All Small Six i6 250

This relates to all small sixes
Well, shit. The drop brackets sound like something I would need to fabricate. I think I've seen a few examples on this site. Thanks.
I don't have a small6, so can contribute nothing to the details. But I'd say for you not to toss the baby with the bathwater at this point. The perches your dad fabricated are plenty stout for the job. The car was used with them without issue. Yes finding "correct" parts is always desirable, just don't let that cause you to scrap everything that's already there, when that could potentially become an acceptable foundation for reuse with the necessary modifications.

I've never had an interest in putting a 250 in my car, so I've never paid much attention to the subject either. But I've seen it discussed many times, and it seems people are trying to re-invent the wheel here. Aren't there detailed instructions on what parts to use to get it done in the Handbook?
 
Following up - I found the perches I have and they look similar to those you have. The holes where the unit attaches to the frame of the car, like yours, don't match the ones on my 66. They have C7Z casting numbers, indicating that they are for a 1967 car, but the numbers don't appear in my reference document. So I'm puzzled. A browser search suggests that the part numbers I have (C7ZA-6061-A for the driver side and C7ZA-6037-A for the passenger side) are for a 1967 Mustang with the 200 I6 engine. I don't know what to believe about them. Sorry.

No, there are only general guidelines. I got my handbook and read it while I was working to adapt the 250. The handbook recommends use of Maverick engine mounts, which I found to be very scarce. Worse, they appeared to me to require some significant changes to the Mustang to make them work, so that suggestion did not seem practical. In any case, the handbook is out of print and not available.

Ok thanks for the attachments.

Does anyone KNOW if the maverick brackets bolt in if they could be obtained ? Would it solve his issue ?
 
You always run into problems when you try to shoehorn weird motors into different cars. The 250 was only made from 69 to 80, so I knew trying to cram it in a 64.5 Vert was not going to be a simple plug and play. I am having fun solving the puzzle, but there is so little literature on this type of undertaking, that it does have a tendency to be frustrating. It's amazing my dad found anything to make this engine work in a car three years out of date with no internet. A credit to him. But now that these cars are becoming less and less available, it's hard to just look into an engine compartment and see a solution. Part of me thinks it would be better to drop a 200 in it, but I pressed forward with the 250 because it has a fair amount of sentimental value and it was available. So, if I get frustrated, it's on me.

Plus, the brackets I have worked for the 66 coupe. So I don't want to spin my wheels and kind of believe, if it ain't broke, don't fix.

Funny you should mention how stout they were, because you are right. They were stouter than the engine mounts on my 302. The left side was broken for years and I never knew it until I lifted the engine and the left one fell out on the floor!
 
I have a chance to buy a 200 with a C4 for super cheap. I've never been more tempted to sell this engine. Does anybody think I can get $900-1000 for the rebuild block and head? Hahaha.

Head was rebuilt at Shreve Automotive in St Louis, MO and the block was bored and honed at B&L Engines in Sauget, IL
