Details:
The motor is a 393 cubic inch Cleveland street build with SCM aluminum heads and SCM dual plane intake manifold.
The compression ratio is 11 to 1, and a Pro Systems 830 CFM carburetor is sitting atop the manifold and a 1/2"
4-hole spacer. The camshaft is a solid roller street cam spec'd out at 242°/242° duration at 0.050", 110° LSA,
0.639" valve lift. The exhaust is handled by 1-3/4" tri-Y headers having 3-1/4" collectors, the ignition timing
is 18° initial 28° total.
The beast runs on pump gas. 560 BHP at 6600 rpm is respectable, but there's a few things that caught my eye. First,
this power and that strong top end was accomplished with Scott's dual plane manifold. I don't think that motor was
out of wind yet! The pull was cut short at 6600 rpm because the motor is brand new, only 8 pulls on it so far.
Second look at how wide and how flat that torque curve is! That is classic Cleveland performance. These things say
a lot about the combination of Scott's heads & manifold. The horsepower curve is very linear, and not too steep.
What do you think, does this Darin Morgan designed induction system rock and roll?
