Will these manifolds http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8074501361&sspagename=ADME:B:AAQ:US:1 work for a 1970 Riviera? Are they correct for the part numbers? Thanks! Troy
All big block ex manifolds interchange. My listing for 70-74 right side is 1238094. The one on ebay is for a 68 430 but maybe some crossover stuff here. right side looks kind of pitted maybe you can place ad here and find better ones. Left side number is correct. Maybe someone knows if that number came on a 70. I know some of the early 430 manifolds were actually better just not sure which ones.
