Even had the same cylinder firing order as the 302HO/351W. And of course all the much heralded "advantages" of having more head bolts and the like that were crowed about by the SBC crowd just sort of disappeared....
Oh Ford...
Cadillac actually used that firing order before Ford....1963 390 & 1964-1967 429 along with the later 368, 425, 472, & 500 engines.
I kinda agree on the cylinder heads....Valve layout is the same but reversed, Though Cadillac used the same valve layout as the LS on the 368/425/472/500 engines along with 4 head bolts per cylinder.
If anything, It seems GM had these design attributes in their engineering toolbox already....Then sprinkled some modern Valve Angles & Port designs in for better efficiency.
It's always been my opinion that the extra head bolts on small block Chevies was more detrimental than just running 4 per cylinder, Anybody that's been around 400 blocks can attest to that.
Thanks for the Cadillac history, wasn't aware of that stuff
