high rpm massey 444

has any one done high rpm massey 444 i am looking for REALLY HIGH RPM'S my engine is bone stock now and i am running about 3,000 rpm what do i need to run 5k :)
 
Never done a high speed tractor engine.
But have done a few different antique
pullers. In a few places you can run as
fast as you want but most have some kind
of rpm limited rules. 20% or 30% over
stock rpm. Or Everyone just 3000 rpm. You
are 5.50 stroke stock. But you just have 3
main bearings. Not 5. So at least a billet
counterweight crank. With billet main
caps. Plus a steel balanced flywheel.
There are some good competitive 444's. But
I imagine they are more than double 270
cu. I think 600 cu at 2400 would pull
better and be more competive than a 5000
rpm. 270 cu. Surely 99% of pullers aren't
wrong.Sorry Vic
 
Quit while your ahead and on the green side of the grass.

Why do you want to turn so many rpms? What kind of class are you running?
 
High speed engines are typically short stroke, large bore. Just look at the dimensions of car/bike engines. Old tractor engines are not that. Long
stroke/high torque slow speed. I?m surprised you would even be able to get a 444 to 3000 with mostly stock parts. To make high rpms, you need light
parts. Not heavy old cast tractor parts.

And this is not even mentioning the cast flywheel. High rpms and cast is a bomb waiting to go off. And probably not that long.

If you want power out of a MH, Goldberg Performance knows how to do it.
 
I remember a deere G flywheel that went all the way down the track and across the road at Campbell county fair in Va. some years back . just lucky it went straight down the track about 400 ft.
 
Why would you turn a stock motor that hard? At the end of your hook it would be at like 1800
anyway. May be expensive 30 seconds sometime soon!!
