My main concern is compatibility with the existing engine. I'd like to avoid having to switch to different lifters, springs, etc etc.
New cam, back together, tune and
Still need the diff ratio.
You will not have to change anything other than possibly injector jetting with any of the cams below.
Snausage can make that cam and send it to you if you want but it is not what I would use.
You can order other cams from the US.
You can buy many cams in oz . In oz, VPW Warehouse sells some Comp and Cranes and APD sells Cranes and Crane may sell direct there.
Ok, it looks like they could have paid $1200.00 usd less for a set of AFR 205 fully cnc ported heads and gotten quite a bit more power out of it . DART says your heads die out at .600" valve lift . AFR 205 heads die out at around .700" valve lift, and have more flow.

Here's some solid roller cam options . I would use the Comp 35-770-8 . It will have around 500 crank hp and will do the 1/4 mile in around 10.8 seconds if you can get traction .
YOUR SNAUSAGE IS ... 290 290 . 230 230 . lobes 365 365 . rocker 1.7 . 620 620 . lsa 114
These are the alternative cams that will work for you . I would consider for your engine.
