Flow Numbers
Well, to all of you that asked, I'm thinking I'm going to post scans of the flowbench printouts...
I've found the 333's (Which volumetrically, are nearly identical to the 817's, close enough so I didn't pony up the extra $$ to have the 817'a benched, too). I'm looking for the 690's I benched. I should have them shortly.
I'll scan the sheets in, and post them. Then you can check lift, velocity, and flow at all the points for the heads....
Jim- The bench numbers take into account both sides; however, we didn't measure it on the block. This was heads on a bench. From my limited understanding of the W-Motors, they've got a shrouding issue with the exhaust valve in the cylinder bore when it's open. I actually shelved my 340hp Car block in favor of a truck block for this exact reason. Who knows if it makes a difference (It's supposed to, though)!?!?!
The flow numbers were great when prototyping a motor, and later building it. I got a lot done very cheaply because my machinist was as curious as I was with these things... They actually flow a lot better than I thought...
I've got to get the page to work, and scan it... (My Scanner is not Win XP compatible, I just found out... Yippie!), then I'll post it if it's good. If not, I'll list a chart of numbers.....
