OK......my last test on the flowbench after opening
the pushrod pinch to 1.010" netted the following:
.100"_____62.9
.200"____127.0
.300"____187.9
.400"____229.1
.500"____251.3
Backs up over .500"
With valve job and a Ferrea 5050 2.02"
.100"_____66.2
.200"____119.3
.300"____176.5
.400"____231.6*
.500"____271.4*
.550"____280.3
.600"____285.2
346.5 fps @ push rod .650"____285.2
Backs up over .650"
* Slight turbulance.
Same port but added a 30º back-cut
.100"_____68.0
.200"____132.0
.300"____187.6
.400"____240.1
.500"____273.5
.550"____282.9
.600"____282.9
Backs up over .600"
I will say this.....68 cfm @ .100" is
the most I've ever seen from a 2.02" valve.
Must be the nice chamber work.
The push rod holes are getting plugged and relocated.
