That being said, for the most accurate info, you would need the blueprint specs from the actual years you are researching. It seems some things have changed through the years in the NHRA Classification Guides, so what is published now, may not be what was originally published in 1962, 1963, etc.

Thanks I did look in there but just copied in the excerpts above that gave valve LIFT.

For the 361/305hp the NHRA Blueprint .doc files say
1960=M lift .446 .458
1961=H or M lift .430 .430 or .446 .458
1962=H lift .444 .456

Note that 1962 says "H", but the "H" cam was always either .390 .390 lift or .430 .430 lift. That .444-.446 intake .456-.458 exhaust lift is almost always an "M" cam everywhere else it's listed. I'd bet all the factory cars were "H" cam but was wondering, was there an "M" cam option for 1962 with one of those "special letters to NHRA" that all of them wrote now & then.

Seems the National Winners/Records 361/305 cars were ALL 1962 so I'm trying to figure why, other than lower head cc, that year was so "hot".
