early A body engine swap

Thanks for the info! I'm genuinely surprised how difficult it is to find information about the mounts. I can't find any official info about the thickness of 2265, my local dealer tells me it's 36mm so that would be hair under 1.5". Rockauto tells me that 2469 would be 1.5" and 2710 would be 1.75" thick, so that makes me second guess the info from my local dealer. I need the replace the mounts with something ASAP just to get the car back on road, so maybe I just order pair of 2265 and try to look into the mounts and brackets with time. I would like to get either solid steel or poly mounts, but the options seem to be very limited. Looks like Moroso steel mounts are only 1" thick so they are probably way too low anyway. Maybe best long term solution would be if I try to source the 340 / 360 brackets and get poly mounts from Dodge polyurethane engine mount

Edit: After some googling I can't find anything which would indicate that there is height difference between 273 and 360 mounts, only difference I could find was with the mounting tabs.

I call them block insulators and they are the same on all LA blocks, I believe 72' and down, then they used the roll mounts (different "K" member W/loops). It's the mount to block tabs that are different on the applications 273-318 or 340-360. I would not use a solid mount on a street motor. I had issues with breaking mounts (drivers side) in my 72' Van with a 340. I installed a chain at the mount to engine and the corrected the problem. I believe a solid mount would be hard on the motor, the frame and my body. On my van, I was able to tweak the tabs (318) to accommodate the 340, but they are longer on the van than the cars, so it was easy to adjust.
