416 engine

Something must be up with it to only run 11.30’s in that weight of car at almost 13 to 1 compression
I have a 10.4 compression stock stroke 360 that runs quicker than that at a good bit more weight/(3300) with less gear and convertor, and its nothing special. Eddie heads mildy ported by a local guy and small tube headers. No where near 500 horse being made there
