the most amazing part of the story is that six packs have staggered jetting stock and 85 jets make the A/F perfect in every cylinder the float bowl check screws are higher on the outboards already, so i can see the float making a big difference if it was to high

I never said WOT was perfect.....and STOCK the jetting was the SAME front and rear..... Like I said.....to tune it to it's maximum, I need to go to the track and jet it for best MPH..... but, driveability is AWESOME.........and I've got a STOCK intake, unlike the stuff you've been messing with , which I'm SURE won't need as huge of a jet spread as you have to run ....I also did stagger jet them one number from side to side, similar to stock, but didn't want to get into that in this thread.....
The Oxygen Sensor is JUST a tool......just like a timing light.......Yes, you can tune without one, but having one gets you there a LOT quicker.......
Here's a pic of the car for those interested.......The owner (Lonnie) bought it in '74 and it's an original Six Pack car..........His friend owned the car and blew the original motor up street racing it one night, so they yanked it and traded the local Dodge Salvage for a running 383 which they installed......Lonnie bought it with the 383 in it for $1,200......In '92 he installed a stock 440 4-barrel and it's been that way until I got it and rebuilt the motor and installed the Six Pack......

I bought a LM1 when they were new on the market and I just love it. All these guys that tune "by ear/hocus pocus/black magic" or whatever would get a real eye opener if they had the data right in front of them. Hands down one of the best tools I have bought in the last ten years. Nice write up Wayne. I know it is very rewarding to put the razor tune on

I installed a racepak and dash over the summer in the Duster when I installed the new 408 engine. Made a pass and checked the O2 readings and made a jet change. Next pass new best and after checking the readings made another jet change. Next pass new best and readings were close so I tried on more jet. Slowed down next pass and the readouts showed I went one to far. Whet back to the second 2nd time trial jetting and ran perfect. The next weekend we ran another new best. My only problem is that once you get spoiled by all the info you never go back so I will probably buy another racepak setup for the Daytona when it hits the track again.

I have just bought an A/F gauge for my race car but i'm thinking of buying a street car this year and wondered if the bungs can be bought separately and if i can get caps to screw in, so i can swap it from one car to another. Mick

Good read Wayne...When i get my t/a going after sitting for 5 years i'll bring it to you for the razor tune....
We can do it, Gary ......Which car are you talking about?
You will LOVE it on Silverfish.....
I've got a Panther Pink(FM3)70 T/A that i've owned since 1978...The car has been sitting for about 5-6 years after we got serious with SILVERFISH...My wife has been on my a$$ to get it back running as we've had this car before we had kids(Scott's 31)and hauled them everywhere in this car...Lots of memories related to this car like Scott driving it to his high school prom etc.etc...

Do they still sell the LM-1? I only found the LM-2 on the innovate website. Is yours a dual O2 sensor unit? Where do the bung(s) go in the exhaust? Can you explain the LM-1 unit a little better? I have heard of them but I would like to get more familiar with one. Any tips? Are there other companys? It's it a handheld unit that you can interchange from vehicle to vehicle? Just weld in new bungs.. Inquiring minds want to know!!! hahaha

Nice thread, the float adjustment comment threw me for a loop also, but the results speak for themselves.
I bought the FAST display awhile back, and while definitely more caveman than the lm1, it was definitely enough to show me I've got a way to go yet in the tuning department for anything other than idle, WOT and accelerator pump. Really need to put more time into it.

Cool......Yeah, I saw a pic of it you'd posted on Josh's board.....

Honestly, I don't know.....but I'm guessing not.....I also have an LM-2 that Innovate gave me when I did my Engine Tuning DVD......... I just use it as my backup in case something happens with the LM-1.....I just drive around with it laying in the passenger seat....

Mine is just single.....I put the bung in the exhaust right about where the front cooler line for the transmission is, on the same side of the car as the battery.....

Inquiring minds want to know!!! hahaha
It's basically just a handheld O2 sensor that spits out a number that you can watch while driving down the road.....You can also do a recording if you want and play it back on your computer, but I've never used that function......
Yes, you can move it from car to car, which is what I do......
Yes, there are other companies, but I've had good luck with Innovate and they seem to be the largest company selling them......
The thing to remember is that it's still JUST a tool......JUST like a timing light, it can't do any tuning for you......it can only tell you what the AVERAGE A/F is in that pipe from those 4 cylinders....
It's not like the average guy can just bolt it on, see what it says, and then know exactly what to do to get the motor to where it wants to be.....You still have to have a REALLY good understanding of carbs to use it to it's potential........which is another reason why I always recommend Dwayne Porter for doing your heads and camshaft....He can walk you through how to tune it and help you get the most out of your combo.....I've spent a LOT of time on the phone with him picking his brain and he's always been more than helpful..... It may cost a little in shipping to send heads to Vermont, but you get his wealth of knowledge for free and HE always answers the phone or calls you right back.....

Thanks!!! One more question. Do you put bungs in both pipes and tune each bank? Or do you just go off of one side of the engine?
Dewayne is only 6 hours away from me and I spoke to him before, great guy.
Ryan J (Shady Dell) built my motor but I am looking to get the most out of it.
Thanks, Jeff
