I just purchased my first Z car

1978 Z with a 5 speed

What is the stock engine in this car?

Rear end?

Hey Jeff,

The '78 came stock with the L28 and if I am correct the 5spd was available but not common... most of the 5spds are conversions using ZX trannies. Further more the rearend, if it was a M/T to start off with, should be an R200... the A/T came with the R180's.

I'm just a rookie at this so if I'm wrong someone please set me straight.

Oh Jeff, by the way, the 78 should have had Fuel Injection stock also. Does yours have carbs? A good site for Technical reads is www.zhome.com ... they have a lot of answers for production numbers, options(240Z), and stock specs.

The 5-speed is common in a 78, If it is not an auto

then it will be a 5speed.

You have an R200 3.545 ratio if it is stock.

There is a difference in the zx and Z tranny.

not entirely a true statement. my 78 is a factory 4 speed.

according to the 1978 dealer brochure, the 5 speed and the auto transmissions are referred to as "optional".
