421
Ive been looking at this 421 engine from white performance to put in my s10. Just wondering if anyone has bought one of their engines or know anyone that has. This seems like a pretty good buy for 6950.00. It is fully forged and uses a bowtie block, with dart pro1 heads.

Not trying to be a dick or anything, but I ordered a 396 rotating assembly from Eagle that came with King Main Bearings and my engine builder said to get those bearings out of his shop.
On that ebay ad they say, "KING MAIN AND ROD BEARINGS HP SERIES, THE BEST BEARINGS IN THE WORLD! THATS ALL WE HAVE EVER USED AT OUR SHOP."
Also they say they test run every engine but don't dyno it.
"Comp cams are not even a consideration for us." Hmm don't really agree with that.
"This engine has a one year warranty unlimited mileage." That is good though if it is true.
That guy has enough of a rep on ebay though that you're probably going to be just fine.
They don't really mention specifics on a lot of things, the guy writes pages of stuff that doesn't really matter about the engine, I would rather read about what brand head gasket, or how far in the hole is the piston, or if I get a build sheet.
1500 heads
1500 block
1500 rotating assembly
500 machine work
750 valve train, gaskets, seals, oil pump, pan, timing cover, balancer, flexplate, manifold, timing chain
I made a list to try and see a rough estimate of what it cost for them to make it, I'm guessing they make around a $750-1000 per motor.

Building a 3.875 stroke 600 horse engine with 2 bolt mains that really does not add up!!!
When GM was selling those 2 bolt Bowtie blocks they were only rated at 375 horse. Those blocks are non priority oiling!!!
By the time you buy that block add splayed caps you can buy a Dart SHP block all machined for 1795.00
He's a good salesman thats for sure.

Are you the guy off speedtalk? You're pretty good at spotting crappy blocks.
My machinist said he saw one of those up in Southern Missouri, so I guess people are buying them.

Crap man, I didn't even look at the picture I looked up a price on a 4-Bolt Bowtie, which I overestimated a bit on that. Aftermarket I wouldn't buy a two bolt main block.

I still have one of those chinese blocks and can't seem to give it away as it has to many issues I guess.
I guess PBM stopped selling them and now offer the World blocks only to find out World does not even machine their own blocks and they are machined by Royal Oak boring in Michigan. Thats probably why we could never send a defective block back to World because what would they do with it!!!

I always enjoy reading your posts and like your signature, I end up flow testing heads and dynoing engines mostly for my knowledge but sometimes to prove a point. People really don't like being called a liar.
