First and fore most I am NOT crazy for keeping a 305 in my truck( just wanted to get that out of the way first ) now I need some help on figuring out what size it now turns out to be after the bore job (.060 ) and if I can use roller lifters on it. I have a vortec v-6 that has the rollers and a keeper that I can't remember if the 305 is set up to use. I will be using a torque cam because of pulling a 24' pontoon boat. Any ideas as to the c.i. now ? BTW it's in a 88 K-1500.
