I know this is an engine/drivetrain question but only one response over there (thanks messed up c-10).

Could someone with Desktop Dyno crunch these numbers for me? It's not fast but there is torque a-plenty!

Misc:
400 SB
.060 over (413ci)
Headers (1.5in diam.)
Flowmaster mufflers (40 series?)
TPI

Heads (#3998993):
Flow 150.8 int/ 91.1 exh
Diam. 2.02 int/ 1.60 exh
75cc chamber

Induction:
52mm Throttlebody flows 790CFM

Cam (Comp Cams HE268):
Dur. @ .050 218 (268 advertised lift)
Lift .454
1.52 lift roller rockers

Pistons:
dished .060 over (4.185 bore)
C/R 8.5:1 (?)

Am I missing anything?.. Thanks!
