Housing girdle for 8.75"; yes, or no?

treessavoy · 03-07-2010, 07:12 PM

I ran a stock 8 3/4 with 11 inch slicks and a Max Wedge for years in the NMCA and never had any problems but I think you'll need to get Mopar SS springs or Calvert springs.

If you run Chrysler S/S springs you will need to redo the spring hangers
to get the pinion angle correct. Spacer wedges only do so much.

I now have another 8-3/4 housing with the back brace and the spring pads
redone to correct that problem.

Phil,
We are putting replacement spring pads on the housing, (I know, that's not hangers) and will try to get the pinion angle correct at that time. I said TRY... lol!

Thanks for the advice!!!

Bill, I stand corrected, it is the spring pads that get changed NOT the hangers.
I had a "B" body 8-3/4 housing cut down to stock "A" body width added a back
brace and new spring pads, just need to swap housings in the car.

Jim, we're hoping that with a 2,400-pound (sans driver) car, the stock springs may be okay with the Cal Tracs.

I wonder if we can use this stock, 170c.i.d. /6 converter with our 30-pound boost turbocharged 225?

Any ideas???

Bill,

I've heard of people doing just that but have no experience myself. At thirty lbs I would be cautious with the converter especially on burnouts, rather than leaning on the converter I would flash it on launches. Should be adequate for the street.

Good luck,

Jim,

This little 225 turbo /6 will never see the street.
It's just a hobby/race car.

Would you, or anybody else, for that matter, happen to know what diameter this 170 converter is?

It's still attached to the engine in the car (with the transmission) so, I can't measure it, but I heard it was an 11" converter, just like the rest of them (318/340, etc.)

I'd sure be interested to know.

Guess I'll find out when I pull it out.

10.75 with a small hub... be careful all the early 225/170 have a small 1.51 pilot hub instead of 1.66 Hub used on most anything else. Check your crank and converter to makes sure compatible..... also spline count changed to 24 around 67/68 as I recall. Hope this helps... early Mopar stuff is confusing.

I have cut open and reworked 6 cylinder convertor and used them small bolt and all on my Super Street and Pro Bracket Cars as heavy as 3500lbs even with small 5/16 Bolts. The 6 cylinder and 318/340 converters are both 10.75
Diameter but 6 cylinder converter cover is totally rounded while others all have a flat area around 3/8 inch on top furthest from ring gear... this is probably more than you ever want to know

BTW: Was not on Drinking Binge as some guessed 12/09 to 2/10.....Major Cancer surgery instead as a lot of people already know .....Would have preferred Drinking Binge for sure.

John knows his stuff. The hub and spline change was in '67, anything after that is not compatible with the early stuff without a crank change.
