Cat Sixty dyno

That 60 is smoking hot, in a literal sense of the word. I never would guess that much HP out of it.

Hi, Mog5858.
WOW!!!!!!!!!!!!!!!!!!!!!. THAT is INCREDIBLE. Just a great OLD engine. Reminds me of the story from a few years back when some people tuned a Cat Sixty to factory specs and had it emissions tested - - - - - - - - and it passed.

Just my 0.02.

Wow that's great, congrats! I would think 100 is within reach!!!

thanks boys it was a pretty fun time that was for sure. i was figuring 72 HP would be good. one think is running the higher compression is that the exhaust run way cooler where it collects and it not as thirsty as one might think.

that is one nice 60 i noticed the mechanical fuel pumps instead of the vacuum tank what about the carburetor and air cleaner? that big engine has a lot of potential is there something about stationary use that says to put trans in gear and lockout steering clutches so the top shaft gets lubed? thanks for the test

What a great video. Thanks for sharing.

You mention higher compression. Is it the high altitude pistons or are the heads cut or both or???

Chad, if I remember correctly Mog told me it had John Deere D pistons in it, perhaps some other tricks were done inside that engine as well. In any case though, that's one cool Sixty.

Thanks for that Mate !! .

well Chad Toby got the most on the info right. Clyde is one of them guys that will away just get a little more out. the more i look at the old sixty i think i going to try and right a story for the magazine about it and how much of a hot rod it is. he dose lost of work on the big gas tractor. the maniacal fuel pumps help out a lot and he built a heater so as to not have the carb freezes up.
