Nice billet pair is 2800$-3200$ depending on who you ask. Bigs asked 2790$, I already asked. Also it’s 4-5 weeks waiting time but at this point time is no problem for me.
My suggestion is get online or call blp and get yourself a couple builder kits, the carbs are f'n sweet and if rat bastid doesn't mind, could you please post a pic of mine. 850 that flows around 1000 cfm, I added 12 hole annulars also.
