I know someone who is looking to get more power from a 350TBI in his chevy pick-up. He's asked me, and I told him the best way would be to perhaps swap to something that's more inline with what he'd like...which he's considering....since he's planning a rebuild of the engine at a minimum (230,000++ miles)

I really don't know what the realistic expectations for a TBI engine...I know many disdain them, but it does appear some do upgrades, from computers (chips?), to cams, headers, rockers, etc....

So he wants to weigh his options and kind of go from there. What can be done for the TBI
