I just rebuilt my engine and used a kit from RPMmachine.com
I think my total cost on the kit I used was about $390. But since I was doing a complete rebuild the price seemed to work out. For that amount of money I got a complete gasket kit, new oil pump, new pistons (30 overs), new bearings (10 under), new camshaft, new timing gears and belt, hydraulic adjusters for the head, new freeze plugs, and some other things I can't think of right now. All of the components were of a fairly good quality, stuff like a Melling oil pump, Sealed Power rings, Durabond bearing, & Silvolite Pistons. You could of bought better, but nothing was cheap. The only stuff not in the box for the rebuild was a new water pump, thermostat, pre-lube, and spark plugs.
I did have a problem with delivery, but that was a problem with UPS not RPM.
I may be wrong, but I thought I got a good deal.
