I need to go get it and start daily driving it again.
Wow, very rare part as it is unheard of that ANY gen v would have the provision. Im willing to bet its a "leftover" mark iv with the gen v casting. I had a 96 502 H.O. (leftover block prior to gen vi production) when i bought my '80 sub and it didnt have the provision. On a side note i have a '75 pontiac 455 thats supposed to have the 500xxx casting but has the 70-74 485428 casting = leftover block from 74 used for 75 factory cars. The factory does that and so does the aftermarket.
