Chevy 292 upgrades?

[BSabbath]

I recently purchased a 84 GMC Sierra with a 292 inline 6.

I’ve read some threads here and there. I picked up Leo Santucci’s “Power Manual” book.

Any advice on upgrading? I think I want to keep the 292. It runs well now. Not really as underpowered as I thought a V6 in a full size would be. My lady complains about the gas fumes(carb). I would like to add a little horsepower.

Intake? Exhaust? Fuel injection? Harmonic balancer?
