Hello I was curious if anyone happens to have any knowledge on stroker engines? The reliability of them and any special care I should take with it...
.
I should add that the included message was from the guy that built my jeep.

run synthetic oil, wix filter, same spark plugs that he installed when he built the stroker and always use high test premium fuel.

change the oil at regular intervals.

but that's all obvious, i know nothing more. wish i had a stroker. thought about it, maybe someday...

Apparently you also have a addiction to jeeps lol, this is my 5th wj. I got it cheap as f***, $650 and it was mine. There's roughly 50k on the engine since the rebuild and I haven't yet put it on the road. I obviously want it to last a long time and wasn't aware it had a stroker untill I happened to find the guy that built it due to a random sticker on the rear window lol.
I bought it off someone that obviously didn't know what he had. Heck, the lift alone is worth more than I payed for the jeep and research shows me the stroker kit wasn't cheap as well... Total score here lol

Amsoil is what the guy that built it used. Not too sure about the guy in between though

Strokers typically do not like to rev as high on the rpm range as shorter stroke engines, but that can be overcome by using premium parts and performing precision balancing. Otherwise, they do not require anything special beyond a regular engine.

To put this in perspective, a chevy 327 and 350 both have the same bore. The 350 is 3.48 stroke compared to the 327's 3.25 stroke. Does the 350 require any special maintenance over the 327?

This is true. And thank you for that, I just don't want my engine to blow up on me lol. The jeep body has 249,000 on it and the engine has roughly 50k according to the guy that built it. So all in one shot, I have the most milage on the jeep of anything I've ever owned, ( and I've had alot of cars) but the engine has the least of any car I've owned lol

That's quite a paint job he did on that motor! Sort of looks like a carnival wagon, LOL! The thing I found about a straight 6 is it doesn't require complex balancing externally like a V8. This is because it has 3 inertia moments every revolution that tend to cancel out vibration. The big thing with a stroker is the piston skirts are shorter because they come out of the bore on the bottom farther. At high RPM's this would tend to make them twist a bit more than a stocker. This engine has 7 main bearings which makes the bottom end a lot stronger than the earlier 6's that only had 4. Probably why they last so long.

It is in fact a strange choice of colors lol and well, under the right circumstances, it could be like a carnival ride lol.
