Could someone give me an idea on what jets I need. I have a pair of unlinked 38s that came with my 1980 special roller. The engine has been rephased 277. Cam rephased with aggressive street grind Coils are the green high output. Charging is PMA, ignition pamco. Custom header pipes outside diameter 1.5" with peashooters Filters are unipods. Located at sea level. I'm thinking bout getting a selection of mains and pilots., Mains I'm thinking 140/145/150. Pilots #30 or 32.5??? I'm not sure but I think my jets are the hex style. Thanks for any replies.
