For the money you will spend to build and maintain that 327 ,including all the broken parts from 7k hole shots and the like you could build a 454 smallblock with the 327 valve cover stickers and have a winner !

You will be then known as the guy who has the kick butt 327 under the hood!

If you do build the 327 have fun and keep us posted with how that goes...I am sure everyone here will be more than glad to help with thier exsperiance and help you put together a screamer.......they are just letting you know things wear and break often at those numbers you are looking at and its not cheap to do either.

Basically to sum it up ...thats not the most economicall way to get that hp, nor is it the most reliable.

Have fun in whatever you decide to do !
