Vintage Motor's data/info

I don't understand the question. Those are some fuzzy *** photos
No question, but I found the fact that they listed the Hyperpak 170 for 2 years & the 225 for 1, even tho' the 225 was a DIY/Dealer-install only deal. The installed ht of the valve springs is also listed shorter on the 4bbl, ??, first I've heard that one. Yeah, the lens on this phone ain't the best, & any farther away would make it too tiny. It's plenty readable when I zoom it in the gallery, 'til I get a new PC & am able to scan again, that's what I got. Also found the Al-U-minimum block O/S lifter specs interesting....
