get bigger tires, or change the final drive in your tranny?

modern fuel injected engines aren't as influenced by higher rpm's as their older carbuerated ancestors. Especially a 4 cylinder. 3000 rpm is likely close to the peak volumetric efficiency of the engine.

Did you get this worked out? It's a '94 Toyota Truck so it's a bit out of what I'm used to these days, but someone might be able to jump in.

Yeah, seems like the OP shouldn't be worried about this. Could always install larger tires I suppose though.

See the above quote, it isn't really that surprising that a '94 SR5 would run at 3K rpm on the highway at 70.
