« on: October 10, 2010, 09:41:51 PM »
Guys i was told by an ebay seller 69 Z28 Distributors used two different slots, early Aug 68 to Feb 69 used the CCW532. And the Mar, Apr, May 69 distributors used the CCW 530 Slot. Is this true, i thought the 69 Z28 Distributor used only the CCW532 slot. Please help me out, need some expert advice, thank you

Gentlemen did Chevy from the factory use the heavy duty morse link chain and wider cam and crank gear set? Its a heavy duty set, wider plastic cam gear and wide crank gear that was used on the 67-69 model years, is this a legit factory install or a over the counter buy at the  GM delearship?

Decoding/Numbers / Chevy BB Oil Pump numbers location?
« on: March 01, 2010, 05:16:58 PM »
Where did Chevy put the part number on BB Oil Pumps. Was it cast in the bottom plate? I am trying to locate a oil pump and the person said just because the numbers are cast in the housing and plate doesnt mean thats the pump number. If so how did Chevy identify the oil pump then? Help.

Originality / 1967 L-88 Aluminum heads painted from the factory
« on: February 28, 2010, 05:02:48 PM »
Did Chevy paint the L-88 Aluminum head orange from the factory? I saw pics from cars that had these heads painted. If so was it a thing that they disguised by painting them, or just something a owner of the car did? I have an old pic of Grump Jenkins 67 Camaro SS that he raced in i believe in stock eliminator and it showed the engine and the head were painted orange. Its the 396-375 engine, i am thinking its the iron heads no doubt, but again did he swap these heads out in favor of the 67 L-88 heads? Whats your take guys, ever heard of the factory Aluminum heads painted orange?

Guys i have a pair of 842 heads. One head has a cast date of 69. The other head has no cast date, i am thinking this head is a service replacement. The only numbers i could find on this head are 5625, the other one is 4025, what do these numbers stand for? Is this some kind of a cast number? Or is it a replacement number they used?
