Granny shifting not double clutching like you should

[@SquarebodyStuff]

It's a synchronized Trans, no need to double clutch.

[@sixtyfourchebby4507]

😅 Almost 25 years ago already....

[@spik3stactical]

​@SquarebodyStuff it's amazing the amount of people who think you still need to double clutch, that transmission came out in 1969 and has always been synchronized, I wish that habit would go away.

[@MattsMadnessOfficial]

Thats really cool , I used to cut every other syncro tooth off for faster shifts

[@SquarebodyStuff]

I've been planning on trying that later on. Once I get the shifter situation figured out. I've got several ideas brewing in my brain.

[@markk874]

At least you tried something bud. Most guys are too afraid to try something. Good video 👍😊

[@SquarebodyStuff]

Yeah, I'm not afraid to mess up. I'm not done yet. I got some more ideas.

[@thedriver02]

that was a pretty good idea, cant hurt for trying!

[@SquarebodyStuff]

Thanks, I think I just went to far. I'll probably try to build them back up and experiment some more on them.

Dang speaking of OG..you have 20+k subscribers now!!!

[@SquarebodyStuff]

I know, it crazy to think it's gone this far. I'm super thankful for every bit of it.

[@natevanlandingham1945]

@@SquarebodyStuff I can't remember when I got on board...if you were at 500 or 1500 when I subbed?

[@SquarebodyStuff]

It was early. I recognize your handle from way back.

[@workingmansrestorations7071]

I put my sm465 in mine to make it fun. I changed from th400 to sm465 and I am so happy till I hit 4th gear and it started grinding and shaking... I have another one to put in when I get time.

Always

[@stephenhester4118]

I've always liked those transmissions

[@thrashmarky]

I have a sticker on my toolbox I order from you on 07/29/22 had to look that up lol. Glad to see how well you’re doing. I saw you’re a vendor for my local classic truck show here in Gainesville Texas this year, might get to finally meet you this August!

[@SquarebodyStuff]

Awesome! We plan on dragging Squeaky down there and hanging out.

[@derricksmiley8293]

​@@SquarebodyStuffdo u have rebuild kit part number

[@SquarebodyStuff]

Not off the top of my head.

[@Chuck_S]

That's a big YES on the license plates!!

[@SquarebodyStuff]

I'll work on something

[@Tri-ZF450]

I don’t know how much you use granny low, but I wonder if you cut out the gears and put in place spacers along with cutting out the 1st gear shift fork would make it shift faster due to less rotational mass in the transmission along with less mass to move on the shift forks. I would think it might help, but awesome video. Finally someone giving the 465 some love!

[@SquarebodyStuff]

Thanks, I've thought about that, but then it's not a granny low any more. I still use it occasionally, it makes it easier to load on the trailer, and it's fun to see the looks on people's face when I get out of the truck and walk next to it idling along. I do ha e some ideas for lightening the insides on down the road.

[@workingmansrestorations7071]

My sm465 was seized when I put in. So I filled with atf and something else and soaked for a few days. But when I drained there was alot of brass flakes.

[@firstrespondergarage]

Awesome, good info

[@stephenhester4118]

Do you think a 750 holly double pump is too big for my 350 with a summit 1107 cam?

[@SquarebodyStuff]

I'm running one on this 339 with the same cam, and it likes it. If all you do is street cruising you could get better drivabelity with a 650. Depends on the application

[@stephenhester4118]

You're the reason I bought a 1107 cam

[@SquarebodyStuff]

Lol, awesome. I really like the cam. Good hot street cam that pulls good vacuum, is great for nitrous or boost, and most importantly, has a good chop to it. Lol

[@southgeorgia2099]

how hard to find a sm465 ?

[@SquarebodyStuff]

There's plenty out there. They were used in trucks from 68-91

[@southgeorgia2099]

oh ok that good to know ...@@SquarebodyStuff

[@natevanlandingham1945]

Yea there pretty common and bulletproof

[@SquarebodyStuff]

Not so bullet proof on my end. I've trashed a few through the years. But they will take more of a beating than any car 4 speed.

[@sixtyfourchebby4507]

@@SquarebodyStuff I drag raced a 465/20815 years ago... they break! I used atf, tried making a taller shift tower to shorten the throw.... they break! And back to stock 465s! Take care from the southern interior of BC Grumpy
