Flyingskibiker is correct, 337 = Dec 3, 5 = year 75. NOT a service replacement!

Item # 330407044697 listed as a 68 z/28, BUT, the block is #3970010 and a 2 bolt. The book says a 3970010 is a 69 and a 4 bolt?
? Don't know the block date code.

General Discussion / REPLACING STOCK 302 Z/28 30/30 CAMSHAFT
« on: February 23, 2010, 05:04:55 PM »
OK GUYS; What is the best camshaft to replace the old Duntov 30/30 cam? Either flat or roller, keep in mind I'm trying to stay close to the original specs of the 30/30. Anything to 'lookout' for? This is for a 68 Z/28 302 original engine.

The closer the better, between the engine assembly date and the build date.

General Discussion / 3917610 Intake Manifold
« on: February 17, 2010, 05:31:36 PM »
I've been looking for a 3917610 Intake Manifold for some time now and some that I've seen have a portion of the middle section(below carburator area) cut out. Any reason for this? Racers trick? Better fuel distribution?

No, but I think you should look for something with a June date.

Thanks, my trim tag says 04A(1st week of April 08) so engine would have been assembled probably 3rd or 4th week of March 68.

Does anyone know if GM had a slow-down period of casting the 3917291 heads? I've been looking for a set dated mid March 68, and it seems like there are lots of 67 castings and 68 May-June, but Jan Feb and March 68 castings are almost non existant.

Did the original rally wheel trim ring have a slotted or round hole for the valve stem?

General Discussion / Re: VIN Registrary

Old yeller; what are the date codes of the rally wheels? According to Jerry MacNeish's book, early production 67's with rally wheels had no date stamp! It wan't until Feb of 67 that dating started. So if you have dated rally wheels, they were put on later and not original.
