'72 engine, tranny, etc - how much are these worth?

[goaldangoal]

I'm looking to buy my first Z and recently spotted a '72 for sale with extra parts. I was curious if anyone could tell me how much those parts would go for if I bought the car. (Hopefully to defray the cost somewhat.)

'72 240Z

Engine

Transmission

Dual Carburetors

Alternator

Louvres

-- and some other miscellaneous parts

I saw a similar post for 2+2 parts, but no prices were actually mentioned, so I'm still up in the air on whether to go for this or not.

Any advice at all or ballpark figures for those parts would be extremely helpful to me in making a decision.

Engine - tough to sell sometimes because shipping is so high

Transmission - if it's a 4-speed you'd be lucky to sell it

Dual Carburetors - dual SU with intake may go for $100 depending on condition

Alternator - not sure but probably not much

Louvres - for the rear window, $20-60 on eBay
