Kirkham Differential

[big-boss]

After ready this thread, you would think we are talking about Denise Rischards" rear end (very fine one I might add). The thrust and vitality makes me proud.

If I find a Kirkham with the alum. rearend fine- if I order I will use the jag I have had in the shop for ten years. I think the 9-in is a waste. Buy the time you pull it out and swap the center section it would be faster and easier with no mess to have an extra jag to swap in. Not only that it would look like a less expensive kit car from the bottom.

Jamo, The Velasco crank is waaaayy overkill for anything making less than 800hp, and I'm not sure how a $5200 Shelby block is better than a $3500 iron Genesis or an original block. I guess it all depends on who's writing the check, eh?

Just to be fair, I didn't buy an aluminum diff either, I got an IRS 9".

Assactly my point, my friend...folks have many reasonable alternatives in how they spend their "$70,000."

I was looking at a couple Jag third members on eBay and the sellers show them weighing 115 to 120 lbs by themselves. Is that correct?
Do they really weigh that much?

My Jag rear with mounts for the Kirkham was about 135#'s if I remember correctly.

I agree about the potential of an oil additive potentially atttacking the paint but it is/was common practice to paint the interior of blocks with Glyptal to seal the cast metal surface, perhaps it would be the better choice?.

I just took delivery of a Kirkham roller in Oct. and the diff is stamped "Auburn". I assume Auburn Gear Corp. Have to say I like what I got. Looks good, fits right. I figured since everyting else in the car was new I didn't like the idea of a used drivetrain component. Similar cost, I opted for a Tremec rather than a toploader for the "new" factor.
