In talking with Jay about cam selection he recommended I look at the way I drive. Am I interested in getting the car to the highest top speed possible? Do I short shift or wind it out to the red line. What are the actual RPM I am pulling at 60 mph, and I want to accelerate to say 70 mph?

The 1.7 I have in there now is good for about 90 mph and I don't really need to go much faster than that. I do tend to wind the car out to the 5,800 RPM limit, but that has more to do with the low power the car has right now. At 60 mph I am pulling 3200 rpm in 5th gear and 3800 in 4th.

I talked with Ron Iskenderian at Isky cams. They have two different cams for hydraulic lifters, a "torquer" and a "combination." He says the torque band for the "torquer" is 2000 - 5800 rpm and the "combination about 350 to 400 rpm higher. He says that the "combination" has a rougher idle than the "troquer" and that he prefers the latter because of that.

From the information I have gathered, I feel the ISKY "Torquer" cam #485122 is the best match for my objectives.

Jay called me the second week in November saying he is getting ready to do the machining and balance work on my engine, and we agreed that I would obtain the cam and clutch parts to complete the engine. The cam order came in as follows:

8 chrome moly pushrod tubes.......V-003..............$....60
"Torquer" cam.............................485122.................145
8 hydraulic lifters.........................4852-HY.................96
Valve springs................................205-G8..................28
Freight & tax...............................................................66
Total....................................................................$...395

The same week I got the Sachs clutch kit from 914motorsport for $238 delivered.
