318 Rebuild - Upgraded Parts?

There are some things you have to have to make good power. One is a decent compression ratio and good ring seal. So replace the pistons with the KB hypers. You have to have the block machined anyway, so have them deck the block to get the pistons to the deck height. Have it internally balanced. Then, you have to have a solid set of heads. I'd scrap yours and replace with EQ Magnums. Than you can bolt on anything, run a decent cam, and make some reliable power. Not sure what he included for that price, but I know I could do something similar for $3500 or so... and it will equal any mild 340 you come accross.
