Ryan Johnson is nearing completion of my new W5 head motor. When he is done he is going to dyno and tune it for best performance. What do you guys think the HP numbers will be???

The specs so far...

48 degree R1A 340 block with bushed lifter bores and partially filled
Fully ported W5 heads (flows 339 @ .700) angle milled to 16 deg
498 W7/W8 intake fully ported
950 CFM Proform carburetor

K1 Technologies 4" 4340 crank with 2.10" GM journals
Crower 6.125" middle weight billet I beam rods
Diamond flat top pistons
Custom bullet 48 degree camshaft (109 LSA, 264/268 @ .050")
Crane ultra pro .903" 48 degree .210" offset solid roller lifters
Custom manton pushrods
T&D offset rockers 1.8/1.7 ratio (.693"/.693" lift)
Comp 955-16 pacaloy roller valve springs
Manley stainless race valves
External oil filter and cooler
110 Sunoco race gas
Estimate about 13.5 to 1 static compression ratio.

And a picture of the motor at this point:



So... let the guessing begin!!!
