Had this exhaust on the car for a long time and had no objections. I

In trying to reduce some vapor lock issues, I blocked the heat crossover in the intake. Upon driving the car I now had a *terrible* resonance around 2000-ish RPM (just a guess, I have no tach). It happened at 'neighborhood' speeds and made the car so obnoxious it was practically undrivable - it had to be a 10-20 dB resonance.

I re-opened the manifold crossover and the noise was gone again.


Parts I seek: driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set 16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better. 69-73 C-body caliper brackets and/or splashields Send a PM.
