360 build, hp and compression thoughts!

Hello folks, well i built my first motor, and just curious what your thoughts on my horsepower and compression might be???

Its a 1973 360 out of a motorhome, i did a rebuild and these are my specs.

KB107 pistons.
COMP.XE268 cam, lifters, pushrods and double spring kit all shimmed within .004 of each other.
Edelbrock performer intake.
Holley 4160 600CFM
MSD 6AL BOX
MSD Pro billet distributor
MSD 8.5mm wires
MSD blaster 2 coil
340 heads, 2.02 valves
Hooker comp. headers
3" exhaust all the way out
Flowmaster series 10 mufflers
Both cables Lokar
Melling hi volume oil pump
Gasket matched everything
Hughes 2000 stall
Transgo -2 shift kit
Aluminum radiator


I have approx 135 miles on it so far, compression checks 150-152 on all 8.
Running the 2 light silver springs on distributor with black bushing.

The plugs seem a little light, curious about maybe a little bigger jet?
