Ando76, mate I just joined this forum (hi) to add my experience
I recently had a sbf 363 dart block all the good stuff inside and it was built with a hv pump
The engine was built for burnouts, I did one 2 min skid and the engine grenaded... Why ? Oil starvation
Spun 6 bearings broke one rod knocked the bottom off2 cyls damaged cam, just a mess and I beleive if it were not for the hv pump it would still be going
That was with.003 mains and bigends with 7lt sump
Rebuilding the new engine now but unsure if a std vol mellings is ok? I see there is mellings select pumps but can't see them in Australia?
Anyhow thanks for your time cheers
