Ls next 390ci Have an 800hp tunnel rammed Ls next built at 390ci
13:1 compression
Lsa forged crank stock stroke
Manley h beams arp2000 bolts
Je dome pistons and 13:1 comp
Pro filer heads
Race fuel
Will be cammed to suit boost if I boost it
Will I have dramas to boost it now with low boost and race fuel
Either pro charger or turbos

I'd say the cam is bound to be horrific, at least for a turbo application.
Maybe with a centri blower it might be ok.
I'm sure with some great fuel ( methanol ? ) you could add some boost at that CR, I wouldnt be getting too greedy though. And no doubt the pistons will not be very robust in terms of detonation resistance being a n/a piston.
It's just not asking for boost at all as is.

Make sure your back pressure is 1:1 or better (think huge twin setup). If that cam is right for the motor NA... generally it's right for the motor in boost. Methanol fuel would be a must. 12-13:1 is pretty common with methanol and boost these days.
