Badrich,

Rallye Snake is very correct about the gussets that need to be added to the Jag rear end lower arms...this is regardless if your design uses trailing or, rare exception except for the Butler and I think? the Unique cars, trailing arms.

Your site moniker describes a KILLER 427, you Must get the best pieces for that engine, stub axles, half shafts, u-joints, outer spindles, etc. whether or not you are drag racing from a standing start...that sort of engine will tear the Jag control arms apart...the only thing you don't really have to worry about is the Salisbury/Dana gears, everything I read is they are bullet proff for most things, if they were sound to begin with.

The front end components, I dunno...but at the CWI, Concours West Industries web site they are building very strong front end arms to fit the Jag uprights and suspension pick up points.

If you think about the braking loads on the front A-arms, the speed that your engine could develope...do you want to run unreinforced 30 year old control arms ?

I have a CWI rear end in my ERA 289 car, my engine is hardly a a big FE...I have a 289 stroked to 357, mediocre cam...but I never wanted to break and screw around with anything in the drive train if only out of shear laziness, if not safety???!!! ha...

I got the gusseted lower control arms, the stub axles, positraction, and something else was beefed, maybe the outboard spindles...

Because I never wanted to rebuild the center section, I got the stub axles...the ventilated 0.875 discs to help with heat in a car that sees lots of open track, but stuck with the Girling rear calipers...could not rationalize the Wilwood's, but if you plan to opentrack/road race your big block car, that may be a good upgrade.

Some one said CWI is out of business...I do not know...I found them on the Web...the phone number as listed is:
360-274-3373, they are in CastleRock, WA...306 Dwight Road, 98611.

A fellow named Michael is the owner, he is English, generally pleasant depending on the last customer he dealt with, but I am happy.

Ther is another Jag rear end modifier, AMP Engineering, the owner is George...they are in S. California, very good shop, I do not know if they have a web site...do a google search.

My CWI rear end has 5200 miles on it, has been no problem at all...wish the hydraulic throw/out bearing was as dependable.

Please post your thoughts and experience after looking into this.

Like Rallye said, you really got to get some good stuff...especially with the super wazoo big block your are going to use.
