SBC Swap Cost?

Just a general question, for a car that could easily fit a sbc (jeep xj) how much would a reliable swap cost (mainly just engine and trans and other notable expenses) for a handy person who could do the work themselves and fabricate the necessary things like engine mounts and body modifications.

Nothing crazy; As far as power, just a NA 350 or something, maybe around 300-350hp and a manual transmission. I’m assuming that would require pistons rods heads cam and exhaust right, would a crank be necessary?

I know it’s not easy to predict the build cost but just a rough estimate for building the motor and sourcing a trans if the work was all done myself.

Thanks a lot in advance
