Speaking of those INDY exhaust ports...................................................
The flow #'s on Barracuda's 360-2's Went CRAZY yesterday.
I sat in disbelief staring at the flowbench........The #'s were stout right out of the box, and then I hand blended the exhaust seats and did a much needed valve job and BOOM......... check THIS out:
LIFT---OUTOFBOX---REWORKED
.200"-----103.5----------107.0
.300"-----158.7----------165.6
.400"-----199.4----------207.0
.450"-----212.8----------220.1
.500"-----223.9----------231.1
.550"-----231.2----------237.0
.600"-----236.3----------244.3
.650"-----240.8----------250.1
.700"-----244.3----------257.0
Those #'s are with NO flow tube......
#'s are better than some CNC W9's I've had on the bench..... Those #'s are just crazy for 59 degree head with non raised port.
Also just FYI INDY has changed the CNC Chamber program, from the one I showed in the pics earlier. Slightly revised the area around the valve seats, to help unshroud. Chamber is 67.5 CC out of Box. I'm still working on intake #'s..... If anything, their chamber revisions helped Ex flow and hurt Intake flow some. I picked up and average of 7-9 cfm with a Valve Job on Intake side. Gonna work on chamber a little and a back cut. These heads are gonna run HARD, REAL hard....
