onyx_riddle Posted May 8, 2012 Share Posted May 8, 2012 Anyway.. It's in a bad way.. It's pretty sweet. It's not worth the parts im about to stuff into it but... so? Anyhow I have a couple of questions. One, if someone swaps in a 350 with a t350a trans, would 3800rpm sound right for 65mph at the stock 4:11 gears on stock tires? It sure wasn't a fun ride home, especially since it has apparently needed valve seals for a very long time. I slowed down to keep the load low but it was chugging about 1qt of oil per hour at about 2800rpm. no matter, I'm looking into a much more -ahem- "financially intensive"- approach to bringing this beast beyond its previous prime. Mechanically inclined individuals just haven't given this car enough attention, sadly.. Anyhow, i guess thats my only question for now. Thanks guys!!

getoffmyinternet Posted May 8, 2012 Share Posted May 8, 2012 (edited) They never are. People ask me how much mine is worth and my first response is always, "You mean to me or the rest of the world?" MPH = (Engine Speed in RPM) / (Total Gear Ratio) X (Wheel Circumference in Inches) / 1056 Your tires must be about 23.63" tall for that to make sense. Sounds pretty reasonable to me.

And funny you put it like that. We picked it up and drove it home (3.5 hr drive that took 5 hrs.) And when we got it back to my home town, my wife looked at me and said "what would you sell this car for, right now?" (knowing full well that ive been planning to buy one for almost 10yrs) ... I looked at her and said " truthfully, not much less than 5k$"... She apparently wasnt expecting that response Quote Link to comment Share on other sites More sharing options...
onyx_riddle Posted May 8, 2012 Author Share Posted May 8, 2012 hmm im a cdl driver so ill have to figure it out later when I can get near it. but I dont know where I got 4:11. I think its probably a stock rear for an auto 76. Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted May 9, 2012 Share Posted May 9, 2012 4.11 is not stock on an auto 76, most of them had the 3.54 or the 3.9 Quote Link to comment Share on other sites More sharing options...
Leon Posted May 9, 2012 Share Posted May 9, 2012 4.11 is not stock on an auto 76, most of them had the 3.54 or the 3.9 Incorrect. ALL of them had a 3.54 R200. The 3.9 R200 did not come to the US until the '80 ZX. Quote Link to comment Share on other sites More sharing options...
getoffmyinternet Posted May 10, 2012 Share Posted May 10, 2012 In that case I doubt you have 20" tires... Quote Link to comment Share on other sites More sharing options...

The 3.9 R200 did not come to the US until the '80 ZX. actually not quite true, yes your right on the 3.9 that was my bad. 260Z 74 MT (3.364) (R180) 260Z 74 Auto (3.545) (R180) Now I'm not sure if the 2+2 makes a difference or not. The OP should spin the tires to make sure incase the person he bought it from did not change it out at one time. Quote Link to comment Share on other sites More sharing options...

I have no idea why you're bringing up '74 specs. What I said is correct, ALL '76 Z-cars (whether 2+2, coupe, auto or manual) came with a 3.54 R200.
