does anybody know of any till tricks to get a lil extra zip out of a 4 cyl flat head continental motor?? Never seen a VC puller before.

At our pulls we pull a VAC in 3500 stock class, it's 3 7/16" overbore and some minor cam work and a magneto, it beats everybody. I have a VC behind the barn and am contemplating stuffing a bored out F160 in there. Tractor has the stock F124 in it now but it's locked up.

Do you have any idea how much HP the Y69 has?

The Y69 only has 69 cu.in. This engine was used in the Massey Harris Pony and rated at 10.33 horsepower, while the VC with the F142 was tested at Nebraska at 23.75 horsepower.

P.S. I once owned a VI that had a Y91 engine, complete with the IH power unit sheet metal. I swapped the front axle. rear wheels and some other parts for my V, then sold the remainder at auction. The installation in that tractor was poorly done and and had many leaks, but the engine did run good... Gene

I have a VC. You state yours has a y69 engine while the original engine was a F124 engine.

I have a VC that was originally a F124 and I have bored it out to 162 + .o3o" to give 166 Cu.In. I have not made any other changes to it. It dyno's at 30 horsepower. Pulls strong on 12.4x32 tires, but is a little bit light and spins out without working the engine. I have 1 set of weights to put on it before next year.

The engine has plenty compression and a little work on the cam and opening up the valves to breathe better could probably result in horsepower in the upper 30 range. I run the stock battery ignition. Still running 6 volt system.

I pulled it in our local pull and was beat by 2 C and 1 Super C Farmalls that were running weights. Our pull is strictly by plow class and not by weight and the Farmalls are a heavier tractor and pulling on 34 inch tires.

It is a really fun tractor to play with.
