Any 10 second "All Throttle" 318's in door cars ?

A 318 is just a de-bored 340, very easy to make 500 hp using stock internals with 340 cast heads .550 lift 250 @ .050.
I would challenge the "very easy" part because if it was very easy only needing a set of 340 heads and cam, you'd see a ton of 500 hp 318's out there. There was thread out there a while back about 500 hp 318's and I don't think any came forward on all throttle.
