1970 Z28 intake, carb, heads and air cleaner find

[Furback]

Found and purchased 1970 Z28 matching carb, intake and air cleaner. All off the same car. Also a pair of 492 2.02 heads, straight plug. The strange thing is the dates on the heads are 1971? Guy told me everything came off the same car. A 1970 Z28.

492 Heads are over the counter double hump heads, I don't think they ever came on a car stock. They should all have angled plugs. 70 Z/28 should have 186 heads.

Three head casting I have seen on 1970 Z 186, 492 and 041. They are straight plug.

492 and 041 heads could have found there way on to a 70 Z motor, but the only ones from the assembly line would be 186.

186's are Original Z/28. 041 Heads are 350/295 and 350/300 heads. 492 were over the counter from GM which is why they have the 71 date code.

492 was a common head casting in the 1.94 and 2.02 versions. If they are actually a 71 date then they would have to be under the counter. There are 70 Z cars with 492 heads, they were used in 69 and 70.

I can guarantee you that No car came from the factory with 492 heads. They were over the counter and Racers used to buy them and throw them on 327's all the time. It was Grumpy Jenkins favorite head. The only possible way is if somebody ordered a CE replacement lt-1 block and maybe a set of 492 heads. They are also all angle plug, so something is fishy with those heads.

I think you should do some research. LOL

^^^^^I agree, no 492 angle plug heads on a 70 Z/28. They came in several versions thru the years produced.
