Driveability of high compression cars

[MosportGreen66]

We buy leaded fuel from a guy in CT.

I buy the highest octain pump gas and mix it with Av. gas 50/50 mix. This works well on my 427 C.I.

I run my 327 on 94 Sunoco....It has a .003 deck (cut pistons & squared the deck front to rear and side to side ) with a true 10.5 to 1 compression.No problems.....My guess is without a true blueprint most 11 to 1 motors are hardly that.I would have been lucky to get 9 to 1 on mine.

I run the Jack Podell Lead/Octane additive in my soft valve seated L-78 Chevelle for years now.Just 12 oz. to every 10 gallons of 93 seems to agree with it.
She does run hotter though.

Rick...just pump some fuel out of your Sunoco Gas pump!

just curious how some of these l78 and l72 cars are tuned. i have 36 degrees of total mechanical advance in by 2750 rpm, no vacuum advance. i nee to mix race fuel to control detonation.

my camaro has an 11.5:1 350sbc and i run a mix of either VP MS103 or VP C12 with 91 octane pump gas.i can get all the race gas i need thru our race team and the price is right "FREE".ahh the smell of race gas coming from the exhaust of a healthy sounding street car
