Running Lean - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Alright I have a 72 that I bought that has a 94 - 350 motor that has been converted to TBI. I have had it to a couple of friends places trying to find out why in the world this thing is running lean. I have changed the fuel pump to meet the PSI req of the TBI, changed fuel lines. The computer was calibrated for the TBI from the company purchased from. I am wondering if anyone here has seen this problem before??

Thanks.

Joel

Where did the injectors come from if they are off a smaller motor i would think that could cause a lean problem .. Maybe a clogged fuel filter...
