1974 Duster build
What push rods did you end up using? I have the same set up and need to figure out what rods to use with roller rockers. Did that A999 trans have a solenoid on the valvebody? I have one and it turns out to be a LU with OD with an 88 casting date. Is (Comp Thumpr Hydraulic Roller Tappet 20-601-9 ) your cam #?
What made you swap out cams?
