427king,

Chuck, I need your email address. The site states you have met your limit on PMs.

Hi Al, The VIN stampings on the engine & trans are different, at best one or the other is not original.

No red lines in 70. White stripe only. I can see in your photos that it had a SS tailpan. I can't see the holes in your before paint pics. Did you change it, or are the holes still there? I was thinking that the motor changeover happened later in the build year, somewhere around Jan. That Nov might still have 840 heads, and 163 intake etc,but I could be wrong. Most body changes took place around mid Jan.
Some will buy it without docs, some won't. Have you tried to find the original owner. Being somewhat connected to law enforcement, you may have a shot.

Not to be critical but why put a hydraulic cam in an L78?

[WILMASBOYL78]

291 heads and 569 intake are correct for that time frame....I don't know of any 70 L78 Novas with the older 840 heads or 163 intake. It is true there were many changes mid-year....door hinges, throttle cable, smog plumbing, F41 sway bar, etc....our black 70 4spd engine was built 1 day after this one and it has the 291's and 569.

Shouldn't the crank pulley be a 291?

What information are you looking for? I thought the L-78 would have a steel not a cast crankshaft? I did not see any mention of the type of pistons used, forged or cast and what compression ratio? When you say reconditioned on some of the key parts does that mean the parts still have the original part number stampings and are they original to the car? Can you provide pictures of the core support?

I won't argue to the death on the heads, but I thought that some early novas had the 163 intake with the open element air cleaner. Does your blk nova built a day after this car have a dual snorkle air cleaner? Does it also have the arm/rod throttle? My dual snorkle late build had the cable. I thought other than the cable being a saftey in respect to a broken motor mt holding the arm open, that there would be a clearance issue with the arm/rod and the dual snorkle and the intake height.
It was my thought that the cable, and the D/S air cleaner came at mid year with the other changes. Some of those spurred by the introduction of the new camaro model.
So can you tell me when the drop dead change date is for the cable, and the D/S air cleaner. As it's possible that this D/S air cleaner is not correct for this early built car.

As an FYI, I made the air cleaner myself. It is not original to the car but I loved the look so I added it.

Ken, our car has the original open element and throttle arm linkage....the change over for the throttle arm to cable took place around the end of Dec/69...our black car is 12C and it has this and our red 70 is 12C and it has the cable, so I would say santa brought GM the cables just in time for the holidays ...2 of our other L78 Jan/Feb dates had original open elemnet air cleaners. As for the 163 intake....it was not installed on these 70 engines...I have talked to several people with early cars (sept/oct) and they have the low rise 569...I think the dual snorkle was phased in during the spring of 1970. Another place to check on the intake would be 70 L78 Chevelles since they were all early production...I have never seen a pic of a 163 on a 70 Chevelle....perhaps Rick can confirm this.
