1970 L78 Nova SS owner needs feedback.

[Schonyenko2]

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.

Tom, the 1970 Nova I have now is a 03C and has the cable throttle with the open air element air cleaner. Is there any way to tell if the car came originally with dual snorkel air cleaner? Also you mentioned something about changes in the door hinges during the 1970 model year. I need to find a lower right door hinge because the door check is missing. What should I be looking for? One last question, if a car came with the radio delete did it still come with the antenna in the windshield? My car looks as if the radio and speaker were added to the car but the windshield has a built in antenna. Sorry to high jack the thread but this is great information.

No 70 L-78 Chevelle has ever been reported as having a 163 intake,nor the later released D/Snorkle.

Mark
From what I've found on 1970 vehicles:
When no Radio was ordered AND Tinted glass was not,the clear windshield will not have an internal antenna in it.
When no Radio was ordered,BUT Tinted glass was,the tinted windshield will have an internal antenna in it.

When a Radio was ordered BUT Tinted glass was not,the clear windshield will have the internal antenna in it.
When a Radio was ordered AND Tinted glass was too,the Tinted windshield will have the internal antenna in it.

I have never heard of any 70 L78 engine having anything other than the 569 intake and 291 cylinder head, on a Chevelle or a Nova whatever. I don't claim to be an expert on Novas but the flat top 3 in the V.I.N. is not the only thing I have question about on the engine stamp. Maybe somebody with a known original engine in their Nova can compare the W on their block and see if it matches this cars. I personally think the trans stamp is good, you can even make out the 1 in front of the 0 if you look hard enough, but the engine stamp has a few things I don't think are right.

My Nova is very early 3/70 production and has the throttle cable rather than the linkage... Also had an open element air cleaner according to the previous owner who bought it from the original owner in 1972.
