I am graduating college soon and that means graduation presents. I have a 89 5.0 with a full exhaust other than that it's stock. I have a block out of a 94 gt. Dad said he will either send me on a vacation or foot the bill to start the process of building that block (ex. Boring the block etc). My question is, is it worth throwing the money that it will cost to build the motor into a block that is so old? And if so what are the limitations of that style block?
