Mine fits in the category of a mild DD stroker and it has a ported head with stock-sized valves and a stock cam.

First I'm sorry for posting this if it's been covered. But I haven't been able to find it yet. What are your thoughts on a big valve head vs a high lift cam for a mild stroker DD build. I don't see the point in doing both. And the horror stories about cam failures have me a bit leary about the cam route. Let me know what you think.

Justa FYI, My daughter raced the jeep at cleves ohio over the weekend. I built her a leftovers parts motor for her to learn on. Low port head, stock piston, stock 258 rod, good 248/260 at .050 cam, Bolra header, but left the tripple TB manifold on this little stroker. I did a lot of things to lower the performance but it still ran a 5.48 in 300 ft! Transbraked 4300 on my N2O converter and shifted it at 5200. BTW, she did an incredible job driving it from the first pass out! I may be in trouble!

yes they are assembled and are ready to run.

ill have to dig the flow info up, memory right now is saying the final number was in the 283 cfm range on the intake
my original post mentions what type of spring and retainer is used.
valves are stock jeep pieces

That is the best way, the only other MAYBE????, that I know of that's not 100% by ANY! means is there might be a spacer on the front of the crank for the dampener, but there are short snout cranks that don't require them or the crank snout can be cut to length on a lathe, I trimmed my crank snout so it'll look stock!

easiest way would be to drop the oil pan and get the numbers off the crank to see what crank you have. all it'll cost you is an oil pan gasket, oil and about 30 minutes of your time. the faq section on the site here has all the block, crank, and head numbers so you can find out what everything is

As u know ,there are hundreds of combos on this site, but not necessarily one that would work for your exact application. The 24's might seem initually rich, but at w.o.t. ( where the pedal is 95% of the time in a full race application) they would definetly be a step in the right direction.( lean is bad!) There are plenty of ways to tune, but reading your plugs can be as accurate as any, and inexpensive. Speaking of inexpensive, any trans/torque manufacturer/rebuilder, can build a stock converter to max stall without spending more than 300.00

i have some questions for you fellas and i hope you can help me figure out what my jeeps got under the hood.

side note: i write a lot

----history-----
traded lifted cherokee straight across for this jeep to college kid from houston. he wasn't a mechanic and this is an old wrangler, carb'd. he wanted fuel injection and the lifted look while i wanted a wrangler with 6 cylinder, auto, hardtop and full doors. it was a swap made in heaven . the wrangler had some little issues which i recognized as soon as i popped hte hood on it when we met to swap. the cherokee was perfect but i was ok with it because it was the carb and linkage system that was causing this guy's troubles. we swapped and i drove it home from victoria, roughly 2 hours with no trouble. the kid tells me afterwards "the jeep has had some work done on it. the previous owner swapped the block and did some work but i don't remember what it was." hmmm, i wonder what.

the carb was a crappy weber 34 two barrel. it ran ok but dieseled like crazy when you turned it off. no matter what i did, i couldn't get it to stop. and the jeep got terrible gas mileage, 10-11mpg. the dieseling really bothered me so onto craigslist i go and find a stock chrysler two barrel holley from a 68 something with a 340 or 360 v8 for 20 bucks, SCORE!!! i rebuild it and drop it on and what an improvement. the jeep is badass. can smoke a tire once in a while and runs down the highway up to 100mph like nothing. i am living the good life.

but, life moves on and the good life becomes normal and things i didn;t notice in my joy to have a non-dieseling jeep start to pop up. gas mileage has not improved one bit and hte jeep idles terribly rich. i learn about vacuum gauges at this point and tune up the carb. runs great but i realize i can do better so i start with the gauge and screwdriver and a mixture screw snaps off jaggedly.

dammit, what the heck?!

i pull the holley and throw on a motorcraft 2100 and it is back to running. not as good as with the holley but ok. dang it, for some reason, i have lost a huge amount of power and have to floor it to keep highway speeds. gas mileage has increased though. i cannot stand the lack of power so the motorcraft comes off and the intake comes off for an offenhauser intake i got off ebay cheap. motorcraft goes back on and nothing has changed. dammit!!

i start researching jeep mods and learn that the reason nothing fits when i buy 87 parts is i have a 99 block in my wrangler. why the hell would someone put a 4.0 block in a jeep under a 4.2 head? is something done to this jeep i don;t know of?

after the intake swap and reading a lot, and discussion with fellow jeepers on other forums, we have come to the possible conclusion my jeep has been stroked.

how you ask? well, let me list the ways.
4.0 block
4.2 head
old school distributor with 13/18 advance plate
jeep smokes the tires when i have 225/75/16 tires on it, larger then stock!!
previous previous owner mentioning to previous owner engine work and block swap
jeep smokes tires with oversized tires on it
jeep is a light to light dragster (for a jeep)
jeep smokes tires

i am running the offenhauser intake and a holley 4 barrel currently. i just put 31" tires on a few days ago. it cruises on the highway like nothing and can pass people with ease. i know the 4.2 isn't known for doing that kind of stuff.

what can i look at, without tearing the engine down, to see if i have a stroker or not. everyone tells me i do and i will happily believe them but i have this back of my mind voice saying "you cannot verify that so stop saying it is."

give me some ideas fellas.

here is the monster, on the previous rims and tires

Will adding a fuel regulator and a larger fuel pump help me with this issue ??

No. Your stock fuel pump is already man enough for the job, and the stock 49psi regulator is integrated with the fuel pump & gauge sending unit so it can't be changed. With 24lb Accel injectors and a 49psi regulator, the injectors will flow 25.5lb/hr so your engine shouldn't be running lean.
The base ignition timing should be 10*BTDC with maximum advance at 34*BTDC. Sounds like your timing and fuel curves are off. How does the engine perform with the stock PCM tune?

I'm Planning to buy a Fuel pressure gauge to check the if the pump is working properly. It is 15 years old pump and that is why I sometimes suspect that it might be defective.

Apart from the knock, My PCM runs much better with stock tuning. The engine feels more powerful and does not get chocked at low rpm.

It runs alot better now but we'll see, Racing 89 do you think it's possible were getting too much bite and pulling the motor out of it's power range? Were running 33 boggers, welded rear and here's a pic of her coming through the lights and it looks like it's hooking real good and all the other jeeps were flat like they were driving and not pulling...Make sense?

I'm tried running 98 Ron ( 94 AKI) fuel. It helps, but the knock is still there. I can't seems to find octane booster but I would like to try that as well.

Running such a high octane is a pain because most (if not all) of the gas stations near offroad spots do not sell them ..

In topic:  2.5l too 2.9 505 stroker,  Jim K in PA wrote:

"total failure" is a bit harsh. 2.5 engines are just as solid and reliable as the 4.0, just 1/3 smaller. In a light Jeep, they do just fine and have done so for decades. However, I agree with the previous poster that stroking a 2.5 is not necessarily a wise investment. In addition, as you get up toward the 3.0 liter mark in a 4 cylinder, harmonics tend to get bad quickly. It will not be a smooth runner without balance shafts (if you care about such things).

But, different strokers for different folks-ers . . . er something . . .

most people do not realize that porting cast iron heads is becoming harder and harder to do. most shops such as myself and gtp do not even want that kinda work any more. very time consuming and the removed material is not good for the porters health. lol

again. this is not as you can see some back yard port work. its a professional job done by people who know airflow. we have and still hold records and stand by our products.

this is a cyl head that was ported by F.R.I. , An affiliate of G.T.P. racing here in houston texas.

the head started out as a factory casting 0331 head, that was checked and found to be suitable. the head was ported and poliched. chamber work was performed and each chamber received a proprietary 5 angle valve job that was then hand blended. the valves are backcut also. the head was cut .030 for a slight bump in compression and the spring seat modified to allow the use of a modern spring pack.

i have installed a decent valve spring from a 5.7 hemi along with the factory lightweight retainers. the spring sits at 92-95 pounds on the seat right now and has a open pressure of about 320-325

should be perfect for you mild cam guys out there.

i have pictures of the work and i guarantee my work. i am known in the ls1 and the hemi world this head was for my own jeep. it has all the "bells" and whistles i would want and have on my own parts. i have no time to install it and i am tired of it just sitting here without out being used.

if you are serious about power and running good? this is the head for you. i recomend a cam swap amongst other upgrades to take advantage of it.




i am going to ask 1000.00 for the head but i am open to serious offers. lets talk...

please email me or text me. i am not on the internet enough to keep up with replies here or personal messaging.
