I was curious if anyone here could tell me a site I could look at to get all the specs for my engine. I was curious of the stock HP and torque and all the rest.

stock hp for 81 305 is 150@3800 RPMs for 8.5:1 305s 165 @4400 for 9.0:1 305s (most likely its a 8.5:1)
stock TQ is 240@2400 for both.
specs for 86 is the same.

Anyone know what the HP rating would be for a 75 350. I read somewhere that it was 155 but thats what it is for a 305. So if anyone know please let me know.

Was that rating off the crank or was that done to the tires?
