WOW~!

My '66 L72 Biscayne was factored "B" stock and ran 13.0's @110 when new at Minnesota Dragways back in the day.

I don't remember ever seeing any '66 L-72 big cars running in "A". If they did fit into there, I don't think they were competetive and the owner would drop to "B" where they were. Like mentioned earlier, Billy Ilykowski's(sic) was probably the most well known one (B) in the country. I tell 'ya, those L-72 cars were absolute terrors. I've heard other stories of these cars ripping out their rear control arms also. Changing subject slightly, now I know people worship '67 435 HP Corvettes like the Shroud of Turin, but if you'd line one up in a race with a '66 427/425 HP Corvette, my money's on the '66 L-72 'Vette!

Yep, they ran in B. https://www.yenko.net/ubbthreads/imag...mlins/wink.gif

A '66 Biscayne was a natural 'A' car until the '68 season when it went to 'B', but dropped further to 'C' and then 'D' stock before finally resting at 'B' in '73. Anyway, here's what NHRA showed back in the day, and that natural class(es) each year for a '66 L72 Biscayne...

Original NHRA factor page(s) - 8.56 [stock] or 8.66 [super/stock]

1965 class breaks - AA/S [note: assuming an early '66 built car during remainder of '65 season, if not in class guide they would weigh the car @ track & divide by advertised HP to determine class]

1966 class breaks - A/S
1967 class breaks - A/S [would've added weight to reach 8.70/hp factor] or SS/C
1968 class breaks - B/S or SS/D
1969 class breaks - C/S or SS/G
1970 class breaks - D/S or SS/F
1971 class breaks - D/S or SS/F
1972 class breaks - A/S [would've added weight to 9.0/hp?] or SS/F
1973 class breaks - B/S or SS/F

Hi Rob,
So if my L72 Biscayne had headers and slicks what class would it have been in back in the 60's?
Thanks,

LOL...it would depend on the year, and whether you're talking Stock or Super/Stock.

Hey Sam: what year did NHRA start allowing you to move down a class? Seems like you were still stuck where you were at in '70, maybe??
