350 to inline 250 Swap

[2bits]

Hey guys, my 350 is bad and I've been wanting an inline 6 for a long time, so yesterday I bought a good used 250 from a 73 Nova (If I decided it properly, it is actually a 75 model) it looks like it already has an HEI coil but it is external, not inside the cap.... Am I on crack? I thought they are in the cap like usual, but this sure looks like an HEI coil...

At any rate, I am just looking for anything anyone can suggest for me to look out for generally speaking. I measured from the bell housing to the center of the motor mount on the new engine and on the truck and they are both 16 inches so I just need to get a new motor mount and it should line up fine. I need to get a power steering bracket but it came with the Alt and AC brackets already. Anything I should watch out for? I can't think of anything else beside accelerator linkage maybe.

Thanks!
