I need a new engine so looking for crate engine. Its a 24 year old truck so I'm planning on replacing everything. Like to find a short block and throw on aluminum heads but as usual, money is an issue. I dont have the time to rebuild this one. I was a HE mechanic for 24 years but I didn't work on gassers to much.

Wife wants to make it a dune truck and as a back up daily driver. Looking for a mild build.

Easier for just a crate engine and tuner or intake, exhaust cam, etc?

I dont want to spend 10grand on an engine but 3-4k isn't out of reach.
