Update on the race car.
I did get the performance shifter installed and it made a HUGE improvement. Coupled with the shim under the shift fork ball and I'm able to get from 1st to 2nd to 3rd to 2nd, etc. with no problems. I ran the car at a couple of regional events before last weekend's Championship Tour in Ohio.
What has been a issue is minimum weight however. That minimum in SCCA Solo DP class is displacement = weight (2-valve per cylinder cars) so that put mine at 2056 lbs. without driver. Without any ballast, the car weighs 1638 lbs. That meant over 400 lbs. of ballast. So I added hot rolled steel plates (least expensive) in 12" x 12" chunks of 1" and 1/2" thickness. It took stacks to get that weight which I bolted to the floor pans. I ran the car 4 runs in that trim at a regional with a decent course. The car handled well but acceleration was poor. For the next heat, I took out all but one 1/2" plate on the passenger side for XP minimum of 1653 lbs. Quite the difference with very good acceleration. So I'm in XP now with a greater level of preparation for many different makes and models (including engine swops). Oh well, might as well just drive as best I can and have fun.
Here's some photos of the shifter, ballast, etc. And a link to one of my runs at the Champ Tour.
Also, I started in on a restoration project some of you may be interested in. An '82 924 Turbo that needed saving.
