What are some V8 engines and manual transmissions I can put in a 1983 Pontiac Firebird SE?

thats not a cheap conversion u can do it your self but anyway u go its not cheap and depends alot on if u want to convert to carb or but in a custom electronic injection system as for the conversion to manual transmission check salvage yards for the brackets and hoses u will need there are some any way u go its not cheap but it is fun :)
