Authentic 318 Poly Four-Barrel Conversion - 1958 Plymouth

Thanks, Viper Guy Posted 2016-09-07 9:08 AM (#520699 - in reply to #520645) Subject: Re: Authentic 318 Poly Four-Barrel Conversion - 1958 Plymouth Expert Posts: 2007 Location: Branson, MO Should work. I believe there is adequate linkage adjustment available for proper connections.

If you just pull the rod forward to reach the lever, most of your throttle travel will be used up and you won't be able to attain WOT.
