I'm using an off the shelf Comp Cams 231/ 231 .617 .617 114+2 in a crate LS3 in our 2001 Monaro, which weighs in at 3880lbs.
Ancillaries are 25% under drive, RAMJET OTR, 90mm throttle body, 1 7/8" into 3" collectors, 3" cats into 2 1/2" twin system, 4,500 convertor and 4.1:1 diff gears.
Any thoughts on this combo?

Why fixed?
lower overlap(only 3*)
IVC later at 47* degrees instead of 44.5*
EVO later for a longer power stroke
less chances of surging
less succeptible to reversion
better torque production
I thought you Ausie's like low and mid range torque?
And add a tranny cooler if you have not for that 4500 stall and heavy Morano.

Compared to our old LS1 this feels very "torquie", and yes I've had a tranny cooler for a couple of years now.
