The 305 I'm taliking ab had 4 barrel carb stock. I think it is ho. But either way to me it seems the better choice, correct me if I'm wrong but the longer a engine sits it's more likely for seals and gaskets to rot. And I will not be taking the Pistons out of the 350 to replace rings or pistons. And the 350 was not a 4 barrel I think. Wouldnt the 305 be the smarter choice? And oh, which transmission do you guys think is better? 350 turbo or 700r4?
