I will send you a pm. I don't like to advertise what my customers spend. If they want to post it then I am OK with it. It's just not my call. Their wives might be reading

It is a good jump in power regardless of whats being driven.

Tidy packaging and clean presentation Eddy.

Clean and reliable no air pushing BS to deal with probably gets super mileage as well.

Question though, Im rebuilding my 406 and decided to stay demon carb vs pay for injection -with a wet exhaust where do you put the o2 sensor so the injection can compensate for altitude?

Nice thanks for sharing.

Thanks Uncle D.
I install the O2 sensor in the collector or riser just after the 4 pipes come together. The Mefi does not run in closed loop, so the O2 is just for my personal use in tuning. It does have an altitude compensation but must be manually completed. I have it good up to about 5000 ft. Any more and I would have to go there and do the tuning personally.

Thanks everyone else for the kind words.

It is no less reliable than the 502 Mag. However, it won't have the longevity that the 502 has. I recommend a rebuild at 400 hours. You could go longer, but the odds of having to bore it bigger are pretty good. Most of the time if they are done at 350-400, then they will go back at the same bore. Like I said, if you wait longer, the rebuild will cost a little more.
I do a VERY thorough rebuild, so you end up with essentially a new engine when it's done. Thanks

Ok How do you know?

Young Performance

Well, just like most things I had to learn the hard way. It's either the hard way or no way.
Tried to do it and sucked the hose closed, burned up the impeller, overheated the engine, had to clean out all the pieces of burned rubber, etc., etc., etc.
You had to ask huh Mike??? Don't you have something to plant, or pick, or milk???

Very nice results and excellent rigging. What type and brand lifters did you use?

Young Performance

Thanks Ben. I use Morels, Morels, or Morels. If I can't find them then I use Morels.
I have used others with success but I really like the Morels on the bigger hp engines. I haven't had any problems with them so I am going to stick with them.

Solids or hydraulic?

I'm sure it is a hydraulic roller.
