I am looking for a matched pair of single feed holley carbs for my sbc tunnel ram, I've heard that the best are 1850's 600 cfm vacuum secondarys with manual chokes. If anyone has any rebuildable ones please let me know Thanks, Andy
Andy, I have two sets of Holley 1850 450 CFM carbs, manual chokes. They were made for tunnel rams. Not sure what your fuel requirements are for your motor. One set is new and one set needs a good cleaning.
