Inland Empire Mopar Mechanic Needed

Not for me....
A friend of mine over on FBBO has a 69 GTX 440 that he says is running like crap...
He's a little older and has a bad back and wants someone who knows what they're doing on Mopars.
He's not cheap...just wast someone local he can trust...
Any ideas???

Any updates yet? I'm curious if he has taken his GTX to someone yet. Although there could be countless reasons why it's running poorly but if he's checked his fue/ignitionl systems, possible vacuum leaks, etc. and he's having timing issues, I'm going to claim it's the crappy factory timing chain & nylon gears (that is if they haven't been replaced yet).
