My goal is to get my '69 somewhat track day competent. Current 3:73 posi with Moser axles, 355 ci, 202 heads, GM "Duntov" cam, 650 Speed Demon, that comes to life around 3-3,500 rpm. Will the RS-5 600 close ratio gearing be a decent choice?
I had the car 21 years now and it's about time to increase her fun factor. |
Indeed! Check out the
complete solution HERE. I've attached a pic also.
Sounds like the Duntov cam is similar to the one used in the 327ci/365HP Corvette '63-67. I had a '65 Vette with this engine, and it liked to run above 3000rpm also. This motor will work exceptionally well with the RS500 deeper first gear. Those engines like to rev and can use the extra torque multiplication the lower first gear provides. That being said, the 2.80 first gear will motivate the car with less torque multiplication, but less drop in the 1-2. If you shift at 6500rpm, you'll be going 40mph with the RS400/500 and 48mph with the RS600.
Check out a really nice
gear speed calculator here. Use the ratios to compare the two for your application.
