yep,all the old LA front fits on the engine
you need to swap in a long nose roller cam,and a flat tappet will work with the right push rods,to run a mech fuel pump
you will need valve spring with the cam swap..stock wont take much..GM3100 v-6 springs and retainer IIRC
a new intake with the correct bolt angle
and carb
the old LA dizzy will fit and same headers
the old tranny fits with the right flex plate set up
just swaping on an intake and headers makes a good improvement on them with a stock engine
IIRC there is a felpro vc gasket that can use the 5 bolt vc on the 10 bolt mag head also
well worth the effort,IMO
I run a pre-mag roller cam 360 headed 318,all stock and a Voodoo cam
worth it to just go roller cam,IMO
