Engine swap 95 k2500 5 speed.

[KaydenMorlan]

I have a 95 GMC K2500 5 speed with the 350 TBI and manual Tcase which I believe is the NP241 and the 5 speed I know is an NV4500. I don't think it's got the granny gear but I don't know for sure. It also has a 3.73 Posi. Good running truck for me, but you can't get much power out of a tbi. So before I dump money in it, I want others opinions for what's best. I am selling my '91 Corvette and using that money for my truck. I am wondering what you guys think is the best swap out there without having to do too much work, and being able to retain my current trans, tcase etc. I don't have the funds to swap those, so what's the best out there? I was thinking of doing a built 383 tpi build, or a 383 LT1 build just because what I currently have, would bolt to the block of both of those. What I really want to do is a Dmax LBZ swap but money is a playing factor in this. I guess the numbers I want to make are 350 plus HP and around 400 torque. I want to know prices etc. I could really use the help, thhank you.

Probably the easiest swap (technically) would be a crate big block with a carb and a simple electronic ignition. You'd get gobs of torque easily, but the side effect would be terrible fuel economy.

Any serious hp and torque with decent economy is going to require a new injection system and management. I still think a crate motor would be the way to go. They can make them cheaper than I can build them these days.
