93 5.7 350 corvette motor

What extra stuff would i need to put a 93 corvette 350 in a 93 gmc sierra because i can get one cheaper and it will give me more power.

Lots of expensive stuff.

Computer.

Is the Corvette motor TBI or MFI? For MFI, you'll need fuel pump and system capable of the higher pressures.

Auto or standard transmission? The auto will have to be programmed for the new motor/torque converter combo.

 

Your best bet is a TBI direct replacement.

It's not a bad swap. I've done a few of the swaps. If you were to purchase it, be sure to get the wiring harness and computer with the engine. The '93 'Vette had an LT1 which is fuel injected so you will need the correct fuel pump. The exhaust ports are also different on the LT1 heads; the bolt holes are in a different position relative to the port opening. This means you can't use your stock manifolds or headers made for a gen 1 SBC. You will need to either use the LT1 manifolds or headers made specifically for the LT1 engine. Aside from that it's a bolt in deal.

 

In '93 the transmissions were still controlled via a detent cable. No fancy electronics required.

So is it worth the money for the extra power?

And what cheaper extras could i do to the lt1 to get me more power?
