    I'm having issues with a Holley 650 double pumper. Engine seems to flood or not start. It's was on the car when I bought it and it's given me problems since day one.

    Is anyone running the Holley Hi Ram on their LS swap? I have a 2" cowl hood and ordered the TCI Pro-Touring front end.

    Guys , can you help please. Numbers on my carb are 4781-6 which indicates it's an 850 Double Pumper but what what does the 6 indicate? I have been on the Holley web-site and most numbers go up to 4781-5 but I cant find anything indicating 4781-6? Any help would be much appreciated, thanks.

    Looking to upgrade to a 4 barrel on my basically stock 1975 with a 350. Anyone know the CFM rating on a stock Rochester 2 barrel? Wondering if a switch to a Holley Street Avenger 570 cfm or an Edelbrock 600 is going to be a noticeable upgrade. Thanks.
