New Member, need some help. Good battery, no start, no power.

Yes, I know has a Dodge Demon front hood and grill on it. I got it in this condition. I have an original Shark Tooth grill but just waiting to get the quarter panel rust repaired on the lowers. The car is mini tubbed and has 325 MT ET on the rear. There is no data plate on the fender but original H code 340 on the door tag. Not much more I know about it but has a Holly 4779-2-1569, and Edelbrock LD4B intake.
