[Fot] Initial Report Custom Chevy Con-Rod Transplant

[N197TR4 at cs.com]

List.

We have not dropped the pan yet, for inspection of bearings, but the Uncle 
Jack Chevy Con-Rod Transplant seemed to work very well in our TR4

Developed by Uncle Jack and Christian Marx, it appears to be a great 
alternative to the expensive Carillos. Christian has over 1500 miles of track and 
street driving on his variation of this transplant. I have nearly 200 miles of 
full throttle racing at Road America, last weekend.

It requires spacers for the pin end to centralize the rod on the journal. The 
crankshaft needs to be reground to a Chevy Spec.

It uses Clevite 77 bearings at an effective cost per four cylinder set of 
about $12.50 per set.

With the narrower con-rod, it requires a slight boost in oil pressure of 
about 10 lbs.

It is not known if Uncle Jack is going to proceed with packaging these 
con-rods for sale. One of the wrinkles is that spacers may vary in length according 
to brands of pistons.

I am pleased at this point, and will report the condition of the bearings 
when we drop the pan to inspect.
