'67 400 heads on a '72 455?
Hey dudes,
I'm building up a 455 to wail on in my '67 GS400, rather than run the risk of hurting my #'s matching 400. I'm going with Keith Black hypereutectic pistons, .030 over bore, and a Comp 268H cam with 215 degrees at .050 and sub .500 lift. My question is: can I use my '67 400 heads on the '72 455 block? Would there even be any advantage? I was told the earlier heads have a slightly smaller chamber worth around half a point of compression. I'll surely be using an aftermarket intake manifold, so I'm also wondering if there's any difference there between the earlier and later heads. Eventually I'll be getting a set of Edelbrock aluminum heads, but I just can't swing it this year.
This is my first Buick build, but not my first from-scratch engine build by any means, so any Buick-specific tips, tricks, stuff to watch out for, etc... would be highly appreciated. Can anyone recommend a good engine assembly book? I have a factory Chassis Service manual, as well.
Thanks in advance, and drive fast with class,
Justin
