318 LA torque?

you got that right
my 360 is on a 112 but it's a mopar master not a chevy so the timing's shorter\
problem with low compression is the wide lobe centers close the intake even later mine has a true 9:1 with Iron heads and a towing application
you do not build compression till the intake is completely closed
one reason the factory hyd cams suck is the very long closing ramps (for anti noise reasons mostly during long warranty)
