How long did you own it and where did you race at?

I had it from '68 - '70, it developed a nasty habit of ripping the trailing arms off the bottom of the car which would then cause the trans cross member to tear off the frame. I'd go for the shifter and it would barely be sticking out of the console!
I raced it at Islip and West Hampton, and Connecting Hwy, 150th St & the Conduit and about 100 different lights throughout Nassau County!

Norm Fryer's 007. Bill Izkowski and a local home town favorite was The Pied Piper (Valerio Bros.) with help from Grump, also ran in B/Stick. I think the 427 Fairlanes and Mopars ran in A/Stock back then. Slicks, headers, air bags gauges a Hurst Competition Plus shifter and a super tune (balanced, clearanced with some head, carb and distributor work was about all you did or needed back then. Don't forget the Cragars!

I've posted these before but ... a buddy owned this L72 4spd coupe back in 84/85 , N50's , glass bumpers , headers and tunnel ram iirc it ran high 12's . It's back in the US now being restored.

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!

[Verne_Frantz]

Yep, they ran in B.

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?
