383 build no power

Engine was rebuilt when I got it here are the specs

70 challenger
9:7 compression
Old 284 484 cam
2000 stall
3.23 gear
215/70 14 tire
Factory 600 holley
Factory intake
HP manifolds

Car will not even think about spinning a tire. it has no power at all. I have a pertronix 3 distributor that was curved by don at fbo he curved it to be all in at 3200 could this be the problem, I am almost ready to just yank the cam out and replace it with one that would suit me its a show/cruiser not looking for high rpm.
any suggestion

Normally Rhodes would be a great idea. But
I'm not sure those are such a good idea for this app.
I guess the OP would have to decide if he can handle the clickity-clack.
