I have a 1968 Plymouth Fury with a completely totaled out back half that I've decided to pull the drive train from. I'm installing a freshly rebuilt 727 with a reverse manual valve body and 383 that has only 35k on it into my 1992 Dodge Pickup 2wd. I'm also installing the Hughes Whiplash cam. My concern is that on the Hughes website it states that the cam should be installed with big blocks with 8.5 to 1 compression or lower. From what I've read my 68 Plymouth Fury Commando 2 barrel would have came with 9.2 compression. Other upgrades I plan on running is a factory 4 barrel intake and Edelbrock 750. The gears I've got in my 8 3/4 are 2.92 but I do plan on swapping to a 3.55 or something similar to that size. My tire diameter in the rear is a 28" and the rough weight of my truck is 4000lbs. My question for the forums is what size stall converter to run and is the Whiplash cam to aggressive to run with my higher compression 383 to not be able to run 91 or lower. I do plan on going to set of aluminum cylinder heads in the future when I have the funds.
