A tip,,, never try to power shift the 465!!! The syncros can't handle trying to match up 300 pounds of gears that fast!

I wouldn't think putting a nearly 400 pound cast iron transmission into a car that has almost any transmission possible with nearly half the weight would be of any benefit, and the first gear of the 465 is NOT synchronized.

Unless you want to tow an immensly heavy load or something, this isn't a transmission that belongs in any car.

Yeah, "SM465" had "quick shift" put on a restraining order. Those two phrases aren't allowed in the same thread.

I think you might able to find a SHORT throw shifter for it, but the speed of the shifts has to do with the effectiveness of the synchros vs. the weight and ratio of the gears, not the shifter.

I've never heard of or seen one. If they did make one, I'd have it by now.

I am looking into fixing the loose shifter insert on my 465, and this will allow me to reduce the almost -inch of play that exists in the shifter, and should result in shorter shifter throws, but it's still a 6.55 to 1 non synchronized first gear and I don't think there enough power in front of it to get the 6300 pound Suburban to the point of being able to power shift.

I really wouldn't think a shift fork that weighs almost 2 pounds (have you seen one of these in a 465 lately?) would want to move very fast.

I don't remember any other top loader in a GM other than the 420 and that one had en even steeper first gear ratio.

the SM420 has a 6.699 1st gear I think.

thanks, i'll quit looking. if you search google you can find a fix for your sloppy shifting but that's about it. it's still going to be a slug
