I have an oliver super 77 that i plan on pulling... does anyone know how i can get more power out of it without adding a turbo? [/quote]

Really not a whole lot you can do that will give you a
noticeable difference until you dig in a do a lot of machine
work. Have to check the rules on where you are pulling first

go to 3.75 pistons with a .5 inch dome , a 770 with
880 valves head , a new 1550 manifold . a larger
carb . and I just got you to 72 hp . that's what it
takes

If I had a 77 I would use it for farm work. There was not a better tractor made in that era

WOW..4.125 bore x 5.125 stroke big intake and 4020 valves 117 hp..maybe i should have gone the cheaper route and pulled farm stock. P.S.@ stock rpm

Many things can be done but they all cost a good bit of $$ Boring it out increasing the compression etc etc. When I say boring it out I mean as in bigger sleeves and pistons etc

Why ruin a perfectly designed tractor? Oh well, it IS yours, so none of my business what you do with it. I personally like to keep them as original as possible and use them for what they were designed to do.
