this is the # that was on the block right under the GM stamp 3970014

also on the valve cover it has a sticker with PT NO 330576

 

it has a two bolt main with a orange painted block also it had a 4 barral carb on it

it was pulled out of a Chevy work truck it was used for some company and the year was just starting it started to blow smoke so the guy said put a new one in and left the engine

 

the engine that went back in was a 350

 

price is 50 bucks

 

any info on this engine?

 

thanks

it says two bolt or four

 

does that mean anything? or did that block # come in both 2 and 4 bolt

 

does this engine sound like a winner for 50 bucks? or keep looking for a another one

Two or four bolt will work ok, used block is good as its been heated and stressed etc. Long as it checks out (have it magnafluxed and checked for cracks at a machine shop) then it sounds like a good core block to start with. How much horsepower are you looking to build? That would be the question if 2 or 4 bolt main would be preferable, and even that is debatable, but for a moderate street engine 2 bolt should be fine. Use good ARP bolts and you should'nt have any problems with it. My opinion anyway, your mileage will vary, void where prohibited by law.

 

Good luck,

Even if you decide your HP is more than a 2 bolt can handle you can always have the machine shop put on splayed caps as they are stronger than a regular 4 bolt anyway.
