Back in the day...…….. before even Todd Wheeler dreamed of a dog engagement gearbox conversion for a spridget, BMC sold a kit of straight cut (not helical) gears for SCCA road racing. Trying confirm those ratios...….I know 4th was 1:1 just like the ribbed case helical gear set. Help. Thanks, Jay

never mind……..I found them. 2.753, 1.722, 1.255, 1.00. Wow were those ratios lousy. In my bugeye dog engagement gear box I selected a 1.500 first gear...……...halfway between 2nd and 3rd on the factory BL straight cut racing ratios. Technology has really changed.

And, it was a non-syncro 1st gear, made of glass.

I broke my webster box at Mid Ohio and the only thing I had was a Leyland straight cut gear box. I put it in the car for the race and was amazed at how good it was. It actually seemed to have better ratios than my dog box. Only time I ever used the box. It's still sitting on the shelf at home waiting for someone who can't live without it!

BTW, when I first started running the Chimney Rock Hill Climb, the only gear box we had was a Leyland straight cut box. And we did do standing starts and had to crash it back into first a couple of times each run. Later I ran with a webster box. Gearing was better but it was brutal doing a standing start. Always loved the Chimney Rock drivers statement quote--- Chimney Rock scares me and I am fearless! Found a 1974 program the other day. Brought back great memories.

My Father was one of the starters for the Chimney Rock hill climb back in the earlier days.
