What type of problems did the motors you know failed have? Also what type of driving, hardcore wheeling with a lot of throttle or more a DD?
I also read what you said as you meaning you can do a LS for basically the same as the stroker.
Well one of the motors had problems from the initial start up once installed in the jeep. Motor was was pulled, returned to the machine shop, same thing happened again when it came back, the jeep is on its third 3.8L stroker. Most notable was the customer service, or lack there of. Basically the shop pinned all blame on the installer, not their machining. It's a long block from 505 performance, so how does bolting a motor into mounts on frame rails cause two catastrophic engine failures at start up????
While at King Of The Hammers I met three separate other racers that noticed EVOTJ was running a 505 Performance inline 6 stroker motor. All three asked what we thought of their work. I said that we had really good luck with the TJ's stroker motor. Then each one recounted their own horror stories with the shops work and customer service, specifically the owners attitude. All three were pretty disappointed with 505 Performance and have never used their services since.
Now all I know is I have seen first hand three bad motors, all 3.8L strokers. Two from one JK which is now on its third, and the third motor is actually in the JK featured in the article. That last one I am not going to discuss due to connections to the magazine, if they want to write about it, they will. Probably will not happen though.
The racers I met at KOH with a bad taste in their mouth for 505 Performance, well those are just stories told to me, so I considered it almost hearsay with the exception that it is supposedly to their own motors and not someone else's. So take that for what it's worth.
Even without any bad events ever happening to the 3.8L to 4.1L stroker kits, I would not have wasted $5400 on a long block that gives you such meager improvement over stock.
