how to tell if you have a stroker?

[superj]

ok guys, here is the harmonic balance bolt and its washers. it is very hard to get a flashlight and an ipod in there to take a clear picture so this is as good as i could get

[SilverXJ]

That is a good enough picture, and yes that appears to be the spacer in question.

[tequila mike]

The locator tabs under the distributor hold down.
They usually need to get cut off to reindex the dist, so it will start.
Do you have a compression gauge?
If it is a stroker it will have higher than stock compression, very easy test.

This is what mine looks like.
That weird about the 4.2 head.

[superj]

Nnot a working compression gauge

[superj]

I don't know anything about locator tabs so I can't say anything about them. The distributor turns like any other distributor when you need to adjust time

[Dezertxj88]

Are we sure its a 4.2L head? 2885 is the 4.2L casting I believe?
If its 2886 then its a 87-90 jeep 4.0 head...also known as the low output/low flow Renix head.

[superj]

Do the remix heads match the holes on a cj offenhauser intake? The port holes, not the bolt holes?


Where is the numbers I need to find on the head to be 100 percent sure on the type it is?

[tequila mike]

The 4.0 dist. is not adjustable by design.
The computer takes care of timing.
All 4.0 distrubutors have an indexing fork,ears,tabs what ever you want to call them that only allow it to clamp down in one position.
Get a compression gauge, buy, beg, borrow or steal one.
It will tell you a lot about the health of your engine.

its on my list but the vacuum gauge is the one i use more.


i have a cj distributor, pre smog, in my jeep. i have hte advance set to the 18 degree slot

[tequila mike]

i am getting it.
You have an 87 wrangler
With a 4.0 block and all the other 4.2 stuff bolted to it.
You can't know which internal parts are in it from the 4.2 with out some disassembly, or a compression test.
To save some money the po used the 4.2 head so he could use the existing manifolds, computer etc.
What does it matter what you have.
Just run it.

[superj]

that is what i am doing, for now. i am stuck though.

i have a 302/c6/np208 in the garage waiting to go in.

i am trying to decide to just keep this and buy another jeep to put the ford stuff in, for my oldest son or put the ford stuff in mine and put this into his.




the guy who built this jeep appears to have really liked hte jeep. he did the stroker work and kept everything stock otherwise, maybe because where he lived did a visual on emissions, who knows?

all i know is someone either kept it perfectly and did stuff to make it better as a daily driver.

I don't believe the photos superj posted are of the "spacer", they look like a 258 dampener to me, it looks like the pilot on the hub that's for the auxiliary drive pulleys, here's the one off of my 258, the spacer should be about 10mm thick, like the one tequila mike posted.



Is it a "V belt or a serpentine setup?

[superj]

its got one serpentine belt that is a pain in the butt to change

i won;t be able to see your pics till i get home, work blocks photobucket pics.

i think mine is thinner because 10m is almost half an inch and this one is not almost half an inch wide but what reason would a person have two of those stacked on top of each other?

[tequila mike]

The health of your engine is what would drive me to replace or not.
You cant know the health of the engine without a COMPRESSION TEST!!
I am out.
