The more I look at the specs for the 327F, the more and more I appreciate this small block engine. Most of you guys know I'm a dyed-in-the-wool 427 guy, but I also have two small block Chevy powered boats too.
The Torque spec for the 327F says it maxes out at 2600 RPM with 302 footpounds of torque. However, that torque curve is almost dead level FLAT from 2300 to 3200, and they did it without modern vario-cam or computerized fuel injection technology. This makes the 327F one sweet running motor. Imagine having maximum torque available at 2300 RPM, no wonder these make such great ski boat motors and heavy lifters via gear reduction for cruisers too.
The horsepower curve is a straight upturned graph, with power running from 125 to 180-hp over the same 2300 to 3200 rpm noted above. The more rpm, the more horsepower you make, all the way to 4000. The torque curve is what makes the motor so tractable, and at a low 8.0:1 compression, no wonder.
Fuel burn rates are as follows (first number is rpm, second number is gal per hour of consumption):
2200 5.7 gph
2400 6.5
2600 7.5
2800 8.6
3000 9.9
3200 11.6
3400 13.5
3600 15.4
3800 17.1
4000 18.8
With a forged steel crankshaft and 5 main bearings, this would be a good choice for a rebuild in any classic boat. |
