B & M makes a reclaibration kit that includes an assortment of springs and weights that should do the trick. Clay

Im going to do that later tonight will post. I got a used governor that had some different springs in it.And the guy said this should make it shift were i want it.

Does the rear end gears have anything to do with that? (im running 323's)

The transmission balances the fluid pressure of the governor vs. either the modulator or TV in your case. Governor pressure is based on the transmission output shaft rpm and is independent of the rear gear. Rear gear ratio could have some effect on part throttle shift points I imagine due to a slight change in load that would result in a different TV or modulator pressure. Clay

Have you tried the different springs? You can also remove more weight from the supplied weights and the trans will shift at a higher rpm.

Just put the b&m reclaibration kit in and it reved about 7200rpm and now i have to let off the gas for it to go in to 2nd so im going to change the spring to the next step and see what happens.

the car wants to move when it hits 3600rpms,Leaves out the hole like a turtle do u think that the gears have alot to do with this?

Don't expect to get the governor setup in one try - or even 3 or 4 tries. I played with mine for a while and said the heck with it and moved on to something else. The 3.06 low gear in the 700R4 will help, but like af2 said, that's a LOT of weight to get moving, I think you need 3.73's or even better 4.11's. This will be a heck of a low gear, but you have a ton (actually probably 3 tons) of weight to get rolling. Clay

i was thinking of going with 488 gears just cause im running 22s=to a 28inch tire size and i had 456s before on my 95 impala and i figure a lil more wouldn't hurt since the caddy is heavyer

Hey BrooKLyn... Have you explored if any modern rear axle can be transplanted to the '64 Caddy? -With not too much trouble-

I have a couple of those cars both with 700R4s and with the stock rear axle and I do not like them, would prefer some higher ratio and available from wreckyards, rear discs preferred.
