rule book states that you have to run the same year block or use an "approved' block. kinda depends on how close you follow the rules.

Nowhere does it say this!

Must be same year and make as car used, aftermarket NHRA- accepted cylinder blocks permitted. section 10a page 3 in the stock section.

The 71 & 72 302's have the same block, heads, cam, and intake.
The numbers on the carbs are different.

Engine must be same year and make as car used. That means it has to have all the specs listed by NHRA for the year / make and model claimed. You can put a 1984 Ford 302 block in the '71 Maverick as long as it meets the bore / stroke specifications.

Note there is a comma separating the two thoughts.

Aftermarket NHRA accepted cylinder blocks permitted. That means if a Dart, World Products, etc., block is what you want to use it is OK only if approved by NHRA.

Use some common sense. Why would NHRA want a '71 (only) OEM block in your '71 Maverick? And then also allow an aftermarket non-OEM block?
Some factory production blocks have no external markings on them indicating what year the block was manufactured. It doesn't make sense.

It is quite interesting how experienced racers can read the bible and walk away with completely different and opposing ideas of what was printed. Just shows how vague the rule book really is.

Shout out to PartsBob, see ya in Vegas next weekend ??

The rule book could be written for every possible issue, it would be 10" thick and still it wouldn't be read or understood by many. Case in point, Obamacare is 2000+ pages and those that wrote it and those that must follow it one year after still haven't figured it out.

If NHRA wanted you to have a 1971 casting 302 block, and nothing else, it would be clearly stated. The engine blueprint guide, the class guide & the rule book are a threesome that are used together. You can't just use one of the three and hope to accomplish something.
