Starting to look into rebuilding the 4175 Holley (9895) I have had sat unused for about 6 years now. I wonder if I should use the Holley 37-1537 or the Quick Fuel 3-206. Both are Holley kits but about $95 vs. $40. Trying to figure if its worth extra/unneed parts with the Holley kit. For those don't recall, the carb is going onto a '70 L48 350.
