Cloyce variable timing gear sets
Hi, I'm new to your site and have questions regarding the Cloyce variable timing gear sets.
I have 97' F250 H.D. 4X4 E4OD trans, G code, XLT, 4.10 gearing, super cab.Completely original as right off the line, stock tires wheels, heavy duty tow package, even the original heater hoses, its never been apart. It has 240 K on it and I'm the second owner, I got it with 28K on it. The only thing I have changed is put Cat Back exhaust, and changed the front hubs to manual engage type. The best pick up I have ever had.
I have all the factory manuals for it as well, and still can't find the answer to some of my questions.
I'm replacing a leaky front timing cover. When I went looking for an OEM cover I was told they are discontinued. It was then that I discovered this engine was set up for California emissions. It has a crank sensor mounted to the cover. I bought a Cloyce variable chain & gear set. There claim is if you set it on the advance position it advances the cam 4 Degrees. and is suppose to give the engine more low end torque. If set at the retarded it produces more high end torque & H.P.
My question is (finally)
Are these engines retarded from the factory? How much?
I don't see anywhere it shows the torque rating at 4K RPM ?
They show the rating of 400 lbs torque at 2200 rpm, and the HP rating at 4K rpm not the torque at 4K rpm.
I tow reasonably heavy trailers with it, and usually in 4th gear, so the rpm is higher. Thats why I'm looking into this cam gear change. With out knowing what the 4K torque rating is, I don't know where to apply the cam setting.
Any help will be greatly appreciated,and sorry for the long message.
