Thread: 'Coupla Questions??

I've never actually seen a Thor crank,, but castings dont lie.
Top hat liners first thing.
new cam and followers.
You could double your spend just by headwork--



I'd like to get rid of the cat pipes,
can I assume the O2 sensor would work in the muffler?
is exhaust gas flow speed a critical component of the sensor?

well castings do not lie ,Pedro, just that they often are just that, castings. Obscurely placed for the casting tracking process, Just have to know how to read them . Stampings on the other hand are usually much more to the point and relevant.
That 4.6 on the crank looks to me more a stamping than a casting so is quite likely says what it says. best way is check the crank throw length though. If there is no other information available. Could be like a 186 holden with a 202 crank!
Cheers Scott

Pedro
the O2 sensors are before the Cats towards the exhaust flanges on both sides
so it shouldn't affect their operation.
What cam did you have installed in yours?
mine is used mainly for towing a 3.5T boat.

Turners recommend a Kent H180 in the 4.6 for towing, I need the 4.6 fuel map to finish the job.

all I know is it now goes much better than the 4L
