If I were to have built the rear from scratch I would have bought 3.23s, but my core came with 3.08s. Didn't seem worth the money to jump one notch. Plus, I drove 75 mph down the highway too and from the track under 3000 RPM.

Another note, because I don't have a rev limiter, I shift fairly early to be safe. On the dyno we know my motor makes power up to 58-5900, but Ive been shifting at more like 5200. If I were to ring it all the way out, there might be a little more left still. Even these runs were a little harder on it, I ran a full MPH faster than I had before. Im also still a novice with real race tires. I have a total of maybe 7 passes with drag radials.

Ill do the 1/4 Injun Wars event @ Indy, other than that I will probably wait for a little cooler weather before I run again.

Also, Ive said it before, but another shout out to TSP converters. Mine is awesome.

Can you post a dyno sheet or if you have posted one a link to that thread?

There is a thread from me circa like 2016 or 17 with dyno numbers. Its kinda clunky to find on the search function, but I think I have it saved to favorites on my personal computer. Im leaving work now, Ill look it up from home in a couple hours if someone doesn't beat me to it.


The numbers were a best of 579HP and something like 590 FtLbs with a 2" spacer and a 1050 dominator house carb.


With no spacer and custom 850 Qjet, full exhaust, accessories and all I figure Im probably more like 540-550 HP.

I drove my 73 TA on the street for many years with a 3200 RPM stall converter. It was the best thing that helped my TA, until I started running 7" wide slicks at the track. That knocked a bunch off the ET's.

What does your exhaust system consist of? Does your car spin off the line or hook?

Dyno sheet thread. Cam info is a few posts down.


As for the exhaust, its Dougs longtubes for a roundport, down to 3" tubes all the way back with an X pipe. Magnaflow mufflers. This probably is a place im giving up a little power as its a common exhaust shop system. Its got a couple crush bends. I would like to redo the portion before the X's to have mandrel bends and maybe the gradual neck down header reducers. Once you get towards the back it probably doesnt matter much.


Traction is a little bit of both I guess. Hooking and spinning. Some of that is driver error im sure. Im new to the world of sticky tires. I made 5 runs on Friday, two 1.8s and three 2.0 60's. Some where i clearly heard or felt the tires come loose. Again, it was quite hot, and Im not 100% sure what PSI I should have the tires or how long to spend in the burnout box. So I dont know how good of info I can give there.

I would like to see 1.7 60's but the conditions werent optimal at all. Plus I have the 3.08s with a standard first gear th400. Its never going to pull the wheels off the ground.

I probably could launch a little harder? One of the last places on the car I havent strengthened is the yoke on the 8.5. Its still a 1310, though it does have a nice Spicer solid joint. When Im foot braking the converter I have visions to annihilating that U joint.

Keep working on your 60', bump up your shift points a bit and you will have your 7.90s. Then, you need more gear...then you need more cam....then you need some spray.....

Nice work, neat car.
