Bob congrats on your great first track outing with the Duster. The 557 cam works pretty Damn good say. I ran a bunch of 10.55 in the 1/4 with it in my old 3500 pound 65 Plymouth B Body. Keep up the great work and can't wait to hear your next new best et. Thanks Bobby, next year I might have to throw some gear in this thing just for one day

Well the season is over now, time for a long boring winter. I now have a grand total of 5 passes on the car with 3 trips to the track, added some weight with a mild steel 6point roll bar and harnesses. Still haven't had time or energy to do any real tuning but better air and dropping the jets down 2 numbers netted a nice time slip: 1.51 60 foot 6.78 at 100.99mph 10.69 at 124.65mph Drove it to and from the track 50 min away, and yes I'm having a blast with it! Still need to do more jetting, haven't touched the timing, and I have several things to do such as sealing the hood scoop, slightly tighten the converter that has 17.5% slip, and might try a good electric water pump. The 3.23 gears will stay forever.

If the street manors are good might leave the converter be. It is going to be hard to get the slip race car efficient with that big ole lever you got on the end of it. Just a thought. The tighter converter would widen the shift extencion and lower your trap rpm.
Getting old just means you were smarter than some and luckier than others.

The tighter converter would widen the shift extencion and lower your trap rpm. That's exactly what I'm debating over the winter. Normally with an 8" converter and 4.30 gears I expect about 3% slip out of my converter, but with this car having 3.23 gears and a 9.5" converter, I'm wondering if a little slip is helping it..? It drives great on the street and strip and the trans fluid is always red in color like new. I would not be very happy if I did all the work to remove the converter, pay to have it tightened up, and then the car slows down a tenth or two. Then again it might drive better on the street and it is 80% street driven.

I agree Doug. I was not aware of this till I started modifying later model cars with 2.79-3.23. A lot of the time the 2.79 geared cars were nearly or as fast as the higher geared cars. That low numerical gear really makes the converter work. The shift rpm will tighten up and you get more flash out of a tighter converter.

The 3.23 gears will stay forever. Hey I thought you were going to come try my 26"s next time out after the cage install. Glad you got her out one last time. Are you sure on the slip numbers?? Heres my math for your latest mph outing with the 28" tires and if you would of used my 26's. 124.65 x 3.23 x 336/28 = 4831 RPM. 124.65 x 3.23 x 336/26 = 5203 RPM Not really that much different really but in the right direction. My combo at that MPH would be at 5998 RPM. You stated you were crossing the stripe near 5000 RPM, I don't see any room for 17.5% slip.??

Wow you have that basic combo running great. We would be a good race of two street cars driven to the track. Its fun for me when I am done racing and all I have to do is put some air in my rear tires and drive home. And that while I watch most loading their cars on trailers. Its great as long as nothing breaks. Ron Yes we would be a fun race for sure Ron! I'm currently running cheapo radials on the street and changing to a different set of rear wheels at the track with M/T 275 Pro drag radials mounted on them. Next summer I may try some regular M/T drag radials so I can just leave them on the car for street and strip. My concern is that I drive this car so much, I might go through a set of drag radials too quickly on the street.
