At a Crossroad...again. If I had only known!!!

Sell the Performer and 850 Holley. Your car will be trouble free and faster with the original cast Iron intake and any 340 OEM carb. Stock 68 to 70 340 exhaust manifolds are the way to go and lots of people will send you the stock exhaust even stainless if you want. And no surprises or headaches. How soon can you get it running? Driving? OBTW most of us suffer from this problem. I'd hate to admit how long I've had my 340 done, yet it still is in pieces.
