V8 cam, intake and carb swap +Random pics of 8600/1406/3731 going in...almost there!

Thanks man, looking forward to getting it out on the road. Should be good to go for the M&G in May. Probably still not painted then, but oh well...

Nice work, you're catching up to me fast.

So, what did ya do with the CTO?

So, what did ya do with the CTO?

It's still there, just not completely hooked up. I'm not at home right now or I could give you better details than that. I may take it off completely and plug the hole on the thermostat housing, not sure yet.

Kickdown Issues

the kickdown generally has about 1/4 throttle worth of slack. adjust it to be pulled fully forward at full throttle and you're done.

In an attempt to get everything ready to go for the DFW meet and greet in a couple days, I think my kickdown is the last thing that's necessary to make it over to Southlake. Anyway, it looks as though there won't be enough of the original kickdown piece to extend it out far enough to work properly. A question that I have about adjusting it is how far does the kickdown need to be pulled to work properly? With the factory piece, I can adjust it out enough to pull just a little bit on the kickdown, but it doesn't seem like it will be enough to do what it needs to do. At full throttle, does the kickdown need to be pulled as far as it will go? It seems like in order for that to happen, the carb needs to make contact with it immediately and start pulling as soon as the throttle is pulled, but I know there is supposed to be some throttle (about 1/4 according to Ristow above) travel prior to the kickdown being pulled. For now I am going to get a piece of heavy gauge wire or possibly a welding rod (stripped of the flux, of course) and make a new piece to replace the "trombone slide" piece of the kickdown that actually connects to the carb and wraps around the plastic bushing. I'll probably go ahead and order the Lokar soon too since it seems to be a little better of a solution.

Any insight would be appreciated. I have looked at the Tom Collins write up in the tech articles and read a ton of posts, but I'm still a bit stuck here. Thanks again as always!

Kickdown solution and latest question...

Here is what I came up with to extend the kickdown out far enough.



This is the original kickdown, my first attempt at making a new one, and the one that I ended up going with.





I went and picked up an acetylene rod and shaped it to replace the original. I put about 100 miles on the Jeep Saturday and she ran pretty good. I think I might need to adjust it a little more to get it just right, but that shouldn't be a problem.

Soooo...here's the question for the day. While the Jeep ran fairly well, especially since everything is tuned as it was out of the box, it did seem much more sluggish upon acceleration from standstill than I would have expected. I am thinking that since it runs so well at speed that it's not a timing issue, it seems like that would create a problem throughout the full range of throttle. I'm guessing that it's a vacuum issue, so I still need to go through that some more, deleting as much as possible along the way. Any insight on this issue (low power on take off)?

Oh yeah, here's how I fixed the hood latch mechanism I broke when disassembling. Not too techy, but oh well. And by the way, what a PAIN to put the hood back on by yourself...wow!!

Hood latch mechanism? Isn't it just a screw driver?

[Stumblinman]

I ditched all my hood latch stuff a while ago. Hood pins are so much easier.

Sluggish off the line huhh... I thought going with straight manifold vacuum was supposed to make it smoother. It could just be the idle mixture screws needing a little adjustment. What's your plugs look like ?
