A 1,150 horse power chevelle??!?

"BTW: The LS6 is only rated at 405 HP"


That's the wrong LS6. The Chevelle came with the big block 454 LS6, factory rated at 450hp.

Do a google search for chevelle and ls6 to see some examples

You have that backwards. Avgas is LESS volatile than regular gas, so it evaporates SLOWER. Try it sometime, and you'll see. That's why it's hard to start race cars in cold weather....the gas is harder to ignite.

i've seen it happen. pulled straight from the fuel tank of a cessna.

AvGas does burn slower than regular gas, that's why it has higher octane.

Octane = the slower it burns the higher the octane.

A good link that expains the history of auto fuel and JET fuel.

I concide 1970 Chevelle LS6 😉

Perhaps I should clarify my earlier statement: Chevy never offered a Chevelle RATED at more than 450hp. That was the LS6 454.
There was an LS7 454 that had more compression and a hotter cam, but was over the counter only.

The LS6 was truly around 500 hp. 11-1 compression with a solid lifter cam. They thumped.

The ZL1 427 was around 550 hp, but rated at less. I've seen 600hp estimates, too, but I seriously doubt that engine had 600 hp. 550 is more like it.

Really, the ZL1 was basically an aluminum version of the L88, with a bit different cam.

And yes, once again, Avgas, or high octane racing gas, burns SLOWER, and IS HARDER TO IGNITE. It is less volatile than regular auto gas.
And whoever said they saw gas taken from a Cessna and let evaporate, I'll bet you didn't see it side by side with some regular unleaded, although I fail to see how evaporation rate has anything to do with volatility. Alcohol burns MUCH more slowly than gas, yet it evaporates instantly.

and i've spilled enough 87 octane putting gas in the mower that i know this stuff went faster

Ok, you got me on the technicality, but the fact remains that Avgas or high octane race gas burns slower and is harder to ignite than regular unleaded car fuel, which is what we were referring to, regardless of whether we were using the word "volatile" correctly.
And I still don't believe Avgas is more volatile than regular, even by the correct definition.

i dunno, usually when i spill regular quite a bit of it reaches the ground. this stuff... not a drop hit the ground
