Default Gear ratios

I havent seen an ERA in the flesh, and wonder at times why ERA isnt considered with the big three, Shelby, Kirkham, SPF, but I would emagine ERA is good value for the dollar!

Gear ratios, I picked 2.953 for my first gear ratio in a Jerico five speed, as this gives me a good launch gear for road racing, this is with 25.6 diameter tires, through a 3.27, 8.8" rear, my other ratios (4) are custom designed to suit the tracks here, but arent that disimilar to the Richmond five speed ratios! Having a lower first gear is great because you can launch it, grab second at the lower end of the power band, and they seem to be easier to get off the line, than eg 2.32 toploader ratios, where it is necessary to get a good balance of rpms with the clutch release!
