273 guys..Heads up!!!!

I used to use a dyno program on my computer but it won't work with my new 64 bit machine. Although it wasn't 100% accurate, you could at least compare modifications and see if they were worth the expense. I'm sure your rockers made a difference. The 273 chambers are small but efficient. The valves are small too and if they open farther it has to help make things more efficient. A comparrison on a dyno or a few trips down the drag strip would tell the tale. tmm
