Alright, I know that there has been extensive talk about whether or not you can drop a 440 into a small block sub frame. And if memory serves me correctly, the answers always change between yes and no. Or yes it will but the transmission doesn't line up right. I have a chance to grab a '74 for cheap but it also has a small block sub frame. I would hate to drive half way access the country to get this car and then find out I can't drop in a 440. A few people have mentioned the engine mounts from Schumacher. All I'm looking for is a definite yes or no. If I buy a 440 with a 727 mounted to it, can I pull out my 360 and 727 and drop in the new pair with nothing more than an engine mount swap? If this is somewhere else on the board I apologize but I couldn't find it in a quick search through the forums I expected them to be in.

I did this swap and the engine mounts aren't necessary. I could've re-used mine from the 440, but I replaced them, not with the Schumacher mounts, but with aftermarket stock-spec 440 ones while I was at it. The biggest difference is that the transmission doesn't mount up the same way. I'm going to have to fabricate some better mounts for them, as my transmission is slightly misaligned.
The 727 on a small-block will not bolt up to the one on a big block, so you have to re-use the transmission from the big block.
Also, watch out for the hood clearance. A high-rise intake won't allow the hood to close with an air cleaner on it.

I was thinking that I would just suck it up and get the schumacher mounts. That way the transmission should line up properly. I wasn't planning on a high rise intake. Maybe a six pack down the line, but never a high rise so that shouldn't be an issue...
It looks like all it claims is that you can put a big block in a car with a small block subframe. It doesn't say that the final result will have a big block in the same place it would have been if the car had a big-block subframe.
It says: > On some models, this may interfere with the factory A/C option.
Well, what the heck does that mean? If I was going to re-use everything, I'd want the motor in the exact same place in the engine compartment, so that the trans and all that stuff would be guaranteed to fit exactly.
So maybe a good question for Schumacher is: "Will these engine mounts with a small block subframe put my motor in exactly the same position in the engine compartment (such as in relation to the firewall and hood), as the motor would be with stock 440 motor mounts and stock 440 subframe"
If the answer is anything but "yes", then you can decide from there.
Or, you could just get the smallblock subframe and figure it out later. You can always make it work. It's just a matter of how much effort.
