I just got a 1964 327 chevy engine that says high torque on the valve cover. It has 20 thousand + miles on it and came with a transmission from a tanker firetruck (hence the low mileage). Can someone tell me what the horsepower might be. I would think it has to be quite a lot to haul a full sized tanker truck around. My nephew was going to fix the truck and use in parades but the water tank was too rusted.He junked the truck and gave me the engine. Thanks, Dave

The 327 is not a known TQ monster but it may have had a smallish stump puller type cam for use in a truck that would motivate it OK. HP in such an engine would not be too high IMO.

The 283 came in the same "high torque" format as did the 327`s. These aren`t made for horsepower, they are made for exactly as they say, Torque. They have small 1.71 intake valves and small runners which makes for high velocity at low RPM which makes it have immediate throttle response and high torque, when it reaches about 3500 RPM it`s out of breath. I`m not sure about the horsepower rating but I would guess it`s around 220.

I have a 327 in my K20 plough truck that says the same thing. The High Torque model 327's typically have the same horsepower as a regular 327 but around 10% more Torque.

May wanna look at the thread dates before replying. This one is about 7 yrs old.
My uncle had a 65 K20 with a 348 W motor in it.He use to rule the stock/street truck pulls in this area until his daughter wrecked & totaled it out.
