Needing more fuel

1bigwilliestyle · Sep 21, 2017

I need some help and or advice. I have an old 94 K2500 4x4 that needs a new power plant. I have a vortec headed 406 that I want to put in place of 300K mile 350. I need to know what is best option for fueling this bad boy? Was originally thinking of Holley TBI as it is physically big enough to some what support this engine and is a direct replacement. thx

After having messed with stock GM TBI and the holley 2bbl units i would go with your favorite brand of 4bbl TBI units such as fitech or holley's sniper system. But if i had unrestrained resources i would use a fully sequential port injection system. Nothing wrong with GM's TBI, but with 406 cubes, vortec heads and whatever else you may have done, it would be very difficult to get it to run well with a 94 TBI computer. To do it right on GM's TBI you'll need an ECM from the latter model trucks at the least and soon you'll have spent more than a standalone 4bbl TBI unit. (Unless of course you already have the capability and know how to tune EFI.)

Resources are limited, I really like the FiTech, but not sure if I can get it to work with the rest of the truck. I drive this truck daily in the winter and it pulls car trailer in summer.
