I think you might be better off asking this question over at Pirate

Hardline crawlers would be another good resource

Just do it.

I haven't done a swap in a Jeep but Have built a 350 for a swap.
In my case I put it in an 87 Pontiac Fiero. Other than a VW motor I had never built and engine.
I found an 80's 350 with a broken crank for $100. i went to a machinist I had recommended to me. i told him I was on a budget and wanted a simple motor that ran well on regular gas. He machined the block and did the heads and help me pick the parts I needed. He said that for cheap power I should stroke it and make a 383. Crank was only a few dollars more. He set compression ratio at 9 1/2:1 and recommended a mild cam. I used an Edelbrock 600 cfm carb and a Chinese made HEI distributor. I followed the soft cover manual about about how to build a 350. When done he put it on the dyno to break it in. It made 320 hp and 410 torque. I bought no expensive parts. I had the car for 7 years and never a problem. I did eventually change to a stand alone TB EFI from FAST. Mount it up, plugin the controller and answer the questions it ask such as how many cylinders, cubic inches, idle RPM and a few others and start it and drive it. It adjusts itself as you drive.
Go for it.

350 in a TJ

I have done a few of these going back to my CJ days, and absolutely loved the end result! On a CJ it was a one day event if you took your time! I’d say look for a 400 SBC if you’re going this route. The external dimensions are the same and you start with a beefier block as many were used in trucks. If the engine is in decent shape you can reuse the crank at least, maybe shot-peen the rods if in good shape. I would also recommend a new bolt on EFI, they are so simple you can set up with a laptop in minutes. With a relatively mild cam 350hp is no big deal! I’ve had my float bowls go dry on some steep stuff before, leaving a balled up 373 SBC-CJ-7 at the bottom of the mountains out in the Chocolate Mountains, never want it to happen again! Good luck, wish I didn’t have the emissions God’s looking over my shoulder or I would do the same in an instant! Jeep did build 304 ci V8 CJ Jeeps for a few years, too bad it was a 304!

Very helpful and informative. Thanks for the tip about the standalone TB fuel injection. Do they still sell that? Do you have a link? It sounds like you got done what I want to do, just in a different vehicle.

Thanks for the encouragement!

And there are stand alone controllers for the LS platform and per dollar the LS is going to make more power.

To me it's simply silly to build based on an old small block and a carb..maybe if it was a strip car only but to DD or drive on an angle there is nothing about a carb and old small block that is cheaper or better than an LS.

Heck even if I were building a CJ I wouldn't use a carbed small block since in that platform it'd be boring it doesn't have the performance nor the allure no one is taking a picture of your old SBC with a holly, its not unique nor special.

This whole idea is short bus kind of special

• I do not want the LS motor in my Jeep.
• I do not want that level of complexity in my Jeep.
• I do not want the emissions controls that are a part of the LS engine.
• I do not want the LS EFI system in my Jeep.
• I do not want any aluminum blocks.
• I do not want or need 4 bolt mains.
• I do not want or need anything above 300 HP.

This is your opinion. Please remember that it is not *my* opinion, but HEY, it is my Jeep.

Are you seriously talking about "engine allure" in a jeep? BAHAHAHA!!! Okay Chris, how about you come stand next to my TJ every day for a week and help increase the perceived "performance" and "allure" that my "boring" little 350 might hamper?

Please.

I'll give you three bucks an hour and a PB&J and a juice box at 12:00 every day. (You only get a thirty minute break, though.)

Chris, I am sure that you are unique and special, but seriously: WTF does that have to do with anything?

Why is it that when some people have nothing at all germane to add to a conversation and what they *do* say is rejected as bing off the subject they like to call people names or use pejoratives? And "short bus special" is offensive as hell; my seven year old daughter rides the short bus, sir. Perhaps if you had not been such a hat rack about that I would have simply blown your idiocy off. But you insulted my little girl and all those other great kids. Shame on you. What are you, like 13 years old? Seriously, shame on you. You should feel shame for saying such a craptacular thing about children. Obviously your parents failed to raise you to be a decent human being.

Does that foot in your mouth taste good?

Thanks for supporting your "opinion" with information that is absolutely irrelevant to my request for information. You seem to be particularly adept at trying to force your opinions on others. Great job. Thanks.

How about you pull that foot out of your mouth and take a hike?
Or I could put my foot in your mouth, which would be preferable for everyone..

You're going to do what you're going to do and it'll be boring, have little HP, and will off no real world performance.

You're the one that started the thread talking about how much you liked carbs and "old skool" then you ask about EFI when someone brings it up at that point the LS becomes cheaper...That's called I have no idea what I'm looking for other than my i6 is dumb.

You don't want an aluminum block..great most LS's aren't aluminum so pick a random crashed truck and go to town.

If you put another boring LS in your Jeep you'll follow a path many have trodden, there are kits and tech support for them, you put some random carbed SBC you're on your own since it's silly, but please knock yourself out.

So short bus..find a SBC throw a Holley and tell us all about how great it is, so we can snicker.

Nice. This is the only social interaction you ever get, isn't it? My little girl forgives you, but she thinks you're a bit of a turd.

_______________________________

Now back to our regularly scheduled program...

I am still trying to learn about options for a 350, perhaps even block and head casting numbers recommended for such a "weak" engine as a 300 HP 350 in a vehicle as small as a TJ.

I don't know anything about TBI except that it exists. What brands of these guys are proven to be trouble-free? And how much do they cost?

Does the term "stand alone" mean that it works with its own, separate computer or do they still require the Jeep (or Chevy) PCM?

I'll save everyone all the back story about my endeavors to put a SBC into a 73 Chevy Vega back in 74 but what I did learn was that actions will get you what you seek.
Yapping on the net will get you zero progress, educating yourself with the knowledge of others that have "hands on experience" is where I would start.
Form a plan and then just do it.
Anything is possible if you have enough money to throw at it.

Don't bother responding because I won't be coming back to this thread.

I will respond, even though you may never read it.

I agree with the "hands-on" experience as a source for information, which I mentioned several times above: I'm seeking out people who have actually done this and not people who read K&M box panels at AutoZone and then think they are a mechanic, heh, heh…

I am trying to form a plan, and if you *do* end up coming back here and reading this I would very much like to learn from your experience with that Vega, if you want to help me out (or educate me) using the PM system. What you wrote sounds like it did not work out that well for you, and failures are more educational than wins, so I would like to hear your story.

Thanks for your information.

Fwiw... I enjoyed the HELL out of my 83 S-10 after pulling the 2.8 v6 out and slapping in a shortbus sbc w a holly and a very mild build .030 over, flat top's, edelbrock performer cam and intake and cast iron big chamber heads....

Was WAY too fast for the aerodynamics of a pickup and a HELL of a lot of fun outrunning vettes and stangs before ls's even existed....
