Help me stroke my 4.0

[Tortoise]

The engine in my 93 XJ gave up the ghost. I want to do a 4.7 stroker kit but I have no idea where to begin...
I need help planing it out and getting it done right.
I am in Spanish Fork

This link has a bunch of great info on parts, also you can look up more threads by YJ_and_Corey. There was an issue on Pirate a while back that caused most of his pictures to disappear and his threads to become locked, and for him to become MIA, but still in my opinion he knows how to build a stoker 4.0 as well as anyone.

There was/is also a company based out of Utah that was nationally known for building stroker jeep I6's, but for the life of me I can't remember their name.

Is it Golen?

THanks for the link. Golen is out east and it is pretty tempting to just buy a long block

Is it Golen?

No that doesn't sound right. I wanna say it was someone up in Logan/Ogden

Out of Utah yes, stroker kits yes, still not the company I am thinking of though. The one I am thinking of only does jeep I6's

And that is just what I was looking for

Now I need to decide if my exhaust and cooling system could handle being stroked...

When I did mine, I used this site http://www.jeepstrokers.com/forum/. Found all the information there. I tore the engine down, took it to the machine shop, and then built it back again. I went with a 4.5, wanted to stay on the safe side.

so with mine being .030 over already and having the comp cam its got would i be a 4.6 or 4.7 in mine if i swapped in the 4.2 crank

This a great resource for building a stroker!

clegg engine and machine shop in orem does 3 different stages of stroke kits for the inline 6, the engine shop, not anything to do with the auto repair shop, just fyi

Any updates? I'm thinking of stroking my 4L

 

[amp713]

following since that's my plan if the 4.0 ever gets wore out.

I am in the process of stroking mine.

Of course since it is me I point to the kit and pull out the Visa.

I have been working with Kevin at Clegg Machine in Orem. He seems vary knowledgeable. Basically they have built a ton of these and know what works well. People ask me what my cam specs are, I reply "I have now idea Kevin at Clegg told me it would work great"

I dyno-ed my jeep before and will do it after to see the actual gain. (of course a OEM motor with 200,000k to a fresh stroker is not a fair comparison but it is a comparison)

I am doing the high compression kit.
