... with the old engine ? No place to store it. Can't put it behind the barn with the rest of the engines since there are no barns around here. No spare time to shop it around.The Y-70 head (favored in NZ for dirt track cars, or so I've read) may be worth some bucks so I'll save it, but the stock block with 145 K miles and maybe a broken oil ring might not be of great value, so I guess it's adios and sayonara, unless someone has a better idea.

Also, the R&R shop can install headers. Saw this at MSA: http://www.thezstore.com/page/TZS/PROD/classic19c/15-6017

Says it's for 81-83 280zx. New motor has P79 head so should be OK? Will be re-using the SU's. Mix and match ?  That header sure has an ugly merge pipe though, unless turbulence is good.

That link was for wrong header, fits 280zx body etc. Engine builder says get 77-78 280z header so I'll do that.

Good catch!

There was a recent thread on a Pacesetter header fitment on a '78 auto transmission Z. He had bought '77 -'83 and it did not line up with the stock exhaust. He figured it out too, '77-'78 are different than the ZXs exhaust where the collector meets the straight pipe beside the drive shaft.
