Ryan's stage 2 don't flow 285@500
This is copied from his website for stage 4 and a 2.05 valve.

EDELBROCK STAGE 4 PORT WORK

.100"----76.0/N/A
.200"--147.0/112.1
.300"--206.7/163.9
.400"--255.3/193.2
.450"--274.3/203.6
.500"--279.0/212.2
.550"--285.0/218.0
.600"--293.2/226.3
.650"--293.2/229.4
.700"--293.2/230.8

All #'s at 28" of H20.
Ported head was flowed with 2.05" FERREA valve with 30 degree back cut on intake valve, and no flow tube on exhaust.


1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27

Livin and lovin life one day at a time
