Engine swap cj7

I'm new to the forum and have read a lot about engine swaps and am looking into doing one way down the road and was wondering what the best one would be I have a few in mind and was looking for the pros and cons of each over all I want power a lot of power I wanna be able to hit the peddle and watch the tires smoke away as I tair down the road

So first is the 4bt cummins swap... I have a 6bt truck now lots of torque but lacking in raw horses

Second the 350 swap... I know you can push out an a$$ load of power from them but fuel injected or carbonated? I have had the issue of the carb dying on steep hills and it kind of sucks

Third the vortex swap haven't herd a lot about it would live to know more...

Forth the ford 5.0... I know that may be the most expensive however they are arguably better than the chevy

Fifth the 4.0 high output i6

I have now a t176 with a Dana 300 what would make me bullet proof for tranny and transfer case? I wanna keep a standard shift in it

It may be cheaper and easier just to set fire to the tyres.

Hopefully your not roastin new offroad rubbers! But I'd go with the 350 swap. I just did it and am very happy with it. And if you do any wheeling the fuel injection is night and day. Find a tbi 350 for nothing and throw it in

Just upgraded to dana 44 front and rears. Stock dana300. Could have adapted to my T18 but I wanted the AX15 to have the overdrive with my new 4.88 gears in the axles.

That T176 is a pretty rugged trany and you can adapt it fairly cheap. However you need the chevy bellhousing, flywheel, clutch and depending which year you find that stuff the slave cylinder and a master cylinder from a cj with a 4 cylinder. $12 from Napa. Novak also has the correct pilot bearing. Just tell them what trany your using.

No, I built my own fuel injection with an 88 1500 system for my 82 350. Manual temp and oil pressure gauges. The speedo is fine because its gong to the dana 300 still, and the tack is also aftermarket.

No offense but if you're calling an engine "carbonated," I would stay away from carbureted engine choices. Also, I know this is an internet forum but for all of our sakes please use complete sentences and proper spelling; I can barely understand that first paragraph.

The primary factors you need to figure out first are: budget, time commitment, and skill level required. A lot of people will tell you about the terrific deal on an engine they got at the junkyard but then come to figure out they have to spend twice as much finding parts for that engine. You could also have the ideal engine setup in mind and then the project fails because you didn't have enough time to actually complete it. Visit the Novak Adapt website; they have a lot of useful information about engine swaps.

I apologize about the bad spelling I will now proof read the auto correct on my iPhone can be a pain. I have plenty of time and skill is not an issue. I would like to know what engine would be the best platform for a great power house. I apologize I am not an English teacher I will use punctuation.

For out of the box power an LS2 would be a great option. I dont know how long a T176 would last doing burnouts all day though.

check out BBC's build. he's just starting to hook up an LS2 I believe.

I've got a 5.3L LM7 and it will roast my tires just fine on occasion but I rarely get after the skinny pedal

1985 CJ7 Project
Phase One : 5.3L Vortec/4L60E, Moser axles for AMC20, Twin Stick'd Dana300 - Completed
Phase Two: Bedliner, Rollcage, Seats, BESRK Rear Bumper w/ tire swing, Soft Top, and a few other goodies - Mostly Complete
Phase Three: Waggy 44 front, Scout D44 Rear, 4.56's, ARB's (F/R) SOA with YJ Springs, 35x12.50x15 BFG MT - Not Even Close to beginning

Also a mostly rust-free 1970 Scout 800A That I'll get to start working on someday...

If you have the duckets... a 5.3 or 6.0 would be the best bet! But building up and older 350 isnt a bad idea either if cash is more limited.
