I'm sure hundreds of people have.

We built a 455 - 25 years ago. ported 670 heads. 20 cc dish piston. zero decked.
235 / 245 @ .050 - 110 LSA cam. Ran pump gas for many years until upgrading the shortblock to E-heads.
We didn't think it was any big deal, not sure why some do?

Jim Hand ran 11.4 in a more than 4000 lbs car with iron d-ports and flat tappet. A class by himself. Going 11.7 at 3700 lbs is not the same, hundreds if not thousands have done this. 99% don't post here.

I'm impressed with a person running 11 to 1 compression with cast iron heads on pump gas with a mild cam. I've seen it claimed but how legit?
