Another engine question :V

[thirteenwithinfinity]

The 267 doesn't seem to take to hills too well. At least mine.

Is it just the fact that its a little underpowered that it struggle uphill a little or could there potentially be a problem with the motor? Theres alot of hills out here and generally, its a workout to get up them between 35-45 mph.
The car moves but it runs around ~190ish degrees. I'm used to it running anywhere between 140 and 160.

Could it just be the fact that its a 3 speed that it runs higher in RPMs and therefor hotter? :V

going up alot of hills puts quite a bit of strain on a motor, especially a 267. how many miles are on it?

190* is normal on a stock motor. but if it ran in the same conditions at 160 then i'd do a radiator flush, maybe a new t-stat.
it sounds like the engine is low on power. first check the spark plugs and other tune-up components, including the o2 sensor if equipped.

Honestly, I have no idea.
The car, itself, has 200k on the chassis.

The motor came from another car. So I don't know anything about it other then the fact that it came from another Malibu with alot less milage on it.

Worn cam shaft?

i think it'd be better to look and test the usual things that reduce power before jumping to major issues.
did you check the tune up? i saw your hydrocarbon post, have you checked the carb or tried adjusting the idle mixture screws?
