Drive train offset poll

[69MOPE]

I have seen a few different offset numbers used over the years. What measurement do you use? A-body drive line centerline is offset toward the passenger side of the car 1 1/4" , 1 3/8" or 1 1/2" ?

1.5

Closer to 1.25... If you want to get real technical it's between 1 1/4 and 1 5/16 measuring out 8.75 rears.

Its actually angle degrees offset so the total will vary with length of the drive line.

I think thats wrong.

I'm running a 440 in 71 A-Body with an AR Engineering CNC Machined motor plate. The plate by design offset's the engine to the passenger side exactly 1.375 inches. Also running TTI Headers which fit very nicely with the proper offset of the motor incorporated.

Yall are all wrong. It's a portasnorkle off to the right and a peedlepod away from center.

Go measure some rear ends with a pinion centerline gauge and get back to me...

tti header instructions say the difference in measurement from each frame rail should be 2.5" which is 1.25 offset, but, that's a real close shot and 1/32 or 1/64 isn't going to make a difference

I have only done 2 Rear ends for an A Body on the same car. Both were shortened. My calculations on both were in between 1.25" - 1.375". Don't matter which rear you use the offset will always stay the same.

I measured my stock rearend and got 2" offset. I measure this Ford 9" and get 4.125". I measure transmission in car and get 2"

Whatever it is, from the engine's standpoint, it's just barely enough at the best of times

 

[MOPARMITCH]

Its just a skosch to the Starboard Side.

 

[sscuda]

According to the folks who made my rear axles it's 1 3/16 ths for A bodies.

 

[duster360]

1.375"

Just realized this poll is almost 4 years old.
