60 MPH? Woohoo!

enjoyed

A few side notes:

Normally cruising @60 mph would not be recommended in a 70+ year old car with babbitt main & rods, a 4.69 ratio differential, a 110 hp engine, and a body / frame combination that pushes 4500+ lbs. The original standard 4.69 ratio winds the engine close to 2900 rpm @60 mph.

A few modifications have been done to allow cruising at higher speeds. I replaced the original 4.69 ring & pinion with a 4.07 which drops the engine rpm from approx. 2900 to 2500, which is about 50 mph if the stock ratio was still installed.

The engine has been balanced to 0.1 grams to reduce as much as possible additional loading on the bearings due to reciprocating parts not being balanced.

I added needle bearing into all the rocker rollers, replacing the original brass sleeve bearings. Because the cam is geared at 1/2 the crankshaft speed any reduction in hp required to turn the cam is doubled at the crankshaft.

The mains and rods have been re-poured with nickle babbitt. Nickel Babbitt Alloy is the result of over sixty years constant effort to produce the best bearing alloy, regardless of cost. Today it stands supreme in the field of high-grade bearing metals. It is made only of carefully selected virgin materials and each element is subjected to scientific treatment during the alloying process.

Nickel Babbitt lasts longer under severe service, because,

* It holds the oil film
* It pours freely and fills all liner crevices
* It's anti-frictional
* It cannot cut the shaft
* It resists high temperatures
* It has high thermal conductivity

Regards,

Dave

Another drive....another time....
