Hi people,
The biggest lump of iron that I.H. ever made was a 547" back in the '50's
It made all others look small. The later 345" was also a hard worker.
I drove an 8 wheeler tray top with a g.v.w of 26 ton Imperial and
it had a 500 Holley on it. The reliabilty was 1st class and a credit
to Yank engineering... All the best from Skyeking......
It sounded to me, when he opened the carbs up all the way that it had one heck of a long flat spot before the RPM's started to come up. Watch the throttle's on the side of the carbs open, then listen too how long it takes it to raise the RPM's up.
Anyone else hearing the same thing.

Kurt, that flat spot is from the dyno loading the engine up; it loads it and the engine has to overcome it to generate the hp and torque measurements. I agree with 42K3, though: this is always an entertaining video.
