Chevy monza had and optional V8 If you could ever find one for factory parts, I think you need front crossmember suspension parts .as well as motor mounts I have a pumped mercury Capri V8. I rewelded all the factory seams in the engine compartment, added extra tubing above the radiator mount ,, cowl to spring tower braces. ladder reinf from 1 x 2 and 1 1/2 round tubing under rockers and seats. Angle iron under rear seat . roll bar. the body stiffened up real good but now i have to put in a stronger clutch, It hooks up so good the clutch is now the weakest link.
