I changed out the 2.75 ring & pinion for a 3.50 & now have a small annoying exhaust resonation/vibration from about 1700-1900 RPM's. I can live with it but it's annoying the wifey (no I don't want to get rid of her!!). Any ideas? Exhaust system & car as follows;
1936 Plymouth sedan fully insulated & full interior.
SBC 350 w/Rams Horn manifolds, 2.5 inch pipes, "H" crossover & 50 Series Flowmasters w/SS megs for tips. Also, system sounds very good & I'd hate to loose that. Thanks.
