I seen several v6 to v8 swaps done. None had a special frame, so like ccz145a said, we need pics. The v6 is just a v8 with the fromt 2 cylinders cut off. It will be longer, so I dont understand you measurements as being a problem. You should just be able to bolt the mounts to the frame, the clamshell mounts to the engine, and drop it in. Give us some pics so we can see what you see.

You shouldnt have to cut anything. The guys I have seen do this couldnt fabricate a flat plate. We just need some ics, who knows, you may have something way out of the norm. You should just be able to bolt the rubber mount to the frame and the clamshell to the engine and drop it in.

I don't know why you are having a hard time with this. Definitely add pix when you can. I took some pix of my mounts today for you but haven't had a chance to put them up yet since I just got in from working on my 74 all night (again). I'll try to post pix tomorrow

I don't know why  ??? I've done plenty of V8 conversions and never had to change anything other than the motor mount position.

I haven't ever had swap issue either other than just moving the mount around.  I would really like to see comparison pics, but...

he shuldent have  ran into the same probs 2x4 an 4x4  are way difrent but i could defently c where he would have trouble like i said i bought new  motor mounts and robd the frame mounts off another truck .   the cross members are riveted in but all you need to do is take off the suport bracket (just unbolt)   and the frame mount bolts right in to the cross member its so easey but i could have pulld my hair out till i had it figured out   ;D ;D ;D
