Ordered my 426 block today! Transmission???

[Mopar_1971]

After months of searching, I finally found a 426 block today. Excited doesn't even begin to describe it!! I know for sure that I want a manual transmission, 4, 5, or 6 speed is fine with me; but what is recommended/what will work with this motor? Thanks guys!

4 or 5 speed is probably best. 6spds were designed to be emmissions trannys, less particulates per mile, with double over drives. the 6spd won't hurt anything but probably isn't worth spending any extra money on.

426 what? and whats it going in?

 

[HEMI-ITIS]

What size tire under the back???

 

[Deleted member 214]

426 wedge or hemi? Stock or modified? Cruise or race? I've got a 5-speed behind my 440+6 cruiser and wouldn't have it any other way.

It's a 426 hemi block, going in a 1971 Charger. Street, no race, shooting for pretty much stock aside from a nice cam to make her "slobber." Haven't decided on tire size yet, but I'm definitely thinking a modern look; big wheels (18/20") with wide tires. Celica? Seriously?!

 

[Malicious]

The celica suggestion is serious. But I'd go for a Supra box over a celica. Quick break down:

RWD celicas from early 80's to very early 90's use the W series gear box. The one to go for is the W58. The other W55-W57 have different ratios, different sized splines etc.

early 81-86 supras also ran the W58 behind the 5M-GE engine,

86-92 supras used the W58 behind the NA 3lt (7M-GE), while the same years turbo 3lt (7M-GTE) used the R154 bigger arguably stronger box. The R series box's were also used in some 4x4's (inc. Trucks as you guys call them), usually the R151-2, the input spline is shorter in these, so avoid them.

92+ supras (jelly bean looking one) used the W58 in the 3lt NA (2JZ-GE) is arguably the strongest of the W58's. While the twin turbo's (2JZ-GTE) uses the Getrag V160 6-speed. Very tough box, but I doubt you'll find an adapter to suit a mopar. Could be wrong tho.

Things to look out for are worn syncros on 2nd gear and reverse on both the W58 and R154 boxes.

HTH's

Holy Crap! and here i thought y'all were bein' sarcastic!

I must be stuck in the 70's because a Celica 5 spd from that era would not be my first choice in your application.

You beat me to it.

I'm sure Rusty can find another one or maybe I'll find him one on a street corner. Hey, car parts show up on street corners in CA.

Nothing like uncrating a new hemi block!

 

[snakeoil24]

Make sure you bought the 5100 series block and not the earlier. Also keep in mind the cylinder walls are very very hard. Need diamond impregnated honing stones.

 

[Moparmatt72]

Those supra trannys are stout. Considering most of them make 1000hp easy, heck the bottom end is good upto 800hp I heard stock. Course getting a bell housing custom made will cost a bit but would handle the hemi. If I were ever to get a import it would be a supra dont worry everyone im sticking to domestic mopars.

 

[Bigal75]

Which block did you get?

 

[RustyRatRod]

I wanna see the Celica box in it from a strictly carnage point of view.

 

[rev.ronnie]

I have not had any problems honing any of the blocks with silicon carbide, even aluminum blocks with ductile liners. Diamond stones do make the job go faster for sure, I can't argue with that.

The most important thing is to make sure the surface parameters are correct. The "deep hatch" marks that retain oil are very important. Discuss this with your machinest.

Here is an informative article on the subject.
