to be good. Does anyone have a clue on what the problem could be?


thanx
corey

need a litle more information such as is he using the fuel pump on the motor or the original in tank? also is this a carbed or fuel injected swap?
