AC spark plug application

[Tommy_Mathison]

I've got a bunch of NOS AC Acniter spark plugs in the OLD AC boxes. What are the noteworthy spark plug numbers (LS6 L78 L89 ZL1 etc) I should be looking for in the lot?

Here is a 1969 (http://www.carnut.com/specs/gen/chv69.html) chart. Then in 70 the hi perf models had tapered plugs (T). I'm sure someone will correct me if I am wrong..

Thanks for sharing that Darren!

R43T for the LS6. I would be interested in them if they are for sale and are correct in appearance.

I've got about 10 sets of R46T's... close. Close is good enough right Rick? http://www.yenko.net/ubbthreads/images/graemlins/grin.gif

Nearly every single 1970 to 79 GM vehicle,(including Trucks),that came with a 6cyl.,used the R46T spark plug,then they all went to the extended tip R46TS after..
