AFX engine mounts

[shopguy]

For an early B body, the engine is offset 3" to the pass. side. Later B's have the offset at ~ 1.25" to the pass side.

IF buiding an AFX with a front motor plate and stock tranny mount, should I keep the 3" offset? or use the 1.25" offset that is built into the aftermarket motor plates?

What offset was used on factory AFX cars? does is really matter either way??

shopguy,in my experience with these cars,the aftermarket motor plates are generic-you have to cut them in half to use them.on my car it is close to 16.5 on one side and 17 or 18.5 on the other.i can measure it for you if you want.i changed my k-member from the 65 to a 70 e-body.i did that to use late model headers and oil pan.the offset stayed the same.i have a motor plate that is cut right to fit,with the right offset,let me know what you think,mark---you can't change the offset at the front and think it will be the same on the back

Its definitely 3" on the 65. I got that right off the Schumacher site. The 70 B/E will move the engine back and to a 1.5" offset. They "said" it puts the engine 2" lower and 1.5" closer to the firewall.

If I use my fully rebuilt 65 Kframe, I can use my 3 spd. manual tranny mount with the 727 auto, all in the same position as stock.

If I move it forward 10"....I'd have to locate the motor in the same place (at least forward) to use the tranny mount I have. I was just curious about the 1.5" offset difference.

A motor plate is looking like the think to do. It was suggested to install the engine on the K frame in the stock position. Then mark & install the motor plate. Then move the K frame. That way the motor plate is set, and the engine is in the stock 65 location.

Do you have a motor plate? or 70 K frame?...or are you using both?

Pics of mount etc...

These are the pictures of mine...if you want a picture of the motor plate I will send tomorrow. By using the '70 K-member it did move it back 1.5" but it didn't move it lower. All I did with the tranny mount was turn it around and cut the back end off so the mount would stick out. Look at pics. It didn't move it left or right at all. It just moved it back, not down.

The offset is measured at the crank. The engine actually will look crooked in the engine bay. Look at your Peddler pict, esp. at the injectors popping through. Look at the opening cut lines on the sides, and you'll see its crooked.

I'm just trying to find out what the factory did for an offset.

Mark: got an overall engine bay shot? does the engine look like its pointed crooked?

 

[moparmarkk]

Engine does NOT look crooked. Will get you an engine bay pic by the end of the week.

Here is a early B, 63 Sport Fury with a poly 318 block. I cut out the shock towers to have another set "just in case" things go wrong with our first set in moving them.

Notice the offset???

 

[shopguy]

measured bias to be 14" from crank snub to R rail, 17.5" to left rail.

There is a little more twisting than stock, as I cut the rails somewhat to remove the towers...but there IS a signifigant bias.

Stay with the original 3inches. How bad was the trunk floor in that mangled '63 Fury? I need a patch for my Polara!

This is my second afx as my first was sold to finance my shop. We used an origional hemi mount for one side and made a fabricated alum block the same size for the other side. We set the motor tranny in and used a level. The rest is cut and weld cut and weld. I like this much better than a motor plate.

howie how did ya bolt the k-member to the new frame rails?

howie how did ya bolt the k-member to the new frame rails?

when i did mine i got a peice of thick tubing, drilled a two holes per rail at the rite location, then welded the sleeve into the rail so when u bolt the k down it won't squish the tubing..

Wondered about this myself....

Here are a few pics of my ride.. It sure looks like 3" off to the side. My issue is that the 727 is on the tunnel... What do I need to do to the tranny mount to correct this problem. I also had the notch the K member for the deep sump....
