Jerry, you forgot about the head studs for another $1000.
I'm waiting to see the results of throwing a turbo on a 292.
To the OP: Turbos only work well at higher RPMs, and won't give you much low RPM "grunt". For that you need a supercharger rather than a turbocharger. The difference is the turbocharger is driven by exhaust spinning a turbine which spins a compressor wheel in the intake, while the supercharger is a mechanically driven compressor wheel, not depending on exhaust flow to spin it.
