Take a look at the folks that run R/SA and U/SA in NHRA/IHRA Stock Eliminator. These folks know how to legally cheat and all the tricks to run fast. I met a gentleman in Englishtown who was running a '65 Dodge 9 passenger station station wagon, 272/2bbl who held 7 seven national records. Gettin' it done @14.20 seconds. The big difference in camshaft specs. (because the lift limit is 4.50"). So the custom ground cams have some wicked duration that won't let them idle at less than 2500rpm. But it canbe done so do your r&d well and don't give up
