So has any one done an article about the commonality of parts between all the GMC Big Block V6's? I'm mostly interested in the 305 as that's what I have available to me. The supply of larger ones in my has either dried up or eludes me. Which is the most desireable? Which one has the best parts availability etc.... thanks in advance for all of your help.
