are the rotating assembly's from either place good??? anyone running one? I'm looking at a cheap one (the 379.99 one) in the midwest catalog to build a back up short block with... and if you can give me suggestions of anyone else that is just as cheap let me know... lets hear some opinions

This goes back to the old saying what you paid for is what you got. The more you spend noramlly means the better the parts you purchased. There are some places that charge a lot for cheap parts but not too many. If the parts you are getting are forged then you are good to go. I don't recommend anything less in the bottom-end than forged rods, crankshaft, and pistons.

okay,
Joe

In July of this year, I drove from Florida to JR Motorsports in Iowa to purchase a used Sprint trailer. It was if anything undersold to me - meaning they made sure I knew about every little scratch and dent before the trip. I really got a better piece then I expected.

While there, I was given a tour of the place, engine shop included. My impression was very favorable from what I saw - they have a good staff and a fine facility.

Here's how I look at it.

Just about any new part (1998 & up), even if made by a 12 year old in Malaysia is probably better built/designed than the 'performance' factory parts of the 60's and 70's. With proper attention to detail, even a budget motor with overseas parts will work quite well if in it's intended application. Meaning, if it's run in a stock or emod spinning less than 7000 and making under 500hp, chanes are it'll live a long and healthy life.

I worked in an engine shop for 3 years (95-98) and got to see all kinds of stuff. I've seen guys spend $15k on parts to get their behinds handed to them by someone that spend $2500. I've also seen $10k motors yack their guts all over the place where a $5k motor lasted all year.

I guess the point is that even the best parts can be turned to scrap if not assmebled properly. And scrap parts can live a long time if assembled perfectly.

I but parst from them every year and everything has worked as it should have. As a matter of fact I ran one of thier cranks(cheap one) for two years in a row and never had a problem.

I bought a 355 shortblock from them. I've got about 15 nights on it. So far so good.
My advice, don't buy a $1500 short block expecting it to turn 7500rpm+ all day long and last. There are some of those types out there. And then they blame the poor engine builder or the machinist. Geez.
