Got the 391 in today...ATTN: RON !

[SuBLimE 69]

I was originally gonna PM this to Ron but It's been such a good day I'll share with everyone.

Ron, We got the rear end in today with NO DRAMA...everything went as planned.  I bought the unit from a guy on the forum awhile back...dont remember who but he gaave me a good price ...THANKS MAN !  It was set at 7k backlash so we threw it in and had to make no adjustments at all.  The old unit was identified as 323 suregrip which I had pretty much quessed.  I was very happy with the 391 before I even got out of the driveway.  The car doesnt work hard at all now to get moving.  That rear and the stall were a perfect match.  I used a stock MaMopar speedo cable (for 14 inch wheels) and It is nearly dead on the money maybe a mile per hour slow.  I could tell right away the car was alot more "torquey" right off the bat and I still have the regular ricer tires on the back but I got the nerve and let her breath.  I rolled through the stop sign..(with a dozen people watching from the gas station)  all it took was the guy in the HEMI Ram to give me the thumbs up and I was gone.  From a roll at about 2k I hit it, the tires broke loose and she fished to the left slightly, I hit second still spinning and gaining ALOT of speed, she carried back so center and fished back right until the tires finnaly grabbed but then it was time for third.  I hit third all HOLLY SHET if they didnt spin again when I hit third.  I lifted since most of the seat had been sucked up my ass and decided I need to act like a citizen again. 
I think the gear is just deep enough to still be very streetable.  I think the 411 would have been the obvious choice for the track but I wanted a driver so I happy happy with this one so far.  the 323 was a heck of a cruiser gear but the stall converter just didnt like it.  The drag radials should be mounted next weekend and then I need to get my sub frames welded in.  Next, I have got to order the CalTracs and Mono leafs or find something that might work better/cheaper.

Its been a real good day at the Sublime house.  Anyone need a great condition 323 sure grip that doenst make a lick of noise get a PM to me.  I'm sure it'll go fast.

great to hear sub! sounded awesome, wheres the vid?   

I had 3.91's in my charger and at 55mph it was 2800 rpm  bye bye gas hehe.

oh and you got a pm hehe

[firefighter3931]

Excellent ! The 3.91-4.10's are a nice match to the TA 10in tight converter....i knew you'd like that combo.   The cam, converter, intake/exhaust and rear end gearing/tire diameter are all well matched for this car, i wouldn't change a thing once the 28in tires are mounted.

The 28in drag radials will knock some gear out of the final drive ratio. It will be a 3.63 final drive so your speedo will need a new gear to correct for mph and odometer. Those are ~ $10.00 at the dealer and are a snap to install.   I did some cruising speed calculations using an online calculator with the 28in tire/3.91 combo :

60mph = 2800
65mph = 3050
70mph = 3280

**If you really wanted to make it a "highway star" and install a gear vendors overdrive the #'s would look like :

60mph = 2200
65mph = 2400
70mph = 2560
75mph = 2750
80mph = 2920

Nice to hear you're behaving yourself in front of all those ordinary citizens.     Congrats Doug, it's allways nice when a plan comes together  

Ron


Ps. If you need a pn for the speedo gear just say the word and i'll dig it up.

I am not sure how much freeway driving you are planning on doing, but I drive mine over
a 100 miles to some car shows and I am seriously thinking of going back to my 391's now has
355's but the car really likes the 391's for sure. Anyway I am looking into the overdrive but
I would like to know how many mods I will need to do to make it work??

Sorry I don't mean to take away from your thread congrats    and I could use those 323's in
another car of mine

Dan, I have a website saved on my computer that is an install of a Gear Vendors unit in a '69 Charger, I believe John Schneider's General Lee. I won't be home untill later tonight but am more than happy to post it.

Oh Doug, I believe the part number of the speedo gear that you need is 2538937. I took that part number right off this section on mymopar.com, http://www.mymopar.com/speedometer.htm . Good luck !

Sounds great Sub, I can't wait for this hot stuff to calm down here so I can get back to it myself.. It's been a very long hot summer this year..

Have you put together a spec sheet for your car yet??  I'd love to see it..
