Breaking Point On A 440 Block

I wouldn't worry about it until I'd raced the thing.

I'm a performance motoring journalist so I see alot of build-ups and talk to alot of guys personally about there cars and the biggest issue I see is guys get sidetracked by what they're planning down the road before they've even finished doing what they're doing right now.

Finish what you're doing, race it, enjoy it and then think about the next step so you're ready for if/when it breaks.

Cool car dude, get it on the track.
