Trying to decide how I want to restore my 67 Chevelle SS L-35, I have some friends telling me to tone down the motor, go down to a 3.08 for the rearend because I want it to be a driver. Stating the difference in gasoline compared to the 60's and also if I put the stock 3.55 in the rearend it will run at to high of a RPM for highway driving. My gut is telling me that I want to restore it stock except for adding front disc brake option. This car is getting a complete nut and bolt rotisserie restoration, it has 97k miles and I know it was driven like that being kept stock so my question is what would you do? I welcome all opinions and guidance. Thank you for your help in advance.
