Driveability of high compression cars

**Dave Rifkin** · #1 11-15-2005, 10:13 PM

I am contemplating the purchase of a 1970 Z28 and was wondering how you guys deal with the need for high octane fuel for these cars? Do you install thicker head gaskets to reduce compression ratio or are there other tricks to make these types of cars more driveable with today's available fuels?

How much are you going to drive it?

We buy leaded fuel from a guy in CT.

I would hope to be able to drive it on weekends and other nice days.

Can you buy high octane fuel in your area?

I drive my Z with 10.5 to 1 and have no trouble at all. I mix some of that Jack Podells true lead octane booster with 93 octane. Buy it by the case. Works great. You can get up to 103 octane. Its called: Max Lead 2000. Aviation fuel is iffy in my opinion. JMO

Call Charley, he probably can get you a discount since he will now be buying Jet A........

That's a helpful suggestion. I would have to go to the local dragstrip to get high octane fuel for the car. The lead additive is a more practical solution in my opinion.

Works good and is reasonable. You can run CAM 2 or VP but not necessary. Jack Podell (574)232-6430.

I just filled my car up for the winter, we have Turbo Blue 110 Octane leaded at the pump, my car just loves it. Just about passed out when I saw the price it went to recently $5.19 a gallon, so I guess if you don't mind the price drive away!!
