Turbo Impco 425 max hp

Hi guys, I know it's not Holden related but branching out to all technical minds.

What's max hp you think a single impco 425 will support in blowthru config?
Got an EGAS ba wagon I'm dropping a turbo fg motor in on straight gas and rather than going full injected vapour lpg, was exploring possibility of going blowthru carby and just tune factory ecu for ignition for boost.

Due to the fly by wire my gas research mixer is not happening without converting to full aftermarket ecu in which I might as well go vapour, so figured impco is next best bet.

Chasing 350rwkw so probably way out of its league. Any thoughts
