I am shopping around for a 383 kit and found a site http://www.speedwaymotors.com/p/3176...ssemblies.html which has their economy rotating assemblies. I was wondering if anyone has had any experience with these people or their products. I tried to call for more info, but the lady didnt know too much about this.

I've looked at speedways kits too. and wondered about the quality and cause I go to Lincoln NE. once or twice as month, witch makes for no shipping costs. (looks like the kits use KB pistons) but this round, I've got about everything for a roller vortec headed 350 build.

Well i've done some more looking around and found this kit http://shop.enginekits.com/osb/itemdetails.cfm?ID=81. It seems like it is all known and quality brands at a very good price. Any suggestions?

I found this site the cheapest but after balancing it was more expensive than Jegs.

Stay away from powerhouse kits, a friend of mine ordered one awhile back and it was junk. Poor machining, improper balance, and the first kit he recieved we had to return because is was covered with corrosion-rust! It was Crapola

The Speedway economy rotating assemblies use claimer pistons, which are KB Hypereutectic pistons, reconditioned factory forged rods with good bolts, and new cast crank. The balancing is a recommended option on them.

You could use that kit to build a stroker, but as you see it says balancing is required and that means the kit is 600 bucks plus shipping. I found a kit on ebay with an eagle cast crank, forged I-Beam floating rods, Teflon skirted speed pro pistons, flexplate, balancer, clevite rod and main bearings. It came balanced, shipping was free and I got it for 680 bucks. To me that is the best deal out there for a motor that is going to be around 500 HP and 6500 RPM anything more and you should spring for a better crank (forged) I checked every tolerance on that crank, and the only thing was that it was about .001 too big on the rod journals...but low and behold the company sent the kit with .001 smaller rod bearings, everything went together with .0015-.0025 clearance.

That might have been an exception but here is a link one of these kits.
