I'm looking at buying a 350 for my first engine build. I will end up building it into a 383 or maybe a blower motor(6-71 roots type) .
A local guy has a 84 350 (14010209) mortec says this could be 2 or 4 bolt.
It was in a half ton and the owner swapped it for a 6.2 deisel for towing.
It has 200,000km and has never been rebuilt.
He only wants $150 for the complete motor.
Would this be a good candidate for a performance engine( 400+hp)???
I would like to keep this as budget friendly as possible.

If not what would be THE block to look for ?

Hi,
Any block is kind of a crap shoot. If it came out of a running vehicle you can probably rebuild it. The correct block really depends on how much horsepower you want to make. With the 6-71 you might be better off with an aftermarket block.

If it was running when he pulled it and isn't rusted up, $150 is a good price for a complete rebuildable motor. (especially in CAN $)

He said it's still a running motor....not sure if 2 or 4 bolt mains thou.
I'm just thinking it might be good for a first time build.
Not even sure what i'll put it in.

For a small block with 400-500 hp do you need a 4 bolt?
Or does that only relate to rpm?

400-500hp wouldn't require a 4-bolt, or forged crank. 400ish is well within the range of a streetable 350, but not 500hp. If you really want closer to 500 than 400hp, you should strongly consider a 383, which would be similar in cost and could still use the $150 350 block. Having been there already, I'd strongly recommend forged pistons over cast or hypereutectic.

You'll throw away everything but the block, crank, rods, and sheetmetal.

Realistically, you shouldn't keep the crank and rods; and the sheetmetal may or may not be what you need.



Wait for a '96 Vortec unit; or buy a bare block and go from there.

err......yeah that was an 84....

I shoud have also said this will be 90% street motor.
Closest !/4 mile trak is 21/2 hours away

 

[Eric68]

2 bolts are fine for a street 383 build. Just stud the mains.

I personally would stay away from that block for any Performance build up. Why, blocks are softer in material and light weight casting. The older 1970 to 1974 blocks are a dime a dozen. Look for a 010 casting, this can be either a 2 or 4 bolt block. This is a 350 block and is a heavier casting.

if you're planning on doing a blower motor, i got a bunch of good used performance stuff that would work for you
