Like with the Olds 403 motor.
That nice big bore motor that could’ve made terrific use of big valve sizes, yet the heads suck!
You can’t really knock the Pontiac motor because it was very very well conceived!
Since it’s introduction in 55 at 287 cid it was able to be stretched 59% up to 455 cid with no major external redesign!
I know of no other passenger car motor that can lay claim to that !

I agree. I still question the 3.25" mains they felt were necessary on the 421. I've read the reasoning but eh? Take that out of the equation and sheesh what a great set of additional options arise.
