400 Build #2

I have been playing with the dyno program on the computer. Here is an interesting comparison of the 351C with everything the same to the 400 stroked to 427:

Here is the comparison of peak HP/TQ:
Tq:
400-Peak TQ 518ftlbs @ 4,000
351-Peak TQ 440ftlbs @ 4,500

Hp:
400-Peak HP 497 @ 6,000
351-Peak HP 468 @ 7,500

The interesting part is the rpm shift where the HP and TQ peaked. The tq peaked at 500rpm less and the HP peaked at 1500 rpm less. Some of this is due to the stroking and some due to the increase in cubes. I had always heard that Nascar engines are imposible to drive on the streat because of the RPM's required to get them going BUT if you increase the Cubes you can use the power because it drops the power band. (not to mention the aditional power).
