Going to get a hot rod 4mil crank. Rite now I have 65.5 pistons billet cross tube intake 4p timing running 93 gas stock carbs with 280 mains and stock heads and fmf FATTY and k&n pods. What size jets will I need for the 4mil crank to run stock carbs. Or should I get 28m carbs. If so with 28m carbs what jets should I get. Thank you guys.
