Looking good. Be sure to make a post on when you are going to the track (Bradenton, or Sunshine ), i'm in need of an excuse to go and play and get some runs in and hopefully get some better #'s. This cooler weather should be great...
Planning on installing the electrical water pump tonight. I'll also install the trans temperature gauge. I also might start to fabricate sheet aluminum covers for the cuts around the rollbar and for where my heater used to be..
Well, I'm running open 4 inch side exhaust... Someone might call the police on me...
I wouldn't doubt it. You should've heard my motor when it was in his car. 4" open side pipes! I don't think my open headers were as loud because at least they are under the car!
His new motor has a few more cubes to make noise with!
That might still be a few weeks away.. I'm waiting for Tom's 12-bolt setup which I got through Van Steel..
February's HOT ROD magazine has an interesting article called Taxing the IRS. They describe in detail some of the modifications made by Tom's Diff's. There are some good before and after pics of internal components, describing where each piece was modified.

It has to do with the hardness of the cam gear. If I remember correctly if it is a billit or hard steel cam gear you had to run the bronze gear; other wise it would chew up the distributor gear. That was the compromise you had to make to run a roller cam. That has since changed with softer distributor gears (iron) on less aggresive roller cams. With the poly gear you can run the agresssive ramps and it will not wear.
I was sceptical a plastic gear would wear like it does; but mine has lasted very well with .650+ lift and 7000 rpms.
