Good luck Charlie, hope everything goes your way.......
Did you every hear back from Ricky @ Pro Marine on the coil refund ????
they take the money quickly but refund slowly, lol! got the ra # on monday and sent back, usually its a couple of days
Ain't that the truth Charlie, pretty much everywhere these days.........to those business's it's free money to make interest on.Quote:

You might need something custom. I think I remember seeing a lathe in someones garage when I was down in Ohio... Last I heard he was retired and bored. :)

Thanks Ken.....Damn..............."I'm BUSTED".........:eek::smiletest:Quote:

thats what i'm thinking. gary, if i get the measurements of the tip of the o2 sensor could you make an adapter that would go in the side of the adapter plate? apparently the threads on the sensor are 18mm, not sure of the diameter of the tip of the sensor, which would dictate what the male diameter would be. threw her up on the dyno last nite, that thing screams! a couple of times it flashed thru the limiter up to 7400 rpm, pretty wild hearing a 3 litre up that high. peak torque seems to be around 4-4500 rpm. his dyno doesn't give hp measurements, just hyd pressure, but was great for loading the engine for building the fuel map. now i just need to get time to go run it.
Charlie and Gary,
I found an old Denso O2 Sensor from when I did my Chevy LS swap in my Jeep.
Its tip diameter is 12 mm and the projection from the end of the threads is 21.75 mm.
The threads are 18 x 1.50. At the base there is a 2.0mm sealing crush washer and the threads above the crush washer are 7.0mm long.
You probably would want to send a sensor to your machinist just to make sure everything fits.

18 mm x 1.5 tap is something I don't happen to have...........
Charlie,
Looks like you'll need to send a tap to your machinist too. :)
Yea it's a PIA. I'm just old enough that when I first started in my career all of the drawings were in done in inches. Then I had to make the switch to the metric system yet some of the old drawings still pop up and I have to take the time to convert back and forth. Like I said it's a PIA.Quote:

There is a smaller one that uses a 12mm thread but it's a narrow band sensor opposed to the wide band.
