It is a hydraulic camshaft, Not a roller cam.
Chevy did not start using roller cams until late 1995
The 92 did not have a roller cam in it.
A 5.0l 305 v8
YES it does and it is a roller cam and hydraulic lifters.
A supercharger would have a dramatic effect.
Yes it will, as long as you are swaping from a 305 to a 305.
yes it will but you may need to change a couple various sensors and maybe motor mounts but otherwise will bolt right in
You do not want to change from a roller camshaft to a hydraulic flat tappet cam! that would be adding friction to you engine(bad plan). you can go from a flat tappet to a roller cam but no one offers a kit to erase technology, or subtract horsepower.
the g20 should be a 350 and I believe the caprice is a 305 you can swap the engines but you will also probably have to swap the intake and exhaust manifolds
The 305 was standard in an 89 Caprice Classic, so the answer is obviously yes.
yes
3.480"
Yes, but you will need to change the prom in the computer and you may need to make adjustments to the fuel system to compensate for the larger fuel injectors.
