Yesterday I picked up a Winters foundry Holley Strip Dominator. I'm attempting to find out when it was made. on the bottom 01147 last set of numbers. Was this made in 67, 77, or 87 ? LMK when you have the chance and thank you for letting me post.
77 or 87, the Holley intakes came out in the 70's. And are still producing some of the more popular ones today. They are good quality intakes, better casting quality than Edelbrock.
Only a guess, but I’m thinking Winters cast the very early production manifolds for Holley so I’d say your manifold is from 1977. Either Winters couldn’t keep up with the quan***y needed or maybe Holley went shopping for a cheaper source.
I have all 3 , I would have to go look for Low S D Holley Logo one on china wall. The other on coolant runner. Also Winters in different locations First pic is tall S D 2nd pic medium S D A Tall S D with 4500 with Winters Pro Dominator No Winters
