BBC horsepower help .
Guys, I've got a chance to buy a 454 with a 30 over bore and oval port heads . The motor was machined several years ago and never run , it has been sealed and stored in a climate controlled building until about a year ago and is not sitting in the owners personal garage . The motor has stock crank , new unknown flat top pistons and I'm assuming stock rods .
Now I'm not a motor person so can you guys tell what it would take to make this a 600-650hp motor . Just in case anyone is wondering I can buy this motor for $1200 . Thanks
