Make racing truck help?!!use corvette engine?

I recently bought a truck and was wanting to make it a monster on the road.right now it has a 305 but it truck engine and tranny so its built for torque...not speed.thing hesitates to go over 100.it is a 95 seirra 1500 5.0L.i was wandering if i could get like a 70-80 camaro or corvette or whatever as a donor car with bigger engine and tranny.the reason i want an older car is so i dont got to deal with all the computers.right now with the truck im limited what i could do unless i want to switch all the computers out too which would get expensive and alot of work.so if i get 70s or 80s donor car could it just scrap most computer currently in truck? Even changing my current tbi system in truck to carbs would be a hassle with the tbi hook ups...so would a old donor car work?thanks!

    Power was coming back by the mid 90's. The worst period for power was the late 70's and early 80's so about the best you would find there would be a 350 and I would bet a typical 80's 350 with a carb won't perform any better than your EFI 305 so it would be a lot of work for nothing. Also most of that era would have either the basically the same overdrive transmission or the 3 speed version. The 1/2 and some 3/4 ton trucks and the same transmissions. To get a more HD trans you have to look earlier 70's or the heavy 3/4 or 1 ton trucks.

    i can't imagine how it would pass emissions inspection if you did what you're suggesting.

    yes, there are a few states that do not have emissions inspection. if you're in one of those, i think you want to limit choices to vehicles that have approximately same weight as the truck -- and after such a refit, refuse to use the truck for hauling anything lest you tear up the replacement tranny.
