Chevy Engine Build Part 26 - The Pinnacle Of Performance

More Camshaft Gives DM 580 Hp And 514 Ft-Lb TQ!

By Mike Petralia

Note that the power for T42 does not begin until 3600 rpm. We had some difficulty loading the engine that low in last month's test. But this month, DM had no trouble pulling down there so we were able to get some power figures in the lower RPM range. As we said last month, "sometimes the dyno does not act like a car". But, now we know that if this engine were in a car, it'd be able to accelerate strongly from well below 3,500 rpm.

We're always looking for new ideas. Do you have a better one for Danger Mouse? Send your test suggestions to:
