Re: Benefits of 4-port water bypass on a SBC?

Let's face it 55 Chevy had no clue how much power would be extracted from this engine design. If they had, who thinks they would have still stuck 2 exhaust valves together in the middle of a head?

Re: 6" Rod Pistons Heavier Than 5.7"?

Funny thing is 2" journal rods are heavier on the big end then the 2.100" journal size cause the hole is smaller.again you never mentioned if you were using a small or large journal crank. [-X



That's not really true about the better stuff now is it?
