Building a better Lo5

[90K1/2ton]

I've been brainstorming some ideas for when my engine needs rebuilt. I intend to have the shortblock/bottom end rebuilt, for I don't plan on racing or doing much towing. After reading countless threads, I've come to the conclusion that vortec heads and a LT1 cam are both very popular upgrades for the Lo5. They also seem to be reasonably priced. I also like the idea of using GM parts. I don't not know how to tune TBI chips nor do I personally know anyone who does. I do know that far more people are familiar with tuning carbureted engines. I also like the simplicity of a carburetor so it is very likely that is the route I will take. What carburetor/intake combo would best suit my setup? Truck will primarily be used as a fair weather vehicle that I may use for towing from time to time. I am hoping to be somewhere in the ball park of 300hp/400tq. Something that can keep up the trucks on the lot today.

Truck is a 90 K1500 with an Lo5, 5lm60, NP241 and 3.73 gears.


Thank you!

Eric

You might get better response in the regular engine thread instead of the 96+ thread. The b-body lt1 cam is the same as a vortec truck cam so essentially you are building a vortec long block. Easy build.
