big block fuelie idea - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Blackhawkdc · 09-13-2003, 05:17 PM

anyone ever thought about this? Take the upper and lower intake and throttle body from a '95 or newer 454 in a GM truck. Polish the heck out of the intake runners, bolt on an oversized throttle body. bigger injectors and a stand-along fuel control system. I've been thinking of unique ways to put fuel injection on my big block 496 stroker when I build it and install it in the truck. The fuel injection system has to have 8 injectors and be able to handle 550+ horse. Any other ideas?

Other than what you mentioned...there are several F.I systems out there as a bolt on/in unit....Holley makes one and few others...I am sure street and performance does too.

I wouldent mess with stock stuff you can buy a kit or peice it together you can buy the injector bungs and weld them into an intake and then get a throtle body, injectors, fuel rails and computer and harness from accel. Just a thought.

You are going to need an aftermarket ECU which are not cheap. I am deciding whether to carb or EFI my next engine. If I go efi it will use an aftermarket ecu with custom rails/intake and a 4 barrel TB like GMCJunkietwo suggested. I also HIGHLY suggest you break in an engine with a carb, then go to EFI unless you are an efi tuning god. Your engine will thank you for it. I have spent a LOT of time tuning with a FAST ecu and gotta admit its just plain cool. $1800usd for the ecu though. And the O2 sensor is about $450usd if it fails (has to be matched to the ECU). THats the only part I dont like about it.
