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.
-
im looking at getting an 81 and was wondering the same thing...
-
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.

thanks again there stepside!

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.
-
I show 155 hp @ 3800 & 245 ft. lbs. of torque @ 2400 for 75 4 barrel 350

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