Some pics of the hack backyard no name head porter, look pretty good to me and the flow numbers look great, so I think it was money well spent..

I'm shocked, that on oso, with all the AFR heads that were purchased, nobody has flowed a set of these? How about any others like the 305's, 315's, 335's?

I had my 305 as cast with blended bowls flowed for my 540 builds, I don't think I have the data any more.

Did you dyno those ? I forget

Yes @ Smith power, 630hp

I was running a restricted EFI plenum, pretty sure if I had run a single plane with a 900cfm carb it would have performed much better

I was shocked too.... glad I did!!

The question that was never addressed. what do you have to do to raise your torque curve 400-600 rpm? If you want more top end out of your boat stop chasing peak HP. and work on extending your torque curve!

If he extended his "torque" curve, making more torque in the upper rpm band, wouldn't be also me making more peak HP?
