New to me 240z

[IdahoKidd]

I got all the legals squared away yesterday on my 72 240z find. It is factory orange and white and the only rust anywhere is on top of the fender over the right rear wheel. Body shop friend of mine laughed and said "it is nothing, easy easy fix." I put it up on the rack and see that it has two pipes from the engine to the exhaust tips with resonators in the middle. I am guessing this is the "twice pipes" I have read about here? The car apparently has an R200 with a 4:56 posi, 4 speed and an L26 with an aluminum flywheel. PO said it "comes out of the hole damn fast but tops out about 100". I would think that sounds right? He said 60 mph is about 3000 rpm. The tach in my 280 doesn't work so I don't have a reference at all. I haven't rotated or fired the engine yet. I am told it runs but I did find two rebuild kits for the su's in the back. He also told me it has a diamond cut head? or a diamond shaped head? (it has an e88 head) and part of the reason it is parked is the installer didn't shim the cam. Not sure what some of this means (I do understand the shimming the cam bit). Any ideas?

Since this isn't a matching numbers car:ermm: I have several engine options. I have a known good low mile (rebuilt) 240 motor from a same year car setting on a roller cart and right next to it is a 0 mile rebuilt l28 motor (originally destined for my gray 77 280). Which motor would you recommend? It will be a daily/recreational driver. Speed cost money and I am poor so what I have is largely what I will have.

While my neighbor doesn't share my enthusiasm with the new arrival (4 Z's, 2 Volvo's, and IHS 120, and '52 Windsor Deluxe in the project patch, I am pretty jazzed over this one.

For a daily driver I'd say either engine will do but lose the aluminum flywheel and the 4.56s.

Stephen,

Don't be hasty in dissmissing those 4:56s.... I'm sure there are still some stumps to be pulled in northern Idaho. Now if he could just match up with a granny low gear 4 speed....

FWIW....60 mph will be well over 3,000 rpms. I have a 4.11 rear w/a 4-speed and 60 is somewhere around 3,400 for me, so it'll be higher with the 4.56's (I'd guess maybe 3,700).

Probably snap your neck taking off, :laugh: but very high rpms on the highway.

SBlake,

I am have decided to stay with the 240 engine from the same year car and keep the rebuilt l28 for the 77 project it was intended for. I am curious why you dislike the aluminum flywheel. I know I will loose some torque but should pick up rpm response. With the deeper gears, torque isn't an issue (I don't think........). Besides, the '57 International S120 with its inline six and 6:13 gears will grunt any stumps in the neighborhood. I have located a 5 speed from an 80zx (non turbo). Am I correct to assume that the flywheel (stock) is the same for the 280z and the 240z? I have spares for the 280's, non for the 240.

The light flywheel will improve throttle response, but is worse for keeping a smooth idle if it's a street car. In my opinion, unless you are tracking the car or drag racing, it's not much of a benefit.
