The bore and stroke on the 350ci caught my attention! (4.125 bore 3.27 stroke). Sounds like a SS modified motor!

That's what I'm thinking, should be good for 9k+ rpm easily as a stocker!

9k is a little low.

I had thought that also...but the specs were not what I had thought and it gets 15 HP before hitting the track.
