I think something in the 224 - 228 range is appropriate
to your chosen converter and anything below .600 lift
won't be too limited by the 243s. If you go with more
lobe separation you'll make your life easier, tuning the
drivability stuff.
The Vic EFI is maybe not well matched to this though?
That seems to me more like for somebody wanting
max RPM horsepower more than drivability and torque
at street RPM. But then, in an ***-light little overgeared
truck it's not like you're going to put it to the ground
anyhow.

I was panning on running a similar setup and bought a 228/232 587/598 cam based on a buddies recommendation for a good mid range and decent driveability. Not sure if this cam would need more than 3600 stall, since i'm running a t56.
