Thanks Jerry very much for that info. I wondered why these types were not installed from the factory in these engines. Appreciate your help and honesty here Jerry. From a customer of yours, thanks again.

Thanks John, appreciate the info. Apparently these heavy duty sprokets and chains were availiable over the counter at GM High Perf catalogs. Some one on ebay is selling this set and claimed these came on the 302 Engines from the factory. Thanks again for setting this straight.

Originality / 302-Z-28 factory original timing chain and gears

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?

Jerry congrats on setting the all time ET record for the 302 Z-28. When i saw this posted i couldnt believe it. Your Z is sweet. I always loved the 302 motor and what these engines can do and compete against big engines and out run them. I followed your stories and its incredible. From a customer to you, keep up the great work.

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.

I guess i answer my own question, lols,according to the Corvette action center web site, all 1967 L-88 Engines were unique, valve covers, cylinder heads and block were painted orange. Any other input is greatly appreciated about Grumpy Jenkins engine, i like these vintage drag cars.

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?

Restoration / Re: need Chevy BB high perf oil pump- used or new

« on: February 26, 2010, 07:01:55 PM »

No not concerned about the height of the gears. I just want an original  oil pump that matched the 6 quart deep sump factory hi po pan. IF i cant find this pump i need, i do have an 3969870 ZL-1 oil pump. It has the 1.3 high gears, will work. Again its an originality thing with me, that oil pump i like to get would complete the  package. Milling gears is way to much unwanted work that isnt needed. Again just looking for the correct number pump 3946023 GM made back then.

John thanks for the info. I am still hoping someone has one on the shelf thats been used or new and wants to sell it. I saw one on ebay a few weeks back but the pump was long gone, sold.  I understand they dont make them. My other plan is i purchased a oil pump #3969870 , a GM pump used on the ZL-1 Motor from Summit Racing. This pump has the same gears, 1.3 as the pump as i was looking for so i would be all set. Checked with Dennis Tracy, Tracy Perf, he couldnt find one in his inventory either. I know this is a hard pump to find.

USER 3965175 you are wrong about this oil pan application. This oil pan was used by Gibb perf cars after original blown motors, 396 were pulled, and this pan was used in place of the factory 4 quart. Go to the Supercar Registry Bullentin Board and read up on this pan and its history by the guys who used thses pans on their Novas and Camaros. I believe you are the same poster who posted on the Supercar board and said these pans were never made by Chevy, sorry you were wrong then and wrong with this application.

Decoding/Numbers / 842 Aluminum BB heads cast date?

« on: January 29, 2010, 11:15:33 PM »

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?

Jerry is exactly right. These pans were never installed on factory Camaros, Novas, Chevelles. I was told from an excellent source that Fred Gibb Chevy perf installed these pans after modifcations. Go to Supercar Registry Bulletin board and there is a complete thread and history on this pan. I have two of these pans and a windage tray and oil pickup tube and screen that goes with it also.
