Okay originally I was just going to build my AODE that I have in the car now, but yesterday I was talking to one of my friends down at the local tire shop and he was selling a C4 tanny off of his 66'(I think). He said he would sell it to me for $150. It has 133, XXX miles. He says it runs it just needs a good rebuild. I didn't know all the pros and cons of switching to a C4. I know it is a three speed and that it is a tough transmission. How does it do at the track and normal driving around town? If I get a positive response I will buy it in a couple days. Plus what goodies will I need to build the tanny with? And what do I need for the conversion?

Just did the swap on my car. I sold my T56 for a Trans King C4...billet servo, clutches, vasco input shaft, reverse manual valve body, transbrake....good for about 850hp, and I used a JW Bellhousing 157t and a JW flexplate 157t.
On the conversion besides dealing with all the shifter stuff (i removed my center console and put a new carpet kit in my car), but you can get a B&M Hammer shifter that will adapt to a C4 and will fit your console. You will need to make a plate to adapt from teh mount to the crossmember b/c the C4 mount is about 1.5in forward. I went with the badass Seatrab trans cooler as well. I'm using a B&M Pro Stick shifter also. I will have pics this weekend b/c I finished the swap two days ago.

Well this is a manual valve body so I have to shift it all the time. I rarely drive on the street anymore...I'm a True Street car that is about 95% track time. I have a PI converter but I'm afraid that what they built will be too tight for me...it's a 3000 stall. But I'll give it a try for awhile before sending it back to get it loosened up.

You need to downshift and upshift like a regular automatic would. A regular C4 you wouldn't have a manually shift it. I have a manual valvebody which makes me shift.

It like leaving in 3rd or 4th gear on a T5....so you'd need to go back down to 1st gear....just like a T5

I got to run it at the track once last year before they closed.But conditions were terrible compared to usual so I really couldnt compare the two yet.But it pulls just as good as the T-5,its easier to launch so far,and its concistent as hell.Before on drag radials and T-5 I ran 13.30s on 1.90s and the one time I did get to run the C-4 on drag radials it ran a 13.58 on 1.90s.I think with similar conditions it would run the same or better than with the T-5.I have no transbrake so im footbraking.Kinda wish I had got the transbrake.The tracks around here open next week so Ill be trying it again here in a couple of weeks.I cant wait cause im trying some different jets in my Zex kit.Tryin to see how close I can get to the 10s.If I hit 11.30s Ill be really happy.
