1969 DZ 302 Windage Trays
Hello, was the windage tray that bolts to the 5 main cap studs on a DZ motor a late introduction during the model year? Did the 67/68/early 69 Z28's not have them? Thanks

I've got a DZ block with a May casting date that has the 5 studs for a windage tray. Am looking at a January casting date DZ that does not have the studs- just bolts. Just wondering if the earlier blocks originally came with a windage tray or not until later production '69. Thanks

According to everything I've read, all 1967 through 1969 302 engines had a windage tray. My 1968 302 has one..Joe

I wonder why someone would have replaced the windage studs with regular ones. Odd.

All 67-69 Z28 engines came with the windage tray & studs, and Z28 oil pan. I have taken apart many original 302 motors over the last 50 years and everyone had them. I worked in a machine shop in the early to late 70,s, and we specialized in Chevrolet HP .
FWIW - Original line installed windage trays are different than a lot you see for sale, they had a round hole for the dipstick instead of the elongated slot type opening. |

The block in question may have been robbed of the studs for another block and motor combination. Look at the bolt head markings on the 5 positions and see if the head markings differ, usually all head markings are the same on all caps on original motors.
