There was Viking Rob, a neeat Pomy guy with a 250 a year ago. He's no longer around. He had a US 250 with an Edlebrock manifold, no picutres though, I forgot to had them to the inventory.
Check Ebay in the states, you see a about one a year up for the offer. About 9 months ago, I saw one on sale. They are yellow background with crome machined faces. Very cool!
Try the gents on the 144-250 forum. They are out there!
At the moment, Clifford and FSPP (Mike, aka AzCoupe) order in crome rocker covers of varying types. There are older Clifford Alloy rockers around. Whatever, has to make a sensible business proposal to make an old I6 component return into production. The Edlebrock item has little chance of ever being made again.
Alloy covers are going to be made
Still doing costings at this stage ( other buisness commitments have slowed this up )
Will post when available :idea:
