Do you have a link?
$1500 seems suspiciously cheap for a quality 331 shortblock.

On paper it looks decent but you never know. Its also balanced to 28oz so you'll have to get a new balancer and flywheel if your going to run it in anything newer than an 81 car.

not bad...balanced, forged slugs etc etc.
What is the core cost and shipping on that? They can kill your "deal" there.

So then only a two piece rear main seal on them??

You will need a 28 oz balancer and flywheel, remember.

I dont have any motors for sale, sorry.
There are a few people (JohnB, etc) on there that can and will build you a quality shortblock.
I don't do side work for anyone on here, anymore.
Sorry.

Retail on the Crankshaft is $217 Retail on the rods: $225 Retail on similar pistons: Under $300 Rings & bearings: $175 or less
That's $917 retail & I know of kits with 2618 forged pistons that retail for $899. Any way you slice it you're looking at around $900 RETAIL for the rotating assembly. Figure any good machine shop will have much better pricing (at least 20% less) & you're looking at cost of around $700. Add a block & machine work & yes it's very possible that a machine shop can do all the operations listed, balance, & assemble the shortblock & still make a decent profit while keeping the machining/assembly quality high.....even if the parts themselves are 'economy'.
From my experience a cast-steel stroker crankshaft & 'SIR' style rods will hold more power than the stock block can handle. The pistons would not be my choice considering the dirt-cheap pricing of Probe's 2618 forgings, but hey...I'm sure they'll still much stronger than the stock 302 slugs which have been known to handle well over 500hp.
Honestly, it's a damn good price. I know I wouldn't buy one....but I'm an engine builder & if I'm gonna do it, I'm gonna spend a little more $$$ & do it right. However, I see no reason why this motor can not handle 450+HP if the machining/assembly was done correctly. In the end the rotating assembly can handle more Power than the block.
Personally I'd go for a 347. Same price as a 331 & you can't go wrong with more cubes IMO.
