    Having done this swap before, 305 injectors on this 305 would be BAD. Mine ran best on the stock 350 chip and 350 injectors. Had to correct the BPW in the chip and rework the VE table to make it run best. Also had to give it about 10* initial at the distributor.

    I had a Mellings MTC1 204/214 @ .050, .420/.442" lift, 112 LSA, 107 ICL in my 1983 G20s stock 305 with a 92 350 TBI intake, TBI, exhaust manifolds and exhaust system.

    The stock 305 injectors and stock chip are so lean even at 16 psi (the highest I could get the stock pump to output) it was too lean to be driveable.
