First post and not sure where to ask. Close to finish on my 69 Mach 1 and muddling my way thru Holley world. It ran fine before hibernation and had a 1850-2 on it. On the Holley website it looks like an 1850S is an exact match, manual choke vacuum secondaries. Not on a super strict budget but I did look at the factory refurbished and they never have any. Any thoughts on the 1850S ?
