These times would have been awfully close to records for the stock classes these car would have run in at the time so idk what was going on but they certainly were interesting tests I believe the aluminum engine would be in b/s in 69 and the iron would be in C/S
?

Stock classes were typically balanced and blueprinted engine, headers roller rockers, cheater cams , slapped bars, 7 inch slicks et. 68 had a different weight break than 69 so some things changed this other attachment is just picked off the web but gives you an idea of rules for 68 I have the 69 rule book maybe later I'll post stock Lass rules from the book
