ok first question and another

Isn't that back to front, ie front of the Jeep? Lever all the way back is 4 low?

Short list of good junkyard carbs for Jeeps: Motorcraft 2100 or 2150, any Quadrajet.

New, Holley makes a Truck Avenger 4V that works well. The Edelbrock can work well. Conventional Holleys (2300 or 4160 types) are really tough to make work well IME.

Fuel injection is the best solution. 350 Chevy is easy - all GM parts, no tuning needed.

What kind of use do you expect? For anything but sand dunes or mud bogging, you don't want a hot rod. You want an engine with lots of torque, reliable, smooth pulling, and good gears. I'd put iron manifolds and a single, quiet muffler on it if it were mine. All that racket is exciting at first, but becomes tiresome and very annoying on the trail.

 

The 300 is 4L with the shifter all the way to the front, then N,2H,4H.

I didn't see a pic of the actual t-case, but from looking at the shifter it could just about be a 300 or a 205 either one, or several others. Both of those will be 4L with the shifter all the way forward, so if you have 4L at the rear then you've got something else. Try to get a pic of the tcase if you can.

 

this is what i figured out..4w all the way back shift up 2w shift up again nuetral then shift one more 4w...now i gotta figure which is it 4h ow 4l...

the carb on it now is brand new..just finiky...

i will be yanking off my flows soon off my race car..single exhaust on a sbc hurts tq..duals will help..hell the jeep even has a catalatic converter on it.

i understand the hotrod part,but i have a custom cam builder that can design cams smooth as a kitten,and when you need the power it's there.


so does the jeep appear to have a 2.5 lift?

annoying thing about the jeep is when i hit a bump something slaps hard in the back

 

i wish one of you guy's was close by...test drive it and pick on it...

 

what area are you in anyways? prob nowhere near san diego?

some other responses...

MCSCOTT is right, at least my t-case:from front to rear of vehicle- 4L-N-2H-4H, of course, this is my d300. not sure what year it is, i was stoked to find it in my jeep when i picked it up. and just to confirm... if i push the tcase shifter towards the front bumper, that is 4L, all the way toward the rear bumper, that is 4H. i', not sure why some think it is reverse from that... are the d300's made differently (reversed) from different years? i thought both dana300's and atlas t-cases were the same shift patterns. never heard of the opposite shift pattern, besides the newer chain driven models in the wranglers.

again, in regards to that carb... i really am a huge fan or that offroad edelbrock model. for a little over $300, it is the best offroad carb i've seen. . . then again, if you have the opportunity to throw in EFI...DO IT! totally the way to go if you plan on some good wheelin'.

of course, that power plant your talking about dropping in it, that is a lot of power, which is great. but when you start pushing that skinny pedal to the floor, you will probably start pushing the limits on those axles, driveshafts (especially if they are a little weak in the u-joints), or even the tranny (my case-i dumped the clutch and blew my 1st gear and my cluster gear in the tranny).

 

if it is a chevy engine and trans it is a good chance it is a np205.i'm saying this assuming a 205 will fit between the frame rails of a cj. if you can take a picture i can verify it.the pattern on the 205 is ,starting at the dash,4L,N,2H,4H. this is all from memory but we'll work it out.bob

 

The D20, used through 1979, is reversed. I've never driven a D300 equipped Jeep, but I have lots of time in the earlier models.

 

thanks alot fella's you are a bunch of help...this guy who had it before did alot work on it..the skid plates are in the way not to mention the ice and snow right now..the motor is a runner still trying to figure what year and model it came out of..i'm assuming it has a rancharo series 2.5 lift on it?..i hate the carb,cause it want's to stick so i swapped springs and pulled a little idle out and it seems run alot better just cold starts suck a little..

i promise the first warm day i get i'll post better pics and have more info on set-up

 

I don't know why I didn't do this to start with, but I will post some pics so you can see which one is which and maybe it'll help you tell us what you have. I'm mainly posting these two, because the 300 would most likely be the tcase you have if it's the stock one, but with the whole carpet shifter problem you were having I would imagine it's been swapped. I'm also gonna post pics of the 205 simply because it's one of the most common swaps if you have a sbc, if the transmission was also swapped when they swapped the engine. The shifter kinda looks like what was on both of them, and the shift pattern is the same as well.

The Dana300....



The NP205




Probably the easiest way to id it is to look at the way the shifter is connected to the tcase. Like I say though, it could be any number of tcases.

 

i'll look

 

a D20, that makes sense... i actually never dabbled with one. i had no idea they were reversed...we're both referring to the dark side of the moon here (not knowing the details of the other).

:?

 

it's a dana 300....thanks alot!..so are they good?

 

i think something is slid back,cause of the shifter/carpet thing...

i got bald tires and 4h tore up this ice/snow..
i got 5 brand new 31.5's bfg's so i'm in good shape.

 

Yup, if it's the 300 then that means it's the stock tcase. Around here they are like gold just about, and usually sell for around $250 quicker than you can tell them what you have for sale. I picked up 3 a while back for $100 each, because I took $300 with me planning on spending at least that much for just 1. You can put the Lowmax gear kit in it, and the big front and rear output shaft kit in it, and have the exact same thing as an Atlas except for the housing. Shift pattern is as we've mentioned from all the way forward to all the way back, 4L,N,2H,4H.

 

that is so cool!

so they are pretty durable?

curious what is a kick bar and do i need it?

or is a reverse shackle kit better off

 

i love my dana 300. i am much harder on my rig than necessary, v8, heavy gas foot, ugly trails... so far this is a component that i have yet to break. a killer upgrade as scott said is the stronger tailhousing with a thicker shaft. also the way to go if you do some heavy wheeling is the 4.0:1 low range kit.

you should be stoked that the d300 is in there. many people aspire to put those in.

 

yeah i am did some searching then tonight i put it in 4L for the first time...damn it crawled up 3 inches of ice up a steep hill without giving it gas!..my 79 did that but i have baldish tires on the jeep compared to 35/12.5/15's parnelli jones (btw i'm getting rid of them) on the bronco...
i might just do exhaust for now and see how this carb holds up..if it gives me problems i'll get the avenger

btw have i said you guy's are awsome on the help part?...pics do wonders lol
