The original 350 in my truck was blown to hell and back and I have a racecar 350 engine my grandfather had in his racecar that's seen better days, it's rusted and where it's not rusted it's gunked up including the oil and water gallys. All I have of it left is the block, and heads. But I could pick up a pretty good full used vortec for less than a 800$. I would like to use my th350 with the transfer case. I'm trying to make this build as cheap as I can make it because I know it'll be a pretty penny to get everything Right so I'd like to make it all as cheap as possible.

I plan on eventually vortec swapping it anyways and putting the 350 in a racecar but I feel I'm losing my want to finish the project and if I maybe have a win and Get it moving I may be more inclined to get it going even more so whatever is the cheapest im willing

Since cheap is the goal , prolly best to rebuild what you already have AND since you may feel like "losing want", swapping to a vortex is a P.I.T.A. laying in wait. An expensive P.I.T.A. at that.

If / when you get her running again, that may re-invigorate some of your desires.

Others nay have different opinions but that is mine.

What about Bob? Baby steps.

yeh what Rusty said. Save the LS for later and if your afraid of wiring, just put a cam and a carb in/on the LS.

Don’t get confused. Swapping in a 350 with Vortec heads is much simpler and cheaper than an LS swap. You definitely need a Vortec intake manifold and most likely an electric fuel pump (very few 350 Vortec blocks are machined for a mechanical pump). There are also other odds and ends needed, but overall it should just drop in as a replacement, and bolt right to your TH350 (you will need a flywheel for a one piece rear main seal).

It’s also fairly common for Vortec iron heads to be cracked by overheating, so the heads need to be checked by a machine shop. However, the Vortec 350’s higher compression, good flowing 64 cc heads, and roller cam are all big improvements from your old 350. You can put together a reliable 325-350 hp engine with simple bolt-ons.
