Think is i get a performance cam for rpms around 3000 to 4500 then get a 30 degree advance timing key cause they say it make it rev quicker and  rev kit and valve springs ya think that will make a good reliable engine the sounds good o and im adding a tach  and gonna tweak the governor so itll rev bout 4200  they say you can get away with that stock.

Well you can run these but anything with cam work is going to generate a good bit of heat to those heads. Another thing you can do is but an adjustable cam in and so you can dial it in yourself and get an adjustable billet flywheel. The heavier mass of the flywheel will help with the top end and help keep your rpms up and is also for safety as the stock flywheel may not like all that. You will defiantly need the heavier springs with the cam so it wont flutter when you crack it open. With this set up you should be able to turn a little more than 4200 rpms. Depending on how much of a lift and duration the cam is you may need a bigger start for it because your gonna have quite a bit of compression now. Id also look into porting and polish or your gonna loose a lot of airflow because of the stock restrictions. Wouldn't hurt to look into head work either.

Thanks,   You know of any better place to get cams i can go with copper head gaskets but i not wanting to dump alot into this thing $250 max basically i can port and polish my self  some but im looking for and engine the can plow during my plow days but got a nice sound behind it while idling and quick reeving so valve springs are a must  the timing key not really wanting to put a flywheel on it i have a spare also off that engine

You can send your cam out to any of the premier cam grinders (Lakota racing, vogel, Nichols performance). If your wanting to use this for plow days as well then I would strongly recommend keeping the performance parts low. Either that or find yourself another motor so you have one that's built for pulling and one for plow day and daily chores. I would stick with the governor being zip tied open, port and polish and maybe the valve springs. You don't want to put too much performance, remember you have a stock crank in it. If you want to go mod heavy then its wise to look into a billet crank so it don't break in half and all that money go to a boat anchor.

Its not only the rod I would be concerned about. The cranks are only built withstand so many rpms before they go. You could even let the person doing your cam know to do a mild cam grind on it. Too big of a lift and youll need a bigger starter. But for what your going for id stick with what you want to do.
