john deere 60lp

(quoted from post at 08:53:36 10/19/10)
You would barely find the difference between stock and 125 over on a dyno. Sit down and figure the HP per cu" and the amount of cu" a 125 thou overbore provides.
Get a power-bloc, do some head work and install a Berry's cam.
Then again why is more power than stock required? A factory stock 60 will handle 6500lb on a clay track in 2nd gear.
There are three things to work on first before souping the engine. They are traction, traction and traction.

I will agree that the extra power from the overbore will be hardly measaureable.

You are going to have to have a joke of a sled for a STOCK 60 to pull 2nd gear in 6500. I have seen a 60HP late A (same gearing as the 60) killed dead in its tracks by a good sled and good track at [u:01bb784b70][b:01bb784b70]5500lbs.[/b:01bb784b70][/u:01bb784b70], in 2nd gear. With a 7 foot long chain, it may hack it though.

Even on itty bitty 13.6x38 tires a stock 60 will not run 6500 in 2nd gear on a good track with a respectable sled.

The A I was talking about was on uncut 16.9x34's with a 18" high drawbar. Put the little tires on, ADD 1000lbs to get to 6500, take away 33%HP to get to stock, A STOCK 60 isnt going to run 6500 in 2nd gear!
