Re: What Mighty Transmission will work?
Well, it began with a 1983 -232 block, bored out to .60 over, then forged/flat pistons, moly everything could get. Strong Competition cam with springs, lifters, etc. 1985 258 head-shaved .60. Large chevy stainless intake and exhaust values. Big block chevy moly pushrods. Significant milling and enlargement of intake and exhaust ports. Exhaust headers, flowthrough muffler. Enlarged exhaust system. Offenhauser intake and Holley 500 cfm, 4-bl carb, Jacobs electronic ignition. Holley electric fuel pump with indash regulator. Recently we drove it on the interstate - 300 miles at 70-75 miles per hour and it average 18.5 & 19 mpg each way. I suspect with some tuning of the carb we might be able to even add close to another 1 mpg to that. It is running 31" GoodRich ATs which it can turn. It idled rough and was a bit weak on the low end, until the Jacobs package. The electronic ignition really did help. Unfortunately, I have problems with the high output alternator and Jacobs system. It is currently a headache to shutoff. I tried the "resistors" provided by Jacobs, but they didn't work. Just getting ready to try install a 30 amp relay the sent with hopes that will address the shutoff problem.
We just did a complete body rebuild and used OMNI paints with a heavy violet pearl in the Grape II paint. My first attempt at fullscale base-clear coating. Only had to redo the hood. Very pleased with the price of the paint and the final outcome. (2 primer coats-1 sealer coat-4base coats with pearl-3clear coats with pearl-3 clear coats. Obviously had to buff out the overspray and some peeling.
Appreciated the comments on the Tranny. We had it out to Moab a couple of years ago and I think that we may have damaged the tranny in the heat and on some of the hill-overs.. The engine rebuild has just increased the sluggishness of the tranny. Most of the remainder of the CJ is still stock (Dana 200 Tcase-AMC 20 rear-Dana 35 front). It was a police tactical jeep, purchased from the factory so it did come with an apparent factory install optional tranny cooler? and air conditioner?
Our next projects involve - the tranny, transfer case, suspension, and axles.
Thanks for your comments
