I am rebuilding a '48 M, early serial #. What parts should I use to get more hp out of it?

Make sure it has a High altitude (5000 or 8000 ft)
Put in Fire crater, or high dome pistons
Use a large bore kit
Run a 450 Camshaft, intake, and manifold.
While you are at it why not put on a front set of gears and cover to convert it to live hydro. JimN

High altitude? what do you mean?
Are the rebuild kits here good? steped up piston kits? or are there others that are better?
The 450 cam and intake manifold a direct fit? and what size carb should I use then?
Help here is greatly appreciated.

The high altitude parts were used (stock) on IH/farmall tractors to compensate for use at 5000 ft above sea level, and 8000' above sea level. The compression was raised (I believe) with smaller combustion chambers, and pistons with domes/humps sticking up higher than the block. Todays regular unleaded fuel has enough octaine to prevent the higher compression from spark knocking even at sea level. Propane cylinder heads (from factory propane tractors) are also high compression. Cylinder head combustion chamber volume for one cylinder (and volume of piston hump subtracted if it has them) is placed on the right side of a math ratio with the volume of one cylinder on the left. For example if a chamber had a 60cc volume, and the cylinder (displaced volume was 500cc (bore area times stroke)) the ratio would be 500:60 or 8.3333:1.
The kits from here are well liked. The carb from a 450 is needed. All mentioned parts are bolt on replacement. Good luck, JimN
