The engine.
Its located in the right(driver) side under the exhaust manifold....
There was no Camaro LT1 "SS" in 1995, but the stock LT1 (assuming you were referring to horsepower) had 275 hp.
95% the same yes. The Vette had 4 bolt mains vs the Camaro/Firebird 2 Bolt Mains and the vette had SLIGHTLY better intake/exhaust. All in all the Vette Lt1 developed about 25hp more than the Camaro/Firebird version (which can EASILY be caught up to)
Is this a Factory LT1? In your 1992 Z28?
Yes
You can purchase a Haynes Manual and it will help you with the exhaust and much more.
Yes
