As I was wrenching on the C3 in my driveway a couple of months ago an older gentleman and his wife, on a bike ride, stopped to chat. He told me that I had his dream car. We chatted about the car and I showed him around. We later swapped business cards and soon he was on his way.

Every now and then he would reach out to me with a link to a potential purchase he was considering. Finally, he put an option on a 1970.

Tomorrow after work, I will be going over to see it with him.

If I only knew then what I know now about C3s !!!

Stay tuned.
 
He was the guy we were chatting about... but he reeeeeeally wants blue on blue.
 
If the Engine is original it will be factory high compression in the 1970 Corvette.
They do not like USA Pump gas 93 or Euro 100 octane that is actually 91-93 RM/2 USA rated gas.
It will detonate on todays gas unless timing is pulled back 10-15 degrees BTDC.
Will try and overheat then cruising.

They do like straight uncut pure 100LL USA Aviation gasoline & 110 Motor octane straight uncut Race Sunoco or VP Race gasoline.

All 1970 & earlier Pontiac GTO & Firebird, Grand Prix & 2+2 Cats the same way.
4-bbl & Tripower.

Only Engine I have found from the muscle era than runs reliable on 87-93 octane gas is an Olds 425 V8.
Others have reported same as me.
 
1970 is the last year of factory high compression.
GM.
Mopar Dodge used High compression till end of 1971.
