1974 Duster
Just back from a road test.
Holy Sheep dip!
Car is just brutal on the tires now. Before from a dead stop it would just haze the tires a little bit and just take off, a nice launch from a light if you will.
Now? The tires instantly go up so hard it bangs into second and then THIRD before it starts moving and gets that lazy "I'm going to put you in the ditch in about 2 seconds" tail motion that indicates lifting would be your wisest next option. pronto.
And it sounds like a NASCAR stocker shooting out of a corner when you are wailing on it. Me likey. A lot.
I'm going to have to invest in some tires.
Only complaint about the headers is the one tube (cylinder one) near the power steering was just hitting the box. I was able to tweak it away from the box about 3/8" without damaging the coating.
