Mr. Boss and Ron:

I have ordered a 4.30 : 1 gear. Will also install a line lock along with the 10" converter. The numbers you give, really help. I have been hesitant to run the car at the track. Have been asked why. i will not race it without making sure that my powder is dry. Will not damage the cars´ reputation with 13 second runs. I have used various Holleys on thses engines over the years. The 850 makes the best power overall, but the greatest throttle response came from a 750 DP.

I have one final question: Crane offered me two special grind solid 8620 steel roller cams for this engine. I took the cooler of the two, (214/222-,535/,565 at 1,7 ratio, but I wonder if I should order the other one. Its numbers are:

232° I / 240° E ,578 I / 598 E. How lopey will it become with this stick and what is the difference in power?

Thanks again.
