At this time my 69RR has a John Cope CRT-4(VMRVB).
Am very happy with it sofar.

For next winter I am planning on going manual trans.

Problem now is which do I buy.

Hemi has 750hp and about 600ft-lbs (pro-charger upgrade in future).

Really like to have an overdrive and good street use (downshift).
Also like to have Vertical gate shifter.

Called McLeod about their new trans but has 500 ft-lbs limit.

Called G-Force about their GF5R with Vgate shifter but no syncro in this box.
Also their Street 6-speed is a great trans but no Vgate shifter.
Liberty is also no street trans.

Any tips.

If production ever increased, I would use a Passon 5 speed Hemi box for your application. Your 600 ft-lbs engine torque is only relevant if you are putting all of it to the ground. If you are racing on slicks it might be more critical, but I am guessing that this is a street car since you want a syncro box. I'm still using the same hemi box in my 'Cuda since the mid 1980's and my car has run high 9's. The new motor will push it into the 8's and I'm planning on using the same trans, just different clutch setup.

From G-force website on face-tooth design:

Clutch assisted transmissions can be upshifted and downshifted quickly at ANY engine RPM! Part-throttle shifts can be accomplished without the use of the clutch simply by slightly letting off on the gas, ("blipping" the throttle), while moving the shift handle. Wide-open throttle shifting requires disengaging the clutch just long enough to release the load to engagement lugs. Once you've pulled the shift handle far enough to get out of gear, you don't need the clutch disengaged to engage the next gear. This is a significant improvement over the old Pro-Shifted design engagement. The transmission shifts very similar to a motorcycle in the way it operates inside.

Maybe you don't need syncro's. I have always wanted to try a GF5R in my car.

ST1200?

Thanks for the info RTSE4ME , but in same Gforce info they state :

Because of the unique engagement system of a clutchless G-Force, the transmission is not suitable for the street and will pop out of gear under deceleration. Since the clutchless G-Force is not a planetary transmission, it doesn't impose the same type of power losses.

The Viper based 6 speed would do it except no V gate. The Lenco would be fun. I'm pretty sure either of these would require fabbing a new T bar cross member.

Back when the Verti Gate shifters first came out I heard a lot of racers hating them, I tried driving a freinds car for him and I didn't like it either The Long shifters where much better according to the guys that had them Look around and see if you can locate one of them in decent shape that is based on you not driving a car with one of them in it If you have driven one and like them then go for it

Gforce dogring boxes do not kick gear out on decel. Although beeing non synchronized i think it would get boring kinda fast.
But if you could live with that i would say its perfectly street able.

They make GF5R in 2 version cluthless and clutch assisted. The clutch assisted version does not pop out of gear under deceleration and can be driven on the street. The difference betwwen the two are the sliders and face plates on 1st thru 4th gears.

I don't get how the McLeod can only hold 500 lbs TQ? An 833 hemi box will do way more than that.

Guess I need to see what they made.

My car is set up with a V-gate. I like V-gates over H pattern shifters. Besides being different, I have seen people (Not me!) pull wrong gears with an H pattern shifter. I have had people drive my car, and no one has ever missed a proper shift. Never had the opportunity to use a Long style.

Yup, I used a Vetrigate on the street all through the 1980's. There would be one in my DD if I wanted to cut the crap out of the floor.

I can't see a 45 year old production transmission holding as much power as a modern day box from McLeod.

Thanks RTSE . Did not know about the 2 differences GForce has with GF5R trans.
Will need to get back to GForce then.

Madscientist . Mailed with McLeod about trans as they state max 500 lbs and in MoparMoscleMagazine it's 600 and in their Hemicuda (art morrison framed 528 ProCharger) it's linked to 1000 lbs.
They say safe limit 500. They'r Cuda is not used with full power.

Yes. No sence in running a clutchless on the street.
I run a gf4a in my racecar and i would say its street able.

V-gates are a PITA to downshift, ya sure wouldn't want to autocross with one !!! Just my 2 cents !!

Jericho offers a road race version that might work for you.

I have a Lenco ST1200 on order in a 5spd with a 3.10:1 first gear and 1:1 in 5th gear. I also ordered it with the heavy duty sprags.

I will try not to butcher up the tunnel too bad (I hope), but I have a feeling that it is going to take some major fitting behind a lakwood bell housing. Tim Hyatt is building the clutch/flywheel for me too.

Another thing I am going to do is also order the Passon 5spd, and my understanding it is 2 years out on order backlog...but I figure I will install that if the ST1200 is not street-able enough.

As soon as I start the install I will post pics of the progress. I have to wait until March to start the project because of recent spine/fusion surgery...I can't wait to get started!

I've been running a Richmond 5-speed with a Long V-gate for the last 8 years and I'm finally tired of pulling the trigger when downshifting when slow cruising. I had Liberty's face plate 1st through 4th and left 5th syncronized. I love to drag race this box but with a V-gate and face-plate it's a little tricky to hit the down shift just right when street driving.
I have recently installed a street HEMI box with a good old reliable Hurst Supershifter III for easier street driving.

If you can find a Richmond 5-speed with a Mopar input I would highly recommend that box.
Oh and be prepared to do some floor cutting and torsion bar crossmember mods to make it fit with a V-gate because they are big.
