Guys like you set the hobby back decades. Technology comes from the top down. You evidently know little about coatings and what they are for.
Stay in the 1970's. Sounds like it's where you belong. And make sure you use 1970's shocks, tires, cams, carbs, converters, clutches...the whole of it because time never moves on.
What is being done now was considered impossible just 25 years ago. That's ONE generation. If I said 25 years ago guys would be running .750 lift on street cars they would have 5150'd me and I still be in a runner room.
Sounds like YOU need to get real and open your thought process. Don't forget stud mounted rockers. That was all the **** back then. Rediculous.
