he has a IA 20.1 re 18" 1/0 guage run to second bat and from second bat to amp he has 1/0 guage also. plus we did alty to bat in 1/0 plus bat to ground 1/0 also

Engine block to chassis in 1/0??

there isn't a chassis it's a unibody

Run another batt..Get an HO alternator??

he has 2 yellow tops and that ALT might be his next upgrade

There should still be a frame up front, the engine cradle or sub frame, whatever you want to call it.

If 2nd battery is grounded to the chassis the engine block to frame/chassis up front might help.
