My LS Conversion Dilemma:

[BANKO]

Hey Guys, I've been doing more research on how to add more HP to my car. An LS seems like a wise choice, pretty easy and cost effective to get +500hp on a wet sump application. Unfortunately in studying the impact of the conversion, it seems like I will need to touch almost every major subsystem of the car: fuel delivery, cooling, exhaust, clutch / bell housing / flywheel. I just finished a Viper T56 install on my SBC and most of the new parts will not be applicable in an LS swap.

I'm not sure it makes the most sense or "cents" :-) I'd like to get up to 500hp and think I can get pretty close in old school small block with hi flow heads, roller cam and a TB EFI. I'm considering putting a few power upgrades on the old SBC and plan a more extensive more upgrade +600HP dry sump LS conversion in the future. Is there anyway to do an LS conversion without replacing or upgrading all the subsystems mentioned above?

I'd love your thoughts. Thanks!
