I have a buddy of mine that is a Mopar man, has a 69 Charger, hemi, etc. etc....
Got to thinking, would a hemispherical head for the Y ever be possible (I guess something like the Boss 302 head)? How much would the rocker shafts/arms get in teh way of just such and endeavor? And would there be any great benefit?
Just musing...
