A little background into the transmission code and what it means:

IIRC (FS5W71B)

F = Floor selector (R = Remote selector)
S = Special overdrive top gear. No "S" than its a direct drive 1:1 top gear
5 = Number of forward gears (3, 4 and 5)
W = Warner Synchros (C = Servo type synchro "Porsche type")
71 = Centre lines between Main shaft and countershaft (others 56mm, 63mm)
A = Suffix number (Version: A, B, C, E & H).

I had Rebello in mind for some reason.  E88 head?  Did Floyd do any port work on the head?  There could be a lot more questions.

Stock 260 head; I believe that is a E88.  I asked for polishing.  The valves and seats were cut.  I cannot say for sure that the head was ported.

I would think that with some carb tuning, advancing the timing, and a better dizzy you should see another 10-20 hp. I base that on our L24 street/track engine with triple 44mm and a similar build as yours. We got 210@crank running 110 octane at 34 degrees advance with a CR of 12:1. The L28 and 3.2L engines in full race mode make 294 and 345@crank respectively. Those run between 13.1 to 13.7:1 CRs. We use a 75 dizzy (vintage rules), an MSD box, 8.5 Magnacor wires and NGK non-Iridium plugs (race fine wire instead).

Where may I ask did you get your R180 LSD? I would suggest a 3:70 or 3:90 ratio diff to improve the driving experience.

Sorry, I missed your question.  I bought the R180 LSD from Bob Sharp Racing when they were selling off parts from the early Z race cars.  They said it was a racing spare.

If I'm asked which 5-spd should I get and what diff to go along with it for general street use and perhaps some track time I would answer:

a 1980-83 non-turbo 280ZX (or "B" tranny as opposed to a 280 coupe or 2+2 "A" tranny - the one with just one rear tab near the tail) and the R200 3:90 diff that was in that same 280ZX.

Floyd Link also worked with Ed Pink and Nissan in their VRH Indy race engine program.

Oh by the way... Which one's Pink?

Sorry. Couldn't contain myself any more.

Link and Pink, sounds like characters off  The Andy Griffith Show.  They could've been two of the Darling's.

My early 1974 260Z was recently run on a chassis dyno to tune the Mikuni 40PHH carbs.  The tuning is not complete.  But, so far, 139 bHP and 143 ft lbs have been measured at the rear wheels.  Based on the following drive train description, what are realistic performance expectations?

Thanks

I have that exact camshaft. I told Racer I wanted an autocross cam and that is what he ground for me.

Oops. just saw the date on the build sheet.  1974.  Wow.  That was just a couple of years after BRE disbanded if I read my internet right.

To be clear though - is that "Production date" for the factory engine or the Link-built engine?

Floyd built the head in 1983.

1983 is still ~33 years ago.  You were right, time to get that thing tuned and drive it.

Priorities change over time.  I'm going to feel like a young man again.  I wonder what happened to the little Italian girl that graced the passenger seat.
