Dave, just throwing this out there, did you ever check the plugs after a test and tune run, to see how if you're rich or lean at wot? I don't know if you'd be allowed to pull a plug on the return road or not.
Yep, heading back towards lean.

The jetting remained the same for the 600's Dave. For the cross ram I run tune # 21 in the Edelbrock book with .080 secondaries. I can't remember off hand what my jetting was for the factory 2 x 4 but I think it was a few calibrations leaner than stock I'll dig out my old log book and confirm.
Ronnie Russell posted a good base line jetting for the two four set up but don't remember what thread it was in.
I have wrote down somewhere.

Sure wish Ronnie was still around so I could pick his brain.
Me too

Thanks Ray that is it now that you said it.
I went up on the secondary's and picked up a little.
So I am a believer in Ronnie's base jetting
Now I am talking with a 409 now you guys with them big boys will need to adjust.
Maybe use Russ's % formula on how much to increase the jetting.

For the hand full of times that I have had the honor to talk with him I could tell that there are a few very lucky people to be close with him as a student and a friend.
You would have been blessed to have the opportunity to be good friends with Ronnie.
RIP Ronnie Russell

I really wished I had take more notes about Ronnie's tuneing knowledge on the AFBs, but I didn't because I thought he would out live me. I'm a Holley guy but as long as the AFBs work good on the Pack Wrat motor in the new car, they'll stay on it.
Don I would consider you a good buddy also but I know that don't carry any weight.
Hey Dave, not sure if you already do or not but a shift light is a must imo. I know the old schoolers like Grump, Strink, Dyno Don etc. used to shift gears by "listening" to the engine
, but me not being anywhere near as talented use one for the human factor. I found that even though I shifted at 5600, by the time I actually see the light and the car is mechanically shifting gear the actual shift rpm is more like 5800rpm. That's where playback tack's also come in handy.....................................................

Good point Carl
I found out watching one of my 360 degree videos that when I was shifting to second that the time my transmission made the shit I was over revving.

I'm running the 2 step, line lock, shift light, and playback tach. I've been running a 6200 shift chip and like you say, probably go a little past that ( I'm old) and use a 7000 high limit chip. I also feel these tools are necessary.
Thanks

Thinking out loud with your first gear in your transmission going with a 4.88 will make that gear almost useless.
Probably will run the 4:30 until I trash it, then go to 4:56....not worth changing until then to me for the gain.
Dave, I don't have it in anything yet. I'm still working on that. Hopefully soon.
Dave, what transmission are you running?
