69 Frame Motor Stands - 307 to 396

frame mounts are the same, A/B body, you need to match them to the mtr mount.

tall and narrow or short and wide.

I we compare these 2 pics of the Beaus and full size frame mounts, they do not look interchangable to me! Or, is this for reference only?

as dave said. they are both the same installed heights but must be installed as a matched set. ran into this problem this past spring

When I replaced the 350 with the 454 in my '70 back in '93 sometime, I just took the mounts of the mouse and put them on the rat..... (before I knew there was a difference) Still there today....

thats great because I already blasted and powder coated the 307 frame mounts and they are already installed on the rolling chassis. I do have a new set of 307/327 motor mounts so I can just use those, right? Just double checking because the big block motor mounts look to be a bit beafier

Just off the cuff, I would summize the insulation is twice a thick on the rat mounts because of a heavier mass and viberation reduction.. Thus the lower frame mounts........

I used mine! Just my near extinct 2 pennies, though! Other may and will sure beg to differ if you are going for the originality look!

There correct in that if you use the 307 mounts you will need the 307 engine mount as well. There are two part numbers for frame mounts for 69 as the 307 frame mount is taller than the 350,396 mount. For the 350 and 396 they used the new at that time interlocking engine mount that was thicker and would require a shorter frame mount. But you should be ok as long as you use the 307 non interlocking style of engine mount.

i tried both sets on my 70. i was trying to get the motor a wee bit higher and they don't interchange but both have the same installed heights.
