55.2-59 gas pedal height

I'm with mr48, leegreen and nvrdone on this one. put the seat in or use something of the same height for mock up (the seat is best because you get the correct feel), then sit in there and ensure the pedal is at a good angle for driving. the distance to the firewall is sorta irrelevant as long as you can acjieve full throttle before bottomoing out the pedal on the floor, firewall, floor mat etc. once done this then build a pedal stopper so, like nvrdone says, the linkage and carb throttle shaft lever dont take the full hit of the mechanical advantage given by the set up. if you had a cable operated linkage this would be a very important step. when all done ensure you install a return spring that will do the job but not overdo the job. otherwise your leg will pay the price.
I once had a boss who would drive into the shop, announce he had a problem with his truck and i needed to drop everything in order to get his truck running perfectly. this got old after a few times of "its not running right, I dunno why, I was just driving in to work" and me finding he had floated the valves, bent pushrods etc, again. anyway, long story short, I installed a screen door return spring on his linkage. it was awhile till he came back but when he did he asked if I still had the original throttle spring. haha
I also installed a golf ball under his seat so the "funny noise going around corners" complaint was an easy (but took a long time to diagnose) fix.
