|HAMMER1DOWN||I won't be putting the 302 in the JK after all. My old man found two TJs that I am picking up for 3K for the pair. Going to make both of them toys and drop the 302 in one of them|

I seem to recall Ford 302 swaps were somewhat common for CJs.
Some companies even had kits or mount for them, if I recall correctly.

|MotorCityJK||Been a long time since I wrenched on a sbc. Had a '71 Chevelle in hs/college. The Ford is nice w/ it up front. Is it assembled? Measure from front of water pump pulley to back of dizzy cap + 1". Compare to JK firewall to rad minus depth of elec fan.|

|michiganadam||Am i going to have dizzy fitment issues with my sbc? Hmm|
|07-27-2013 10:00 AM|
|HAMMER1DOWN||Yep, my old man is looking for the cam, head, and other specs. It wasn't on the package slip. But she is a beast and is gonna put a lot of smiles on my face when I finally put it in a deserving vehicle. I decided to buy two TJ's from a farmer back home in MT. One is lifted and modded with a seized four cylinder and the other doesn't run but has the 4.0 in it. Both for 3K, not a bad deal. Thinking two new toys to dump money into. The seized 4 cylinder will be getting the BOSS!|

That's a healthy sbf. Would have no problem moving the Jeep along. Again...hard to tell power band w/out rpm's for those numbers or knowing what cam/head/intake.
I wouldn't be afraid of crusing the thing at over 3k rpm either. Daily drove that 4.56 geared Mustang (winters too) and that ran about 3500rpm on the freeway w/ a T5 trans (28" tire).

The specs for the base engine were these.
302 cubic inch displacement
-310 ft. lbs. of torque
-9.0:1 compression ratio
-E303 hydraulic roller camshaft
-3.00" stroke forged neutral balance crank
-4.000" lightweight forged pistons
-Forged 5.090" I-beam connecting rods
I had them put a different cam, and heads, as well as the Holley four barrel on there. Plus shorty headers and a badass distributer and starter. The dyno specs were off a motor stand but came out to 447 HP w/ 429 TQ
|07-25-2013 06:27 PM|
Tried doing a search and there's a bunch of 'em. Without knowing specs it's hard to comment but there's no doubt that a 5.0L V8 will motivate that Jeep better than a 200hp 3.8L V6. The heads/cam/intake would dictate how you need to gear it to make the most use of the powerband.
Have a p/n for the motor?
|07-25-2013 04:40 PM|
I used to know exactly all the specs on it but it has sat in storage forever. I know it wasn't cheap and it isn't a stock crate. I ordered it to be turn key, Holley four barrel, racing cam, and a bunch of other stuff. It's a beast it dyno'd over 380 closer to 400 HP. It is more aftermarket than stock. The headers alone were close to a grand that I remember.
Like I said before I had bought it 7 years ago or so to drop in my 81' F150 and never got around to it. Now that I have the Jeep, I am slowly turning from ford trucks over to the Wrangler side.

|MotorCityJK||If it's a FRPP crate engine it's not the revver the original BOSS 302 was. I'll look up the specs. I used to daily drive a carbed 302 Fox body hatch and built a few of my own motors. I'm no expert but could offer an opinion based on the cam & heads and power band vs your current motor.|
|07-25-2013 06:52 AM|
Well a smaller engine is always going to make power higher up. Thats why we have such low gears with the v6. Whats the horsepower on your engine? Is it stock? Apparently the original made 290 but ford racing has a 340 hp crate engine. The 3.8 puts out just under 200 and the 3.6 puts out just under 300. But a v8 is going to make more low end power than a v6. You probably also will still have to regear.
Do it. Do it. Do it. Do it.
Trail capabilities? I always see stock silverados with v8s wheeling where i wheel. Theyre always smiling. But i like to climb sand dunes and throw 10 foot tall rooster tails in 2wd in sand. A v8 would do that great...

|HAMMER1DOWN||My old man and I are great friends with a drag racer back home. He did some measuring and got specs and said if we put a cowl hood on it would fit rather nicely. He would be the one helping us out for the most part, he has a couple shops in our little dirt patch of a town that he uses to work on his drag cars. He is helping free of charge mostly cus he wants to see it done. And thinks jeeps are badass, even though his wife won't let him own one!!!! But honestly how much gain am I going to get out of the BOSS outing the big 37's and driving the equivalent to a parachute down the road, better question is how is its trail capabilities going to fare? One guy earlier had mentioned that it is a high revving engine.|

|HAMMER1DOWN||I love the discussions on here, giving me lots to rhino about. As for selling my rig now and going with th newer model, that's out. I have just over 9k in the gunslinger as she sits. Just want to give her the power she deserves and needs to eventually be turning those 37 IROK's I've had my eyes on. And still be cruising highway speed without being in the 3 - 4 k RPM range. Besides I already have the crate engine and tranny that's been sitting for 7 years, need to do something with them.|
|07-24-2013 11:05 AM|
|MotorCityJK||I'd agree on the gear swap. Easier and cheaper in the long run.|
|07-24-2013 10:50 AM|
Youre probably right about the cost and the 302 too. But a bigger number is always better right?
But a stroker kit that doesnt tell you what the new displacement would be, somethings up with that. Im just going to put 4.88s in for now and i think thatll get me plenty of power. It was ok before i put 33s on. Not great but ok.
Now dont get me wrong, i love an old small block chevy or 351, i also own a suzuki katana 600 and a hyundai santa fe with the dohc 2.7 v6. I also had a chrysler sebring with the 2.4 eclipse engine, and a honda atc 200s (sohc 4 stroke). And three volvo 240s with b230fs and b21fs. And i also had a ford f250 with 351w and c5 and ford 9 inch. Ive also test driven an 07 mustang gt, and a couple of those gm turbocharged 3800s, etc. And the vortec 5.7 in a downright dangerous front wheel drive setup.
All of those are great motors. But most of those sohc/dohc cars have very small displacenents with impressive power output. My hyundai gets torque steer to an extent that it shouldnt be front wheel drive and people ask me if its a turbo lol.....
But id still take a 302 over an dohc engine. My f250 mightve been slow but atleast it sounded cool as hell
|07-24-2013 10:04 AM|
I'd argue the 302 has it's benefits over the bigger Windsor. 100# less block weight and the deck height is shorter.
Also disagree with the OHC automatically being better. We can talk Mod Motor vs LS if you'd like. Ford screwed the pooch w/ the first move to SOHC/DOHC architecture in the early 90s. They could have retooled the Windors, left them OHV, and just brought them into this century like GM did. Would have weighed less and packaged smaller.
|07-24-2013 09:57 AM|
Also i point out that 427 windsor stroker kit is half the price of the 3.8 kit. WTF?
And if he did want to mod the v6, atleast a 3.6 is a better starting platform. It's over head cam. You could probably port/polish the intake and put a custom exhaust on it WITH HEADERS for quite a bit more airflow. airflow = power, of course. overhead cam engines always have a lot of potential for air flow, but stock manifolds are never designed real well.

How about this as a different take on the same goal... You have a crate 302 and a 2011 JK which probably still holds some decent value. Selling the engine and trading the 2011 in for a 2013 would get you an immediate 85 extra horsepower.
Unless you're really dug in with mods on the existing Jeep, it sucks to tear down and rebuild such a new engine, voiding all the warranties in the process.
|07-24-2013 08:32 AM|
|MotorCityJK||I'd look into how much "stroke" you get w/ that stroker kit I posted. Only gave the link to show what's out there. I thought I remember reading you don't get much CID gain w/ that kit to justify it's cost.|
|07-24-2013 12:24 AM|
Be prepared to re-engineer the suspension. If the Ford engine weighs more than the mini-van motor, you'll need a higher spring rate. The JK is mod friendly to only Mopar.
You would be far better off to do a 1st Gen Bronco or a CJ with what you have in mind.
|07-24-2013 12:04 AM|
|HAMMER1DOWN||How difficult will it be to install that striker kit that MotorCityJK posted? That seems like a reasonable option to me, along with a few other things like exhaust, intake, chipped to boost the power and torque. I am going to 37's after my 33's are done for. I really don't want to be lugging around to bad.|
|07-23-2013 12:57 PM|
You want to STROKE the engine, with a different crankshaft, to get more displacement.
I would atleast start with an overhead cam engine like a 3.6.
|07-23-2013 09:57 AM|
|TOK||If you're married to Ford power and don't care about stuff like air conditioning, why not save yourself a world of aggravation and build up a first gen Bronco?|

|07-23-2013 08:56 AM|
|MotorCityJK||That's a stroker 4.0L. I think they use a 258cid crank.|
