Good Job Hope to see final Numbers On the BENCH and on the Track.

It just always amazes me that people forget what & where these heads came from and what they have done in the PAST and a Distant past at that.

410" Alcohol Sprint Cars (750-850hp)
NHRA ProStock Truck 358cui and 7.50/180mph 1/4 miles Turning 10,500rpms.
Nascar Cup and Busch Series 358cui.

I have a set of W9-RP (I know they are a Bit Different) but the shop that ported them claimed 400-425cfm depending on which bench they were on. Also told me I could probably get another 25cfm if I sent them to Reher-Morrison and let them run their W9-RP CNC Program on them.

I personally would like to see what the W9s are really capable of. Like a Few others I have a NIB set under my bed. LOL!

I only know of 3 small block heads that come even close to the W9's. SB2's, Mozez, and P7.

I wouldn't even consider the P5-Hemi in the running. How available is it and did they ever fix the Leaking Issues.
