did the CJ5 come with a 4 or V6? The reason why I ask is that GM only has two styles of belhousing. And the 65 came with a Buick V 6, If you can machine, you'll prolly need to mill up an adapter, otherwise there's a couple places sell them Advance or Novak comes to mind off the top.

Get the wiring harness and 'puter for the 4.3L drivetrain. I take it you're going to use the stock Blazer transmission? Verify what side drop the transfer case is so you will know if it will work with the passenger side front diff in the CJ.
the cj has a 4 cylinder the f head with a t90/dana18. oh yea we plan on using wiring from the blazer. how strong is the np207 in the blazer i heard they are prone to failure. he is going to use and abuse the jeep. one more question i have a set of dana44's out of a 75 scout are they to wide for the jeep.

The front may be too wide to properly center under a narrowtrack frame without outboarding the spring perches. Maybe somebody here who knows CJ's better will know.

as for the 700r4 its to long of a unit for a cj I used a sm465 trans along with a dana 18 transfercase
the 4.3 will need to be seated aprox 4 1/2 inches to the left with front of eng tilted up about 4 inches in front and 1 inch in rear to clear all your steering and starter and driveline yes its alot of very teidious measurements to make it sit right took me 5 days to get the proper alighnment I wanted before welding in mounts , just have patience till its right dont rush it

If you keep the T90 it may be your weak link if you abuse it too hard. From experience I know they won't hold up behind a V8.

anyway you look at it ,you want a rear drive shaft legnth of at least 22 inches any shorter ther will be drive line problems, turbo 350 would work with right tail shaft but most will be atleast 3 iinches longer than needed causing a bad alignment between transfercase and rear yoke most will come out closer to 16 inches wich is to short in my standards and also many others will agree causing a bad un balanced drive shaft causing wobble and major wear of parts in driveline alot faster than normal

I used to own a 87 s10 blazer 2wd it had a 700r4 auto;transmission it seemed too weak especially on hills. I would go with the 350 turbo trans if it will work....good luck..keep us posted...ps we love pics send us some!
yea i would love him to stay with the little f head. but he has other plans for the little cj-5. first he put 31/10.5 on it. them it started to over heat found out his distributor was bad(found the springs rolling around) fixed that. the gear on the bottom of the distributor was twisted on broken and it took out the gear on the camshaft. now he is fed up with the f-head. he is trying to do this on a budget. i even told him i would sell him my ihc 4 cylinder 196 if we could get it to fit. i have 75 Scout i use for parts.
