While I understand your intention for "official" verification, I would think the opposite strategy would be most beneficial. Start with Class Racer Info, then go to NHRA data to verify. You will find access to the information you need so much quicker and easier to understand from CRI than NHRA has the capability to provide. Plus, if you are doing research there is relevant data available on CRI that simply is not available anywhere without doing calculations and time spent on other sources. By the time you wade through all the obscure data on the NHRA website just to find where all the information is, you can already have your decision made by using CRI.

The '71 302 2bbl is rated at 162 for stock eliminator. Not as good as some of the later 302 2bbl engines, but not unreasonable.

The 351/240 Windsor and Cleveland 2bbl engines are probably not good choices.

The 351/285 Cleveland 4bbl engine is a proven competitor, though expensive to build.

The 429 would also be very expensive to build, though can be competitive.

The 351/280 engine you reference is a Mustang-Cougar engine only.
