The intake port went 368cfm at .700 and 375 at .750 but is very unstable...just can't get enough area in the port to slow it down enough for higher lift flow and stability. It bounced between 371 and 376 cfm but managed to stay there for the test. After .750 lift it dropped down to 367 or so.
Yes they come from TF with a 2.19 valve.
Brian, my guess is then you shoot for max lift ACTUAL at the highest stable flow point? So a cam with say
.750 gross, .730 actual would be best if the port goes flat at . 730 but stable?
