Stroker numbers nowhere near what I thout it should be.

Hi, everyone!
I'm first time poster. Also Its my first Tj build.
Im looking for some opinions on my stroker build. I feel my dynoed HP at the wheel is way to low. I purchased most the parts from Clegg. I had the stroker built at a local machine shop.
I hope this doesn't come across as being paranoid, however the parts I built I feel should have gave me much more HP.
Im wondering if they actually madie it into the motor.
Please advise.
List of parts:
Stage 3 Hypereutecitc piston .060 over.
Hasting moly ring.
Scat Crankshaft.
Scat 4340 connecting rods.
Clevit rod and main bearings.
Balanced Rotating assembly.
Stage 1 cam kit with howards lifters.
Clegg/ harland, roller rocker arms
24lb injectors.
62mm throttle body.
FlowKooler water pump.
Melling oil pump.
Work done:
I wont list every thing.
Resurface block deck.
Resurface cylender head.
Ballanced parts.
Port heads.
Bore to .060 over.
Valve grind.
Dyno results:
Compression test: 160 per cylinder.
Last dyno pull,
hp - STTPrw Max 171.1.
STPTrq Max 220.5.
Lamb_1 Max 0.875.
I'll be honest I have no idea if these numbers are good or bad.
Im a home mechanic, learning as I go.
Im wondering if my cam is not aggressive enough.
Thank in advance!
