253 hp?

[monaroman76]

ok..... i am 17 years old and i have a 253 red motor in a HX Monaro wid the following specs
-465 holley
-stage 2 crane cam
-oversize valves
-edelbrock inlet manifold
-ported heads (i think)
-stainless valve seats, for unleaded
-genie extractors
-electronic ignition

i ran it on the dyno and got a dissapointing 92.8 kw at 4000 rpm, is this normal, what should it pull? i thought it would pull 100's.
