You didn't burst my bubble and you are right. I stand corrected. I had a long post typed out to you regarding my thoughts. It was one of this posts you are very proud of. I was completely done with it, then I lost wi-fi connection. Anyway, I lost it. I got so upset, I almost threw my iPad though the window.
Anyway, its thanksgiving. We all should be worried obout other things besides corvettes. Or better yet, not worry at all. Lets put the techno devices down and enjoy our family..........happy Thanksgiving to all....................

I have an 85, z51 and SOMEDAY I hope to tell you what I think. But that ain't today. It hasn't been on the road since I bought it, LOLOLOLOLOLOL. Good luck with your decision, I'm sure whatever you do you'll be happy. KC

If I am not mistaken, the 85 has a neat one year feature on the tach, when it drops below 1,000 rpm, the x100 drops to x10 and the tach will read big numbers, like 89 for 890 rpm. Some 85 owner chime in, it has been a long time since I had mine.

I don't know what kind if post you had prepared, but I have to say that my 86 Z51 4+3 which I purchased new has been the most fun of all my cars.

I didn't realize it was a one year only but yes my '85 tach display does that.

Congrats on your "new" 85. I was lucky enough to have actually bought a new red/red Z51 Corvette on Halloween, 1984. I have had a lot of Corvettes since then but that one was one of my favorites. I actually found my original car on ebay a few years ago, but it was too far gone to justify buying and trying to restore.

It should... high compression 427 with big port aluminum heads and big solid lifter cam versus a 350 which meets then current emission standards. The 86 would embarrass the L88 at everything else, and probably with the AC turned on too.

I did and it is still 240 hp for the 1987 roller lifters.
Everything I have ever read said a 5 hp increase to 240 for the 1987 year.

See here for example.

I have a different interest in the early C4 suspension, I'd like to pick up an '84 or '85 Avanti II and adapt early C4 underpinnings to it. I'm in the research phase which means I've been surrounding myself with early C4 facts. Anyhow, back to the topic; here is C4 suspension information in one location as a reference point. From Hib Halverson's chart:

1984
FE1
63.5 N/mm front, 72.0 N/mm rear spring rates (≈362 / ≈411 lb. per in. front / rear)
24mm solid front, 20mm solid rear sway bars
Z51
102 N/mm front, 87.5 N/mm rear spring rates (≈582 / ≈499)
25mm solid front, 23mm solid rear sway bars

1985
FE1
54.0 N/mm front, 39.9 N/mm rear spring rates (≈308 / ≈227)
24mm solid front, 20mm solid rear sway bars
Z51
63.5 N/mm front, 57.2 N/mm rear spring rates (≈362 / ≈326)
30mm solid front, 24mm solid rear sway bars

1986
FE1
51.8 N/mm front, 39.9 N/mm rear spring rates (≈295 / ≈227)
26mm tubular front, 20mm solid rear sway bars
Z51
66.5 N/mm front, 57.2 N/mm rear spring rates (≈379 / ≈326)
30mm solid front, 22mm solid rear sway bars
FE1*
54.4 N/mm front, 39.9 N/mm rear spring rates (≈310 / ≈227)
26mm tubular front, 19mm solid rear sway bars

Z51 spring rates were softened for 1985 though its sway bars were stiffened. Then for 1986 the front spring got stiffer and the rear sway bar got softened.

* = convertible
1 Newton per millimeter = 5.710147 pounds per inch.
