Mass produced reman engines with a few year warranty are always attractive. I though prefer to have a good reputation machine shop build. It's nice to know and actually talk to the ppl doing the work. Plus they are again not u singing the lowest cost parts they can get ahold of. Not saying all are that way but to many a penny saved us a penny earned. But that being said spending a few extra bucks on good bolts and better pistons goes a long way in the way a motor last too. You can run the correct way, do all the proper maintenence but if built with substandard cheap parts from over seas benders problem will most likely be close behind.

If rebuilding, good arp bolts, not bottom dollar piston, quality oil pumps and bearingand rings and even switching to roller cam lifters adds some money to build, but if only doing once as compared to twice starta to figure in the extra 750 or so bucks is alot cheaper than another build a few years later.

Good quality machine work is just as important too. There is a big differance in a motor balanced to 2 to 3 grams as compared to 20 to 25 like some of these mass producers do
