i would have posted this in my thread but it got closed, i actually was pretty damn drunk at the time, but i was curious as to whether or not chevy designed them with the same bolt pattern for the block as the 3.1/s (i know damn well the 4.3 intake wouldnt work & that the stock wouldnt, but i know a LOT of gm engines have compatible/semi compatible parts, and just the thought of a true vortec 60* just makes me smile lol). just an explanation for anyone who read that thread & was thinking how much of an ass i must be for not knowing that the 90* and 60* engines are very different.
