Peak of 6200 cfm demand is about 290ish. 379ci
Better line of sight the speeds over the short side can be higher is what I found. I bet its pretty dam good. fast.

Look at Noonan, All Pro, Mast, CID etc.. Lots of nice stuff out. One thing is these darn things "stock" outflow most cubic in CFM demand suply. They are 15*-12* stock.. 350+ cfm stock. Most 427ci and smaller engines operating 7000 rpm or less don't want much more head.

With boost during the overlap cycle it did a better job of cleansing the chamber where the n/a combo struggled ( rpm point of peak hp ). To me it's telling me the n/a cam needed work on the exhaust side.

I'm curious whether cam designers have a working assumption that the rocker ratios being used in their models have consistent ratios across the lift curve. I would think the fact that some rocker arm brands & systems can have regressive ratio curves (higher ratio off the seat, then the ratio dr...

Spintrons and flow benches HAVE propelled this industry to great strides. Perfect? NO. But then again has anything we done been perfect duplication of a running engine? They are both great tools. One more expensive then the other BUT the most valuable tool is the operator and how he/she deciphers th...
