Quote from: "Ziptar"Quote from: "53 willys"I was using the RPM calculator and it seems like the ASF or same ratio trannys are the way to go....I would be doing 3712rpm@75mph with the stock 2Y trans...if I swap to a ASF or similar it would be 3059rpm@75mph ....none of the other trannys have any thing as good as the ASF....I wouldn't take the calculator as gospel, have a look at this I took that somewhere near Baltimore on I95 when I drove up from Florida, Its the ASF trans with a set of 195/60-14 Michelin Pilot Exalto A/S tires I had put on just before leaving Fla.The RPM calculator says I should be at 2989 RPM at 75MPH. At 75MPH I am ~2750 and don't get close to 3000 until 80. I suppose my Speedo could be off by a few MPH and maybe there is a margin of error.If I swap in a 0.71 5th gear it'll drop the RPMs about ~160 at 75MPH.I picked up a ASF today at the pick n pull for $65...how hard is it to swap to a .71 5th gear??
