'80 intake v/s '83 intake??? (258)

I recently but a 258 from an '83 CJ7 into my '80 and my old intake was a cast iron, the new one is an aluminum with water jacket and the little rods that stick up under the carb. Is the newer a significantly better intake? My linkage bracket does not bolt up to newer intake and is needed to maintain stock linkage for transmission kickdown (TF999). I think I may just go to cable on kickdown, as I'd think the cooler intake and better atomization were the goals in the redesign. Thanks for any info.

there isnt much difference between the two, power wise. weight savings is nice but for real performance gains go with something like CLIFFORD Research.

Mostly I'm thinking more about the linkage pivot that bolts to one intake but not the other.... and whether it's easier to swap intakes or get the Lokar kickdown cable...

If you swap the older intake back on you will also have to swap the old exhaust manifolt. The two versions are not compatible as the mounting shoulders of each are not the same size, among other things.

The cable would be easier work wise and the swap of both intake/exhaust would be easier on your wallet.

What trans do you have? If auto is it TF999? Does it use stock kickdown? I may just need the kickdown linkage from a '83, actually, as the linkage is there on '83 intake, just not in the right spot for my kickdown linkage.

Maybe up to '90 with I-6 and auto, then.

Keep us posted on how this turns out. I have nearly the same situation coming. I have an '84 engine that I'm going to rebuild and will be putting in a 1980 w/ TF999. Thanks and good luck.

Probably... I live at Independence and Shore...

I'd like to check out your CJ sometime. I'd like to get the 8.8 and am interested at how much difference the clifford is. Also, would love any advice on the MC2100 and HEI tuning. Hope to catch up with you on a trail somewhere, too. Are you in any of the local groups?

Got it all figured out pretty simple enough today. Basically, use the newer intake and exhaust and the link 'pivot' part for the newer setup, then find a matching link rod from a newer CJ with an auto. I think the one I got today was originally from a CJ8, but still the same concept, as it was one with a aluminum intake. I think someone said it's also the same in some YJ's, too.

For the most part, it's pretty simple. Look at the donor Jeep and see if the linkage bracket is bolted directly beneath the carb or if it is closer to the firewall, about half way between carb and #6 cylinder, I guess. Or, if the intake is aluminum and the trans is auto, grab the rod.

So there you have it, ladies and gentlemen... really major pain in the butt with total simple solution.
