Regular or Super

Hi, I'll be picking up my vette for the first time tomorrow, what do you guys put in your tanks, its a 75 L82 and apart from a holley carb and stainless exhaust i reckon its pretty standard. I know standard US fuel has a lower octane than ours so this would suggest standard 95, however I always put super in myS5 and i swear it runs cleaner and nicer.

Regular - its a smog era car and low compression (higher comp than L48 but still relatively low) - unless someone has upgraded with aftermarket heads etc
