Joe, my 70 SS 396 nova had hood insulation. The deuce didn't. I got caught in a 1-2 inch snow with mine the one and only time it ever saw snow. I was the most useless car in the snow I've ever been in. Step on it and you spun, let off, and the rear end locked up. All you could do is kick the clutch, and steer.
On the insurance, I even told my agent it said Yenko on it. He looked through his book, and couldn't find it, so a 300hp 350, non SS it was. Don was right on the ad where it said "easy to insure".
