Hello all! I'm new here, and have been checking things out. Cool site! Anyway, I'm getting ready to pull the trigger on a Strange S60 swap in my '77 Charger. I'm also going to get the larger yoke driveshaft from them. Does anyone know if the shaft length is the same when going from a 9-1/4 to the Dana 60?
 
Well, I never did get an answer, but it did wind up a tad shorter (1-3/8" IIRC). I know it's resurrecting an ancient thread, but I thought I'd just follow up now that the deed is done. It's a 3.54 geared Strange S60 Dana with 35 spline axles and a spool. Also a custom 4" driveshaft with 1350 U-joints and a moly yoke. The rearend is hung with a CalTracs traction bar setup and monoleaf springs (w 1" drop), and Calvert adj. racing shocks. We reinforced the torque boxes, and even fabbed up some brackets to keep the stock rear swaybar for now. I'm gonna try it out both ways, with and without. I also changed over to Wilwood discs back there.

So far it's been great, what little I've gotten to drive it (the engine went south shortly after). One thing I was impressed with is how little you notice the spool on the street. I had always heard they were unstreetable, and was going to go with a locker, but was I talked into this by my buddy that runs the shop I used to work at. It's totally fine. In anything other than a super slow hard turn (like backing out of a driveway), you wouldn't even know it was there.

The engine is back in now, so if Spring would just get here already, I could hammer down on it to see what kind of launches I can dial in on this boat!

Well, I had some more photos of the rearend setup when it was on the lift, but I can't seem to locate them right now. I'll get 'em on here when I do. Until then, here are some recent shots of it from the last time I had it out, when we finally got the motor back in.

Wow. Beautiful engine compartment.

Engine details please!
 
Nice lookin rig! Is this mainly a street car and if so, how are you liking that spool so far?
 
Thanks for the update. I thought the 9 1/4 was pretty good on it's own, but you look like you're really going all out with your combo! Nice.
 
Thanks guys! It has always been a street/strip/show car, but in the past few years I have definitely turned it more towards the strip, with my ultimate goal to get this land yacht into the tens. I added the Dana and cage last year because it was already running mid 11's with iron heads, small headers, and a 3.21 geared Sure-grip. I'm still not sure how that rear survived those launches with ET Streets in this porker, but it did! :icon_eek: Still, since then I had added alum. heads (ported Stage 6), proper headers (TTI 2"/3-1/2"), Crane 1.6 roller rockers, and meth injection, so the poor thing was definitely on borrowed time!

About the time I got it all back together last year, the engine started having oil pressure issues (see the "Dodged a huge bullet" thread for all that) so out it came for freshening. It's basically a 469" low deck stoker with Eagle rods and Ross pistons, using an old Comp custom ground 280/288 hyd. cam. While it was out I had the pistons coated, and replaced the old welded factory stroker crank with a proper 4340 piece. I also added a main cap girdle setup, and converted it over to an external oiling system with a larger pan and billet pump.

Since adding all that beef without actually throwing more power at this thing would be sacrilege :laughing7:, I also replaced the ancient Procharger D1X blower with a new F1C unit. Which then blows through a custom intercooler and into a modded 800 Race Demon carb, and ported M1 single plane intake. It's all fired by a MSD billet distributor and Digital 7+ box.

All that runs through a beefed 727 with a custom 10" Dynamic converter back to the new rearend setup. And Cranky, I will say that the spool setup back there was definitely the right choice! Although I have limited street time with it, 95% of the time you don't even know it's there. The only time you do is in a very slow speed, parking space type maneuver. And even then it's only a slight shudder, a little tire squeak, and a bit more effort on the steering wheel. Maybe with lesser axles I might be a bit worried about some twisting, but not with these. All in all, I'll take it!

Preliminary driving results are very positive. It is just a MUCH stronger combo! If this darn weather ever breaks, I can get some miles on it and get it to the dyno for some tuning. I am hoping that once that happens, those 10's are finally mine! :icon_super:
