I am new to engines, and I want to build an engine, to put in an old mustang so I can go to our local track next summer. I have been looking on ebay at 302 blocks, is that a good place to start? I have an engine stand, i just need a block, or a place to start. How much will it cost to build an engine, I see alot of people bore the 302's .030 over. How much does something like that cost. Any help or advice on where to start i would really appreciate, thanks, kevin
