ok well to make a long story shot this has been driving me up a wall. I got a 94 chevy with tbi i i had a 350 in it but sadly it spun a bearing so i had a 30 over stroked 305 sitting around with 20k miles on it so i decided to swap it i had to change the heads and intake manifold to take my tbi so im running it with 350 heads i changed out the injectors and the chip over to 305 specs and the damn thing is running rich as hell and smokeing away deffinitly fuel not oil or coolant ran compression tests on all systems coolant and block no changes on anything so i know theres no leaks but i still cant find the problem if anyone can help out please let me know thanx
