Modified Hemi 4 speed ?

Modified Hemi 4 speed ? - 08/24/10 01:07 AM

I have a 1969 Cuda 440 with a Hemi 18 spline trans in it. I was wondering who here has modified one on the street with making it a crash box or face plating? I'm looking to redo the trans because I'm having shifting issues under high RPM and trans popping out of gear sometimes... I thought possibly going to a G-Force or Richmond 5sp. Please give me some input on what you guys have done or have had experience in the past.

Thanks
Rob

Hey Mike we spoke you'll be doing the trans I was getting some feedback. We have been both busy to catch up.

Do the face-plate on third and fourth at least
First and second can be slick or pro-shift.
I had my Richmond face-plated and it works perfectly

Did you run the car on the street also or just raced it?

I run it hard on the street and full throttle on the track leaving on the 2-step and it holds up well and doesn't miss a gear with a Long V-gate shifter.Make sure you get the HD Liberty modified side cover if you go with the 833 trans

what is the benefit of that side cover, less case flex?

I am currently just running an old school Hays MK XII plate and a Ram sprung hub bronze disc.It does good on the street but it bites too hard for the track.

I have the McCleod dual disc set up boy there is no slippage at all with that set up... I noticed when it heats up there is no easing out at a red light car just jumps off the line...

The cover is just a modified stock unit.The shift lever shafts are tool steel and they aren't machined for O-rings.They also have been upgraded with 3/8"threads for increased strength where you fasten the levers instead of the wimpy 5/16" stockers.The cover is machined for a positive lip seal that you can replace from the outside if it ever leaks

I love the one he did for me,, Shifts like a dream!! Get a nice Ramrod shifter and never think about a missed shift again!!

I had one in the car for a while until I started breaking sliders and gears,I split 2 third gear sliders and trimmed all the teeth off third gear before I realized it was too stiff for racing use with traction

Lol last time out at the track with the car was Oct 0f 2009 at a mopar event. Mind you I run a ford 9" with moser axles detroit locker. I dumped the clutch at 5k I broke the pinion yoke off the rear plus the u-joint. I was in shock when the pinion yoke broke off.. Now I have a spool with billet yoke and new drive shaft with 1350 jojnts. I doubt it will break again. I this the hemi 18 spline will hold up well...

Well I guess you are learning the first rule of stick racing,build it from the rear forward.I really would recommend an aftermarket carrier for that 9" like the Strange or Moser unit with a good pinion bearing support as well

Gus...how fast (ET and MPH) is your car?

How much to build a trans (clutch and all) similar to your setup?

Re: Modified Hemi 4 speed ? - 08/25/10 05:00 AM

What does it mean to face plate the gears. I just never herd doing that before

I haven't been able to hook it up yet on my one and only time at the track this summer but spinning through first gear it went 7.13 at 99.45 on a humid 92 degree day I don't know if thats any good or not,this was my first 1/8 mile race.
Plate was NOS E-bay $140.00
Flywheel used Hays 143 tooth $50.00
Richmond 5-Speed got from buddy $1900.00
Face-plate mods and cryo treat on the gears with me building the box $850.00
New Ram disc $180.00
Long V-gate shifter $525.00
Figure 400-800 misc for TO bearing,pilot,bell,yoke,shaft,mount,bolts etc.
Add an entire weekend for cutting and boxing the torsion crossmember,fabbing a new trans crossmember,clutch linkage etc...
Not a cheap drivetrain for sure

I guess I'm of the opinion that the best decision is to either decide whether the car is a street car that you race or a race car. Have raced with unmodified 833, 833 w/gear vendors od, tko, tko proshifted, and jerico. For dual purpose (read street mainly) the 833 w/gv was probably the best. Not great at high rpms (miss shifts on occasion) but was reliable. The TKO was OK when racing but seemed to miss more shifts same problem as the 833 w/r to shifting at higher rpms, but had the added feature of having 5th gear and every now & then would go from 2 to 5 (no such problem w/4spd). Had the tko proshifted and was great for about 50 passes. then grenaded 3rd, fixed, went another 50 passes then grenaded 3rd again, gave up & bought a used jerico - its great on the track. But sures takes the pleasure out of driving on the street. Can do but is annoying. So, bought a race car and transplanted the engine/trans from the 66 belvedere vert to a 68 barracuda. Will race w/68, putting the vert back on the road with the 833 and GV. My opinion is decide what you want it to be, race or street, and then do the best with what youhave. Took me a long time to decide. Good luck
