Before you spend a bunch of money building an engine and hopefully hitting the right pieces to make it work, maybe check with a company like CNC Motorsports (I'll use them cuz they're 50 miles from where I live and have good products and service) and compare costs of building the engine to buying one already balanced, clearanced, assembled, and ready to go!!!!! With the price of machine work and parts, if you don't have your mind made up on exactly what is going to work best you might actually save money!!!!!

The shop that does the machine work is probably the most important part of any engine build!!!! If the clearances, balance, cleaning, and hardware isn't right it just doesn't really matter how good the pieces are you put in it!!!!!!
