Damn, I remember ALL that ***** and I had no idea I was old.
As my father used to tell me back in the 1970s - "Mark my words, gasoline will someday cost $1.00 a gallon."
Variable Valve Timing and computer controlled ignitions help keep detonation in check as well. Even todays turbo cars can have a compression ratio of 10:1 and more. You would need a little monkey under hood to turn the distributer under different loads and rev ranges back then I would think.The muscle cars of the late '60s were running compression ratios in the 10-11 range IIRC, which was high at the time, but pretty unimpressive by today's standards. I'm no expert, but I think the difference was the flow efficiency of their cylinder heads was pathetic compared to today's technology so they needed that kind of octane to avoid pre-detonation. And, since I never owned one of those cars, it may be that they ran OK on lower octane, but ran better on the higher octane.
Don't forget the all-importantThat's the reason you had your heads ported and polished, duel point ignitions, high rise intake manifolds, headers, high CFM carbs with dual pumps ...![]()
extended shackels on the rear leaf springs and over sized tires! those would add at least 50 hp!I used to have a 57 Chevy 2 door hardtop with all of those!Don't forget the all-importantextended shackels on the rear leaf springs and over sized tires! those would add at least 50 hp!
To the latest generation this probable sounds similar to what I hear when my granddaughter orders a cup of coffee at Starbucks!!I used to have a 57 Chevy 2 door hardtop with all of those!
And Gabriel Highjacker air shocks, Muncie 4 speed, Hurst 'mystery' shifter, and Hush Thrush cans hooked up to my Hooker headers with a Crane Fireball cam add for good measure not to mention Accel Oil coil on the firewall with Accel dual point distributor, Edelbrock highrise and a Holley 650 CFM dual pumper!![]()
WoW you must have ruled the strip and drive in! I am jealous!I used to have a 57 Chevy 2 door hardtop with all of those!

And with all that you probably still were not able to run more than somewhere around mid thirties total degrees of ignition timing advance at best.That's the reason you had your heads ported and polished, duel point ignitions, high rise intake manifolds, headers, high CFM carbs with dual pumps ...
Because of the above modern technology sedate passenger sedans now run with ignition timing advance in to the fifties using methods that control combustion and pre-ignition that were just not possible back then.Variable Valve Timing and computer controlled ignitions help keep detonation in check as well.

Well, she was still pretty quick ...And with all that you would probably still were not be able to run more than somewhere around mid thirties total degrees of ignition timing advance at best.

They sure were. I wish I had been smart enough to keep some of them. I wasn't disparaging those old cars as much I was musing about realizing as much of their potential as what is possible now.Well, she was still pretty quick ...![]()
I had a friend with a 55 Chevy he had built - it would actually do wheelies if he kicked it hard!They sure were. I wish I had been smart enough to keep some of them. I wasn't disparaging those old cars as much I was musing about realizing as much of their potential as what is possible now.
I used to build and run high performance cars, things like 426 Hemi, 440 Six-Pack, 429 Cobra, Pontiac 455 HD, etc., mostly big block muscle era cars. If it was possible back then to realize anywhere near as close to the level of combustion efficiency that is achieved now it would have resulted in staggering levels of power produced from those big blocks. As inefficient as those engines were they still produced so much power that getting traction was always a major struggle with every build.
