228K on this 5.0L Chevy engine and its showing age and fatigue. What is the best way to go?

Lots of ways to slice that onion. I'm at the end of the process of going from TBI head 350 to vortec head TBI 350 and even that had it's share of complications.

I don't know what all will change going 305 to 350. Probably a hell of a lot more.

If I was going to spend the money I'd pick up a 350 or even a 400 and build that. The 350 will be the same cost or maybe even cheaper to build. Source a core from a you-pull yard and it's only a couple hundred bucks. Just make sure it's one marked R/D before you pull. And it can come out of almost anything with a TBI on it.

In fact I have a core out on a pallet I'd sell for $100, like 130K on it and ran when pulled, but it's in New York. From a '95. Whatever is on it stays on it, I took the intake off to use in another van and never did so that could go with it.


On a 93 there's not a lot of difference there as far as brackets and so on, but you may need to find a computer for a 350 or have the chip reflashed.

I'd go with a 350 if faced with the choice of rebuilding a 305. Nearly the same cost, but 350 is going to give you a bump in power. I went with a 305 for my 82, but I sourced a running motor off a friend for $100 so I couldn't pass up that deal. Nothing wrong with a 305, but if you're going to spend near the same money, might as well increase cubes.
