Well this particular Toploader was about 13"....but the tailhousings vary depending on which model you get.

For me, the Toploader (alu case, D. Kee )is Number One. For my RAM, with a short ratio alu Toploader 4 speeds and a 2.88 Jag diff, I feel quite happy on the road with a speed of 80 mph at 2200 rpm and 17" wheels. And I have so much power (torque) with the 482 cu.in. that it is efficient for drag in street category.

Interesting, thanks Brent. It looks like there is a lot of difference in mount locations. I've got to get this right from the beginning, so more research!

Be careful which Richmond!
I have a Richmond 5-speed Road Race in my ERA FIA with a 3.08 rear-end. This tranny has a 1:1 final. I originally wanted the Richmond Super Street 5-speed with overdrive, but learned from ERA that the shifter doesn't really fit in a Cobra: they said that the installation would sit very high and look like something more appropriate for Herman Munster!
I had thought about a 2.88 rear for a little better cruising RPM, but Rick Lake cautioned me that the stud-axles were a little weaker with that set-up, so I settled on the 3.08. Haven't had it on the road yet, but Jim Holden (who has had several ERAs) had this combo in his FIA and said it was perfect.

Going slightly sideways here...Jeff, does your Richmond RoadRace have 27/31 cluster (3.01 first gear) or 22/37 cluster (4.41 first gear)? These give overall ratios for first gear, with a 3.08 rear, of 9.27 and 13.58. (I'm trying to relate it to a WR Toploader with a 3.08 rear)
Isn't your car red, not black?

I'm pretty sure it was the 22/37 cluster (which is for a Ford) with the 3.04 first gear.
Traveling today, tomorrow I can check for sure and give you the other ratios.
I had it repainted.

Glen and Larry-
Just in case you are interested, I chose the following gear ratios with my Richmond Road Race:
1st: 3.04
2nd: 2.13
3rd: 1.57
4th: 1.24
5th: 1:1
Rear-end is 3.07.

Thanks Jeff.
I am thinking of the same rear end ration with a WR Toploader, so my first gear o/a would be 2.78 x 3.07 = 8.56 whereas yours is 3.04 x 3.07 = 9.33
Same ball park
Cheers,
Glen |
