66 L72 Biscayne in SuperStock

Years ago, I used to help a local racer, who ran 65 Big Chevs in Super Stock. This was in the early-mid 70s, his 65 Biscayne ran SS/KA with a 396/325, he later swapped the running gear into a 65 Impala wagon, which ran SS/LA, I think it was. I remember he ran a Turbo 400, which unless I am mistaken, was the first year for a 3 speed in a Chevy? Back in those days, S/S cars had to retain stock style rear suspension, and those cars had a habit of ripping the upper control arm brackets out, even the BB cars, that had 2 uppers.

I hadnt thought of the upper control arm issue.

I have seen examples documented of the big Chev in SS/Auto, not so much impact loading, but it seems indeed the loading was too much to launch a winning stick car.

There was a T400 L72 for its final year 1969 only but it looks like very few were built like under 100. I dont see any of those in the win sheets either for 1969-71 but as I pointed out I'm missing a few event results from those years.

Do you have a link to Dwight's site you referred to?

http://www.classracerinfo.com/ There's a sticky on the S/SS home page.

Surprised no one mentioned Richard Feldman. He had a 66 , bought new, I believe.
Raced in stock but was pushed into SS in 1972.

Lots of issues with running one of those cars in the late 60's
Long wheelbase but they would hook hard still..right before they would rip the upper cross member off, or tear the end off an upper trailing arm..If none of the above first, they'd knock the left lower trailing arm bracket off the frame ...This was all with a 283 !
A spool and good axles weren't commonly available in the late 60's either.

Don't forget they overlapped the big block Chevelle and were only one year away from the BBC Camaro and two from the newer Chevy II
Case closed ..Not a big market for a SS full size Chevy.

Also surprised no one mentioned Dwight Cox. Although not an L72, one of the hardest running SS Impalas ever;.

Good morning to all,
Please correct me if I'm wrong but didn't Dennis Oliver ( Dean's Dad ) run a stick shift Impala body and Cal Method have a couple of successful Impala bodied race cars?

I cant find Dennis Oliver in the 1960-71 race year database I have.

But yes Cal Method shows up, 66 Impala hardtop, P/S=16.00 class 283/220hp. Class records Sep 1970, won class at Pomona Feb 1971.
That would be a 3-link 10-bolt rear, right? Even weaker than the 4-link 12-bolt L72 cars. Sounds like GM engineering wasn't thinking SuperStock with these cars. Still, fair enough as they are pretty light compared to today's heavy iron. I'm sure a new Camaro weighs more than the 66 Biscayne-Impala.

It was more than likely a 12 bolt. You could order a "heavy-duty" axle package in almost any Chevy. I'll probably be corrected by someone but I seem to remember that in 1967 a "posi" for your 10 bolt would cost you sixty sum odd dollars and the H-D axle assy. was just seven more.

Dennis raced from 1974 to just recently.

This thread started as a talk about SS and now has morphed into including Stock eliminator. In that case, you have to include Kevin Fogerty (1966 Impala 283-220 P/S) and Marlon Stubbs (1966 Biscayne 427-425 B/S).

Do you know what years he ran? In Stock or SuperStock? 4-speed?

I've only been collecting & analyzing results 1960-1971 race years as you might recall. Still missing some results sheets from 1970-71 as listed in the thread so it could be there.

I thought about doing the 1970s, since my 1st run at Milan was 1975, but the HP factors must be all over the place with the 1972-up "net" ratings.

I tore the end off the upper control arm in my 65 Bel Air 4 door sedan - with a 230 ci 6 cylinder.
