The Edelbrock 650 with Camden SC thread

Hey everyone!

The time has come to discuss my next supercharger project.

Parts list:

•Edelbrock 650 Performer Series with electric choke (1406)
•Edelbrock calibration kit (metering rods and springs)
•5" Camden SC ('05 model)
•RB collected header
•narrow band AF guage
•Carter fuel pump
•Holley fuel pressure reg

Gonna boost the REPU!

Just a small question about compressions ratios. The stock early 13B rotating assemblies of REPUs were 9.2:1 CR. I also have access to an S4 T2 assembly which I think is 8.6 CR. Which assembly would do me best for towing and off-boost performance, such as under vacuum conditions and low end torque since it is a truck?

Oh and for RotaryDave, the SC curently has a -7 pulley, but is going to get a -10. I'd like to know whether the T2 assembly ought to be used. Will it be beneficial or a bad idea? Thanks!
