That's what I was getting at. The really fast guys have to be doing something with suspensions, even if they look stock. Things like different spring rate (front and rear), loose bushings up front and maybe shocks with different characteristics than OEM assembly line stuff, etc, etc. I can't believe that everyone of these cars is running on exact assembly line spec stuff, even if it appears stock.

Plus, tq converter design must be completely different from a slick car, so as not to hit the tires too hard. I would wager the guys running 10s aren't using some out of the box TCI deal from Jegs.

I dig the stock appearing cars getting it. Kind of what I have in mind for my ‘70 Monte Carlo.

The fact that he runs 131mph with 2.5" exhaust is very interesting considering how many think they need 3" with 4-500hp engines.

What great "sleepers" all those stock appearing cars are..

Does make you question the need for 3" exhaust.

I would guess this car has been lightened significantly. I can think of a number of ways to pull weight out : sound deadener, seat frames, gutted electronics (not that these cars had a lot of electronics), door bracing.

Acid dipping, thinner repro parts, alum stock appearing radiator (painted black), small light battery inside gutted stock case, etc.

Re: L89 Stock Appearing Nova [email protected]

Don't get this car confused with something you see driving down the Katy Freeway.

It's a race car, built to meet the specifications of a distinct class and optimize the perameters of the competition it will be involved in, that being 1/4 mile drag racing.

'67 Chevelle Malibu, Catalina Blue, 540 inch Rat, Air Flow Reasearch 290 CNC Heads heads, Custom Hyd Roller, .675 lift, 234, 244 at .050, Lemons Headers, Holley Multiport Fuel Injection, TCI 6X 6Speed Automatic, 12 bolt Posi Eaton TruTrac, 3:31 Richmond Gears, front and rear power disc brakes, Global West Suspension, etc.

Re: L89 Stock Appearing Nova [email protected]

is this car really turning a 1.50 short time on true bias ply tire , or are they a super soft radial made to look like a bias ply, the bias ply from the 60 and early 70s was hard as a rock. i bet if you took one of those tires the nova is running and analyzed it u would find it a cheater tire

In regards to the Nova, his short time was 1.66 on the 10.63 run and the tires are NOT CHEATERS,they are Goodyear Polyglas repro bia plys.
So you would lose that bet
..did you read our rules on the Supercar website? NO STICKY OR SOFT COMPOUND TIRES.PERIOD

Heck,I have raced on the IDENTICAL Goodyear repro bias ply tires (G70-14) and my best 60 ft. was 1.89

Thank you for the kind words (along with reading our rules) and yes-they are a true bias ply tire:

They drive like crap and I can light them up at highway speeds up to 55 MPH by just rolling the throttle. Lots of fun
Ted's Nova runs the same tires.

All you have to do is stick your fingernails into a set of these new reproduction tires. 60's tires (even 60's era slicks) were as hard as rocks. These new tires are made of lots softer and stickier rubber. If you haven't tried them, don't knock them.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

BIGOT is a word used by people that can't use logical reasoning to prove that you are wrong when you don't agree with them.
