Small Block Head Flow Chart
I flowed one of the SM al ootb intake ports
@28, 1"clay engine pro 2003.100 valve
.100-61
.200-126.8
.300-183.2
.400-226
.500-240.7
.600-247
I moved to the port next to it and did like everyone else did and touched the valve job 60,45,30...the 45 really needs to be set lower to get a good 30. I plan on doing that later today and retesting...but for now.
.100 61.9
.200-132
.300-186
.400-228
.500-247
.600-253
Then i just lightly blended the ledge @ the short turn only. "'#'s on right are with the vj lowered wider 60 , narrower 45 and wider 30 & unshroud chamber."
.100-62.3.....63
.200-132......133.7
.300-188......192
.400-232......236
.500-255......255-261 turbulence.
.600-253- it hiccups & recovers
.630-263
Only took 1 pic last nite, you can see i used a 2 1/4 stone by the minor unshroud at the chamber. ill take one of the rest and post later.
Then i added a 75 below the 60 to and then 'lengthened' the straight side of the short turn back and lipped it a hair just to the center of the ssr peak.
.100 64
.200 134
.300 192
.400 237--lengthened the ssr more=244
.500 260 cfm
.550 264
.600 255
I had to blend the head bolt bulge and the push rod pinch is opened to .950
If i calm the air speed at the window, it goes 268cfm by .550/.600
