depending on the compression (trucks got lower CR), I'd say about 300~325.
IF your compression is in the 8.5~9.5 range, and the rest of the engine is in good condition:
start with the oiling mods and a HV or HV/HP oil pump.
New cam and lifters in the 214~235 @ 50 range and 520~580 lift range.
Performer RPM intake or simular.
Block off exhaust crossover if the intake doesn't.
Port the heads or have the ported, remove hump in exhaust roof, grind down the valve guide that sticks into port, blend and smooth the bowl just below the valve, unshroud the valve.
If you haven't already, update the ign to electronic via Pertronix or some other kit.
