LS Swap.
Current thoughts are for a frame mounted pump with a sump provision on the tank and a swirl pot.
Plans are for a LM7 -cam upgrade, 80gph injectors...and oh yes... a turbo...
Reason for an in tank is that I have had past experience of pumps overheating (Holley) on a FI engine.
Good call on the noise, strange but hadn't occured to me :/
