Welcome to the club 350, sounds like the 383 will be a beast with those heads bolted on.

A 220cc head on a SBC averages out to 1.8489" diameter when you back calc the maths. Not enormous, with a 30thou over bored 350 @ 6500rpm it equates to 298.45fps calculated average. Individually some areas will be faster and some slower.

G'day 350 tunna, welcome to the forums. I have found this to be a great place, you'll enjoy it. Just on a side note, is the injection in your avatar what you intend on using on your 383? Not being a smart arse or anything but that factory type set up will absolutely KILL your top end performance. Great for bottom end torque but no good up top. You may want to look at a different setup if you're after strong all round performance.
