2011 Camaro SS Vs 1969 Camaro Zl1 STOCK

[kickasswelch69]

OK. Ive been wondering how both of these camaros would fare against each other. The 1969 Camaro ZL1 puts out 550 horses stock. The 2011 puts out 426.

Me, i think a stock ZL1 would trump a 2011 Camaro anyday of the week...

if the zl1 has stock tires the SS would probably beat it by a tenth or so based on the results I have seen. With slicks on the zl1, the SS is toast.

that ZL1 with sae net ratings is 375hp. sae gross is 430.

with headers, aggressive timing, and non-emission compliance its a beast(550hp). do the same thing(bolt ons) to a LS3 and you get nearly the same results IMO.

Just looking at the numbers in the first post should tell you somethings not right. If it truly had 430 (let alone 550) and weighed 3300 lbs, it shouldn't be a low 13 second car. But 375, with an extra couple hundred pounds, with skinny little tires and all the other short comings of a car from back then, sure.

Well what about drag radials?
Chevrolet was hoping to get the ZL1 Camaros into the lower class in the National Hot Rod Association (NHRA) and the International Hot Rod Association (IHRA) drag racing, because they knew results at the track was results in the showroom. Chevy under rated the horsepower at 425, but both sanctioning bodies quickly saw through chevrolets facade and re-classed the ZL1 engine into the appropriate class. Word spread fast, the stock ZL1's were churning out nearly 550 horsepower on the dyno.

No, they weren't. Unless you have a very loose definition of the term 'stock' (which was fairly common back then). If you swap heads, the engine still stock. And if you pull off every accessory, the engine is still stock. If you swap the exhaust manifolds for headers (and remove the rest of the exhaust), the engine is still stock. If you retune the carb, the engine is still stock. If you remove the air filter, the engine is still stock. There were other things done too but none of it would be considered to be 'stock' today, but rather 'light mods'. If you were able to go back in time and pull a brand new 427 out of a ZL1 and ran it with the current SAE testing protocols it would have a very hard time cracking the 400 hp mark. I recall hearing that when they switched from gross to net hp ratings (which did away with a lot of the old shenanigans), those engines were making about 375 hp net and the protocols have changed a little since then, but it would still be somewhere around 375 in bone stock condition.

Are you talking about a real world race or a "spec sheet" race? My vote would not be on a real 41 year old car. Even my 79 TA is maybe 3/4 of what it used to be.

im talking about a real race.

The 2011 SS will win by default. Nobody in their right mind will race with a stock 1969 ZL1. And even if they did have a stock ZL1, after 40+ years it most certainly won't be running like it did when it was new.

[kickasswelch69]

your probably right. but what if the engine wasnt original? What about a chevy crate 427?

[assasinator]

bone stock-as delivered to a dealer untouched the 2011 SS would SMOKE a zl1.

im talking 50 state legal smog. which includes EGR, thermactor smog air pump for 69. even the deadly 429 SCJ had all of that stock.


chevrolet part numbers:
Smog pump build date 352-8
Smog pump diverter valve #29297
Smog pump pulley #3932458DA
Smog system hose #3940937 used original and mint
Smog pump hose #3909940 used original and mint
Smog check valves 5361992 x 2 restored and replated
Smog tubes are mint original used with no damage
Smog pump hose clamps are all original and dated 1/69


note the tri power with required smog pump.




note the thermactor manifolds on the exhaust manifold of this 69 nova.






legend is greater than reality for 60 muscle cars compared to today.


IMO the glory days of musclecars was long before the markV bigblock. back when as-delivered power was REAL.

425 hp 409/427 W motors, and 427 ford side oilers. 12 second cars for their day. in very heavy cars. 1962-1965.

Sortino also uncovered what was said to be a "one-of-one" dual four-barrel aluminum intake manifold for a Mark II engine from a guy in Michigan. After reviewing cylinder head flow data, Sortino decided to increase the camshaft's profile in order to take advantage of port flow capability. The legendary Junior Johnson (also a member of Super Chevy's Hall of Fame) was said to have "guesstimated" that a stock four-barrel Mk II 427 was capable of 600 horsepower. Sortino's twin, a 750 cfm AFB version with a little more camshaft, dyno'd in at 660 horsepower.





Craigg Clack, here in clarksville is a long time friend of mine. his 62-63 biscaynes have adorned the covers of hotrod and popular hotrodding. he does my machine work for my turbo stuff.

The ZL1 didn't do bad in the magazine tests back in the day. I never read the articles but the numbers posted don't look bad. Those were posted on old-school rubber.

[porcupinekiller]

Don't forget the ZL1 won't even run on todays overpriced, crap pump gas. It's pretty tough to get 104
+ octane leaded fuel at the pumps these days. Lol
The performance of todays cars is pretty impressive when you consider this overpriced crap fuel we have these days. If you ran them today stock to stock my money would be on the 2011 SS.
