Jeep Strokers

I'm new to the stroker world, but I love this community already. You are all extremely dedicated to your machines. I have my donor 4.2 block, and my HO head from a 92 cherokee already. I'm just looking to build a bad ass stroker motor. I don't care if I have to run premium in it. I just want power.

I'm looking for a shopping list of parts . So if any body wants to help me out I'd really appreciate it.

4.0 block not 4.2

I have both. I was under the impression the 4.2 was the better block to build from?

No. In fact because of the lower deck height I prefer to use 4.0 blocks 91 and up.

Some of the info is outdated as it applies to particular part numbers but the basics are there. Don`t get caught up to far in "recipes". Just use them as informative baselines.

There are a number of pretty old but smart guys on here. Do a little research on your own to grasp the basics. Us old guys will help out with particular questions.

K ?

Thanks for the help. I will check out the Dino site tonight. I've got the 4.2 engine apart already. I might just build two of them for the fun of it. I feel like building this motor is a good idea, but wringing every little ounce of power might be harder than expected.

Dino's site is useful but again don't get hung up on particular specs

Well, after much extensive research.......and on this site I feel like I'm back in college ....... I have decided to go with a basic build to start. I will use stock valve train items and build a basic 4.2/4.0 head stroker. This leaves the 4.0 HO block free for the winter to rebuild and bag for a future project. I will do a small amount of port/polish work to the head, and probably buy the new injectors. I feel that the main issues to address right now are getting a nice balanced flow from intake to exhaust with proper fuel management. Since I will be opening up the head I will probably scavenge a throttle body and have the lip milled. I have access to a small machine shop and a moderately experienced machinist almost daily. My wrangler has a few issues that need to be addressed in the mean time......suspension and re-doing the transmission lowering kit. Nothing to extensive, but it all eats away at the few precious months of summer up here in Maine. I definitely thank everyone on this site for all the info. You guys are amazing.

a 4.2/4.0 head is not a stroker.

It is a 4.2 with a 4.0 head. That being said you will be very happy with the performance increase the 4.0 head will provide. Use the 4.0 intake/exhaust manifolds or a 4.0 header. Strongly consider upgrading to the 91-95 fuel injection over your present carb.

Recently helped a friend do this exact swap. Used the 91-95 cam and freshened up the head with new but stocks springs and such.

I still plan on doing the stroker.....just not until the 4.2 is done. I will definitely switch to the fuel injection. One of my friends that put a 4bt in his cj is helping with all the stroker specs for a later build.

The 4.2 build is pretty straight forward I think. Which push rods did you use?

Even the factory used a number of different pushrods over the years. Only way to be sure is to use a PR length checker. That way you can dial in exactly what you need based on your combination of parts.

Summit 15 bucks or so.
