in the book it states the best bolt in lump flows in the (AREA) of 240 so the numbers you have are not far off.Again differences in numbers could be machines or altitude.But still very close. As for the rest of the numbers in the book it only shows (stock) 172 The rest of the numbers are 194 & 160 Lumped and Non Lump port and has the Intake & exhaust Port Volume along with Flow.
I can scan that page and send it to you if you'd like. and it also likes as if these test where with cams of .600 .700 .800 lifts.
So with you doing some of the test at 500-550 this is a good thing for most Hot street set ups. Because Most cams after that 550 mark become Mech. cams,-- Not Hyd.
which for the Street for most Guys that's the best way to go.
Hey Lee did you also flow that one head that you where telling me about? And did it flow like you where told it would? }[oooooo]
Ps I will be the first to say so far so good.
