58 FE mounting degree
I asked this in a previous post, I just got my frame back from the powder coater, where is the best place to level my frame to set my engine angle at? I used a level on the frame just under the cab to weld up the motor mounts before sending it out to the powder coater. Now that I have it back I want to make the trans mount. I will set a level on the intake and leveled the engine with the frame, last time this gave me about 5 degrees at the end of the transmission. I was also told in the last post you can use the starter for the angle. I have about 6 degrees at the rear pinion. Is this the right way to set my motor angle?

Engines are angled back 5 degrees to prevent major accidents when hit head on. They are designed to drop on impact. The carb base should be level to the ground when the engine is in (the carb base has the 5 degrees factored in). The key point is to make sure the crank centerline is parallel with the frame, and that the angle of the dangle is equal to the pinion, but not in a straight line so that the ujoints don't spin. Jniolon has a great write up on this: http://jniolon.clubfte.com/driveline...nephasing.html

I was hoping I was on the right track with the intake needing to be level with the fame? If I level the motor with the frame the carbs would tilt forward and the fan would not be parallel with the radiator. There is no mention of this in his artical.

The carb base should be level to the ground.
The frame might not be level with the ground depending on the look you want.
Once the engine is installed the pinion angle can be set accordingly as Havi said.

Yes, the centerline is a lateral dimension IE: the front part of the crankshaft and the back part of the crankshaft have to be equal distance from the frame rail, only if the frame rail is parallel with the truck.... not a tapered in rail like IHC. The up/down angle is factored in at 5 degrees. If you have a heavy forward rake, the engine will be angled back further than stock, and the pinion will be adjusted off of that as well. With a stock height, there is little forward rake, and the 5 degree lean would put the engine angled back just a little. The carb base would still be level, and the fan should be nearly straight up and down as well. 5 degrees isn't a whole lot. The intake may not be level, unless measured from the carb base. If you measured from, say the outside edge, it would not measure the same as the carb base. Not really noticeable with the naked eye.
With a big suspension lift, the rear pinion is angled upward, and the engine stays put. It's a necessary "evil" in trying to keep a lifted 4x4 driveable.... and you WILL wear out ujoints faster, lol.

Yep, that is right, ……and just to further confuse things….level the intake carb base with the ground (that is presumably level). The angle is built in to the intake (arguably 3 degrees) match the pinion angle to it and the rest will look after its self,....... because I think the frame does go up and down hills when you are driving?

This motor angle thing is very interesting to me, sorry to keep bringing it up. I went and check the angle of the motor in my 67 Mustang. The radiator is about 3-4 degrees I was not able to get a good measurement on the intake with the carb on but it looks about 3-4 degrees. The tri power on my FE is 5 degrees. Are all motors 3-5 degrees? I had a Tbird Tri Power at one time and I think it was flat. Was the Tbird motor set in the car level? Are all motors different is an inline 6 at3-5 degrees? Is this what you need to know before install a new motor setup? Still would like to know if I level the frame at the cab.
