Are there any books or other media about building, switching, tricking, hot rodding, parts swapping, casting numbers etc? I have had little luck using internet search.

(quoted from post at 06:02:53 05/12/15) Not that Im aware of What do you want to do?


First off I like to learn everything I can about things that interest me.

Second, I am slowly getting ready to do a rebuild on a 77. This will be a working tractor. I want to get he best bang for my buck. I do understand I cannot make a 90 hp tractor out of a 77 nor do I want to.

I have read here that 3-3/4 sleeve kits are possible but I find none when looking at kits. I have a 770 head and various parts. Will it help me add a little? These engines are designed to run on lower octane fuel. Would bumping the compression up to 8 or 8.5 - 1 utilize 87 oct fuel better?

This will be a working tractor hobby farming 15 acres along side a 460 Farmall. As long as I am spending money I want it as solid and powerful as is reasonable. I understand that just freshening up a tired ole engine will do wonders but it is my nature to push limits a little. I am not looking for a puller or something just slapped together that runs for parades.

I am a fair mechanic and have rebuilt a few car and truck engines in my time. I never realized there was more that could be done to my favorite tractor beyond a set of M&W pistons so I never pursued anything beyond fixing what broke on our couple Olivers.

Any help and guidance is much appreciated.

Well depending on what size pistons you have already a simple 770 carb on a good running engine will net you 55+ horse at stock rpm's. If you have a head guy with a bowl cutter I would suggest bigger valves. The easiest of which is to
find some late 550 valves that are larger than the 77-770. If you go to 3 3 3/4" pistons and a bigger carb you are looking at 60+ horse. But if you are going to work it alot I have heard that the 3 3/4" pistons put more stress on the
main bearings. I had a 77 that I pulled with and attended tractor rides that had 3 3/4" pistons and .100 of the head with stock valves. I didnt have many hours on it but it was fine and always had plenty of power in the stock classes
at a pull. hit up external_link.com for your engine needs. You can also look at murphys motor service for some extra goodies such as aluminum roller rockers and recast intake manifold. 77 and 88's are one of the easiest motors to get
power out of without machining.
 
I would suggest having your cam reground with a stock RPM puller grind. This will help increase the "breathing" of the engine
without machine work. In addition, this will make your engine run more efficiently while working it. Do not forget to have the
lifters re-surfaced for maximum longevity.

Thanks, I was wondering about that. I know cam design has come a long way since 1950.

(quoted from post at 12:02:53 05/14/15) I think you need to change what you are smoking!Late 770 tractors would do 50 but not 60 on an accurate dynometer.

What are you talking about?
