5.7L Vortec swap to TBI

[Thatlowchevy]

So, we have this nice 1998 Silverado ECSB with the 5.7L Vortec in it. Recently this truck has had some issues with fuel and cooling and acceleration (as per my other threads) come to find out it is a cracked head and intake manifold. What i want to do is take a TBI intake and heads and put on this truck so it'll run right again. What is the easiest way to do so? I have a complete 1995 Silverado parts truck with the TBI and computer and such. What is the absolute necessary wires to make the TBI system function properly? and help is greatly appreciated

I personally would avoid the tbi setup and find some replacement vortec stuff

that's what i was thinking, but i can't find anyone with another intake manifold

Do you need an upper or lower? What is wrong with the intake?

I have nothing against TBI (I'm happy with mine, actually) but you're going to be better off replacing the Vortec parts in your truck than trying to swap in an inferior system. If it's working properly, the Vortec system is superior in terms of performance and gas mileage.

I need the Lower, i improperly torqued the bolts on install and shattered one side right across the water jacket so it leaked coolant all over when the motor got hot

The Lower, it broke across the water jacket
