Here’s my dilemma - one owner 1985 SS, 100% completely original. Has been in the family since the day it rolled off the showroom floor. The 305 is in theory a V8 yes, but not well suited to move a heavy car like that, not like a 350 would… hence my dilemma: should I do what I can to punch up the 305 to keep it a numbers matching car, or should I get a 350 and just do the swap and live with my guilty (but much faster) conscience?
