Re: 427 SBC Pump gas - Trying to get that 700Hp

If it were possible for you to do this you could try installing 1.5 ratio rocker arms on the Intakes only, open up the lash some, and see what happens. Are the Duration numbers at .050" lifter rise ?? Sorry if i missed this . Mark H.

Re: Drilling holes in head gaskets = more flow = lower temps: Change My Mind!

Adam, BillK stated the Facts very well and RCJ brings up a good point, the Hottest area is between the two center Exhaust ports, and plumbing water from the water pump to each Head or engine Block directly below the two ports is a good move . Mark H.
