sc69sam's 1969 SS Nova!

[MosportGreen66]

Sam, love those survivor cars! They're like history books! Full of interesting throw backs. Your Nova is no exception and I'm sure you'll have a blast keeping it clean and beating it up... Are my eyes going or is that an a.i.r. system on your 350?

Just throwing this out there... was the L48 a 4 bolt or 2 bolt main block?

Any vintage photos?

The original owner has NO original pictures. I asked him a couple times. That is an AIR system. Same block as a Z/28. Glad you like it Dan.

Don't quote me on this, but I'm fairly sure the only 4 bolt main small blocks were the 68 & up 302's, and the LT-1.

[Salvatore]

Nope, 68's were 2 bolt blocks and in 69 the SS 350's and the Z/28's and the 4 barrell truck blocks were basically all the same. 1969 started the 4 bolt blocks. So when you think you are buying something special when you buy a DZ block you are really ONLY buying the stamped suffix code. Unless of course you have the car to go with the DZ block.

Yep, I have 4 0010 blocks. Three are four bolt main and came out of 4WD trucks.

But there's 010 2 bolt blocks too isn't there?.
And what's the other casting used for the 69 DZ's...and only the two used?.
And the truth on the high nickle content thing is...and only the 010's or what?.

Anyone know by chance what casting was used on the blocks shipped to S. Africa for the 100 factory installed Can-Am Firenza cars and spares?. These things are the ultimate and I've asked a few of owners of these cars for info before but only had confirmation of the DZ suffix, never any replies to the casting #'s or dates?.

And lastly, anyone have production by suffix for DZ's...I think Fran Preve listed these back in SuperChevy once?.

Sorry for the sidetrack-hijack..

Yes GM said that the 010 blocks had some high nickel contents but Blocks used were 386,010,388 and 618 for the Z/28's and the SS cars. In 67 the motors were small journal 2 bolt blocks in 68 they were large journal 2 bolt blocks and 69 is the change, large journal 4 bolt blocks. So when you see someone asking $2,500.00 for a 69 DZ block tell them they are nuts except if it is the original block from your Z/28. Sand the DZ code off and it becomes the same block that was put in that little 1 ton dump truck.

Something else people never mention is the distributor tower in the block. At some point in either late 69 or early 70 they started machining the tower to be level with the lifter valley. Sam before we get too far off subject, that is a spectacular car you have. Most cars even from California are never this nice. Your car is truly exceptional. If you go back to the Muncie mystery shifter do you want to sell the Hurst shifter?

"If you go back to the Muncie mystery shifter do you want to sell the Hurst shifter?"

What is the deal with the mystery shifter?

[WILMASBOYL78]

They call them that, because it's a "mystery" as to which gear you're in The factory Muncie shifters in the Novas and probably the other cars, were notorious for jamming and for being sloppy...the shifter partially mounts to the crossmember, so there is a natural tug of war with the tranny when the engine torques these shifters were the first thing that went back in the day....we use Hurst bodies with Muncie handles on some our cars....best of both worlds. There are some guys who rebuild the Muncie units and can make them work reasonably well...still can't match the Hurst for reliability
