Holley motor mount issue

[MY6.2SS]

Here's mine. Not countersunk. Zoom in. Hope this helps

Just like mine. I am right up against the A/C box. Hopefully it will be OK.

Most have to do some trimming of the box

Very nice tony, not sure this picture will help him tho since you have no headers and without the body on frame but we’re all trying. Like I had said earlier I haven’t dropped my motor in yet and I also have non countersunk ones like pictured on their site but like texas82 and 82delta said if you have their whole system and it’s not a good fit I wouldn’t hesitate to call them, maybe they did send the wrong ones. Not the first time I hear of this happening good luck.

Would you happen to have any pics of the correct mounts? Something I can compare to the ones I have? Thanks, David

Looks like I have the correct ones, thanks for that pic!

You might have worn body mounts or a rusted mount hole. Something to think about.

It looks like it is about 2" to the center of the hole?

Yes. And the c10 ones they sent me fit but were 3 to the cent of the hole and the alignment tab actually raised it up a little. Luckily it wasn't enough that I had to have the drive shaft remade. It definitely got me Orr the heater box though.

I have the Holley kit and passenger valve cover won’t go on hitting the ac box. I had a tough time bolt
ing in the mounts and don’t want to go through that again. Can I cut into ac box and reshape it with fiberglass?

I think I may have posted this on another thread before but holley actually sent me the wrong mounts the first time. I installed the motor and ended up cracking the a/c bot and the motor sat a tad too high. Turns out the c10 mounts work for the gbody and that's what happened to me. After putting the correct ones in the motor sits lower, a tad more forward and the valve cover clears the box.
