The ReCon brand is the same that Summitt Racing sells.. I sold several when I was working there part time and never had any complaints with the engines at all. They came with a 1 year warr and I believer you could get a total of 3 years for $100 extra.. I know of several personally that are still going after 3+ years and they did the quick swap on the weekend...now they did replace all other parts at the same time, ie water pump, starter, all hoses, belts etc...and they are still going. If I did not have the ability to put my own together I would go this way...and I have put two in for friends myself...very good quality..and they offer several different options of upgrade abilty, where they replace all valves etc, v/s just machining the existing valves...and they also offer performance engines with the same warr...but they are a little expensive, but have Edelbrock heads etc....
