My first classic Mopar!
Welcome from California.
Your driveline is identical to what came in mine. I changed the cam to a Lunati 10200701 and intake to edelbrock performer and a 4bbl holley and destroyed my 7 1/4 within six months. A S60 from Cass at Doctordiff.com was only about $300 more than an 8 3/4.
