Where's the Wow?

Hey guys,
Got my car back together finally and the engine is a major disappointment! It is a 360 and my old 318 was better. I'm not expecting 13 second 1/4 s but I can barely spin a 225/60. Runs smoothly though. Some advice would be great!
1972 Dart
1974 stock 360 short block, with 34k. Still had crosshatch in cylinders. Pistons down .080
X heads cc'ed at 68, .029 head gaskets. Should be low 8s for CR? XE 268 cam.
Edelbrock 600 with 71 340 intake, Edelbrock square to spreadbore adapter plate. 70 340 exhaust manifolds with 2.5 inch with h pipe exhaust.
24* initial timing, all in at 2200 for 34 total. 3.23 rear, 904 trans, Pat Blaise high stall 360 converter, may be too low? Cranking compression is between 140 and 150.
Any ideas?
Sure;
1) Did You block the exhaust crossover in the intake, if so, You may need to fatten the jets up(or skinnier rods) a bit.
2) Where did this eddy 600 come from? I would check the float level & make sure it is up where it belongs.
3) While the engine would appreciate 9:1 plus, that thing should be killin' the tires w/140-150 cranking regardless.
4) As above, recheck the valve timing & be sure You didn't miss by a tooth, but if You centerlined it, ..............
5) How much liter preload is there, did you check?
