I've put over 10K miles on my aluminum Pond block 482" side-oiler built by Keith Craft and it's been rock solid. I would do it again in a heartbeat. I had the car corner weighed and it's 49% front and 51% rear with me out of the car. Its handling is very neutral.
Power??? I'm still thinking about installing a "hidden" 300Hp progressive nitrous fogger system as there's never enough horse power. Just for that pesky sport bike that's in search of a lesson... ((
