#1) I own a Jeep
#2) This is my first post (please pm me if I jacked up; ie posted in the wrong spot, not applicable, clean up my post, etc)
Specs of the current Jeep:
-1983 CJ7 bought in O-city for $4500 very used (best i could find)
-32/30 Webber carb - 258ci AMC - Borg T5 (5speed man) - dana 300 (4:1 ratio i believe)
-As far as i know, stock axles and drive train - from what i have found its the Dana 30 front and AMC 20 two piece rear axles.
-15in steel rims with 33" BFG M/T tires @ ~90% tread
Condition of the Jeep:
-Very used. engines is pouring oil when going up hills. rust holes covered with welded diamond plate. front drive line is very loose, tranny grinds a bit in 3rd gear, and i have doubts about the diff's.
My level of mechanical ability:
Honestly, NO experience. But I'll be damned if I cant be a shade tree mechanic when I can breeze through OSU with 2 majors in 4years.
What I have found out:
Mechanics is complicated. I want to do a 4bt engine swap and mate it to a manual tranny while keeping my dana 300. the 4bt weighs in about 700lbs wet. the jeeps used to have the AMC 304 that weighed in about 600lbs wet. so not a whole lotta difference. Im not hard core wheeling at this point and just want it to drive on highway at this point.
First question: Can i convert the T19 2wd Tranny into a 4wd tranny? and what needs to happen to do it?
Ive been looking at pictures all day. Im pretty sure the T19 is shorter than the T5 i currently have. I know the output shaft is longer on the 2wd version vs the 4wd version, and i know ima need a 23spline output to mate with my dana 300. and i know ima have to take the tail housing off the 2wd tranny. I know they make an adapter to make it happen, but its a couple hundred bucks.
here is the link to the adapter:
So can i just remove the tail housing, swap the main shaft with one that has a 23 spline output, and mate it up to my dana 300 with the adapter and no worries?
2nd: What bolt pattern for the bell housing do i need to mate the 4bt to the Ford T19?
My understanding is as follows: there is an adapter plate that bolts to the back of the 4bt allowing for a bell housing of a certain bolt pattern to be attached. flywheel attaches to the crankshaft. clutch plate, pressure plate covered by the bell housing and a starter that mates to the bell housing to get at the gears on the fly wheel. fork and all that goodness is based on the bell housing. then the tranny.
So is there another way where i can forget all about this adapter plate?
3rd: Will the input shaft on a Ford T19 mate with the 4bt?
I think the 4bt input shaft is 10 spline. When i was looking at an NV4500 (not doing that swap due to cost) it said something about 1.25 vs 1.125 diameter input shafts, meaning that some engines have a different input diameter on their crank shafts.
Can anyone tell me what the input diameter on the 4bt is?
And finally, I wish to keep this build cheap. My major problem is i KNOW im missing a bunch of little pieces and i cant let this thing nickle and dime me to death. I have figured out the mounts, and the hydroboost solution for brakes. Im going to attach the tranny to the engine and put it in as a single unit, mate it to the T-case and install the motor mounts where it sits.
Can anyone advise if this is a go or nogo and where i can improve this plan? I am intimately familiar with the official 4bt swap thread here:
