Does this unit give that classic supercharger whistle sound?
Also I am looking at your boss 302 forged block with a trick flow top end. I'll be using 39 lbs injectors 255 pump long tubes larger mass air and t body. Will this unit he restricted or do I need to step up to a larger unit? I prefer not to tap into my oil pan if I can avoid it at all.
You will get a nice subtle "whistle" from pretty much any centrifugal supercharger you choose.
If you are looking at forged internals and a healthy top end kit, this kit might be a little overwhelmed. This kit is more designed as an entry level supercharger system for vehicles with relatively minor mods or stock engine setups.
With those mods, I would look into the V3-Si H.O. or Intercooled kits. All V3 Vortech superchargers are self contained and don't require tapping the oil pan.
