5500 red line on the stock rotating assembly is a good place to start. Look to Edelbrock for a TBI intake manifold and matching Performer camshaft. That package will freshen her up a bit.

incorrect, the stock redline on TBI trucks is 4700RPM.

agreed. i think all TBI engines were 4700 RPM. i guess the flow goes into stall after that because of the shitty intake runners.

Irocs were like 5000 so 4700 doesn't sound unlikely.
