cj7 to chevy

I am putting a complete chevy drivetrain under my 79 cj7 has anyone ever done this please post pictures if so. I am using a 85 chevy 350,sm465 with 208 t-case and chevy 3/4 ton axles. I mainly need the drive line angle for the rear and what i can make work for a tranny mount/crossmember

That's a long drivetrain for a CJ. Personally I'd adapt a Dana 300 to the SM465 and lose the long NP208.

I am no 208 expert but I wouldnt want the slip yoke on it. With the drive line angles you will have it will more than likely bind and get sticky. Even on my dads K5 blazer it would stick and shudder when compressing the rear axle.

You can convert your 208 to a fixed yoke (unless it is already) but I would put the money towards the 300.

The 300 would be well worth the investment.

I have a shortened silverado frame under my cj, I'm currently putting a 350 in it but my concept is a little different from yours..

That's a good point too. I forgot about the 208 having a slip yoke.

Unless your running a CV drive shaft, that is going to vibrate and spit U-joints like crazy. Pretty short as well.

What is the steering setup in the front? IIRC the drivers side knuckle had the boomerang arm on it and a short link to the steering gear box. Hopefully your doing cross over steering.

How about stretching it while ur at it? Wouldn't be a big deal, as far down as you are now. (if you have the resources, time and skills) Just asking. That would help the angles out alot. Is this just a mud runner, trail rig? Are you using the stock hangers (like I see in the pic) or outboarding? Just some other options for you to ponder

I'd still stretch the rear back some. When I go to full width's I'm going to move it back some.

I have the exact same driveline to put into my CJ, but I plan on stretching and linking the rears... it looks a little short and steep to me as well...

With the 350 and 205 it is a lot better of an angle and a LOT shorter than that 465 /208
