410 Gears Recommendation - Page 3 - ZR-1 Net Registry Forums

WARP TEN · 02-03-2018

Agree--I love the cigar. Racing (either drags or top speed) has been a very small part of my enjoyable 20 years in the ZR-1 world. I put 4.10s in the '93 when I first got it and in the '95 when I got that as well. I was very happy with the resultant increase in driveability via the roughly 18% torque multiplication improvement that 4.10s offer. While it is nice in 1st gear, I found the improvement in 2nd and 3rd and even 6th was great as well. I also added horsepower, to about 450 in the '93 and Marc Haibeck's 510 package in the '95. I thought the 4.10s went fine with the increased power. I think Marc installs mostly 4.10s, but also the occasional 3.73s. You might call him to get his thoughts on it. --Bob

Any thoughts of using taller wheels and tires, ie C6Z, should be accompanied by installation of 4.10’s. That gets u back into the same ballpark as the stock 3.45s
w 17” wheels. 4.56s can even be a consideration. With the 4.10s, I’m turning about 1900rpm at ~ 80mph cruise.

Isn't that Bill aka Grumpy Jenkins of early Pro Stock fame?

Paul,yes it does feel "peaky" as you say.
The only thing 4:10's did was 60FT but lost it with extra gear shift.

Plus i like to run to 160MPH in forth gear

391ci will be going together next week i'm excited

, i will take pictures.
Maybe article for our mag.

Today, I'm leaning toward keeping the 345s and more HP. (How's the 390 coming?)

Yes, that’s the Grump back in the day, getting it done the old-school way with the hammer down rowing through his 4 speed M22 with full authority.

I like the chicken wing action before the 2-3 shift. Then he puffs the cigar when he hits the traps. Classic.

Just to throw it out there I went with the 3:73 on my 500hp car and it fits my driving style perfect, no racing just street driving. I had 4:11 on the 90 I used to have just not my style.

Wasn’t the Lingenfelter recommendation 3.90s?

Try Randy's World Wide...used to be Randy's Ring and Pinion.

I like my 4.10 with the light weight flywheel. Around the Atlanta area its all about street light to street light racing. Who ever gets to the next light first wins. Of course more HP is always welcome.
