68 Cuda 383 vs a 360

I am in the process of getting a 67 Dart GTS on the road with a 383 and a four gear. I have no experience driving it (hope to get it there shortly), but you can check out my build thread in my signature to see the things I had to deal with. I got the TTI long tube headers and they are a pain to get it in. The engine does have to be removed from the mounts and raised to get both sides in. If you are working with an engine that is already broken in (TTI says not to use their coated headers for break in) I would suggest putting the engine on the K frame with the trans and headers attached to it and lower the car on to it. Would be less of a hassle. I took measurements of how high my car had to be to squeeze the driver side header in, probably would be a little easier if you could get more room under the car.

I also installed factory power steering with my set up. TTI says their headers do work with factory power steering. Well I had to dimple a couple of the pipes to get it to fit but it is close. Real close. I may end up getting a smaller steering gear to gain a little more clearance but with everything in the engine bay and no access to a lift I am dreading ripping everything out to potentially swap steering gears. Plus Id rather get it on the road and enjoy it before regulations start to change. When it comes to power steering pump you will have to use a Federal pump. A saginaw wont work due to the line connections hitting I think the motor mount. THATS THE OTHER THING!! the motor mounts. On 383 a bodies they had bosses cast into the block on the drivers side right below the head. If you get the motor mount that mounts to that you are stuck using the federal pump. But if you go with the 440 a body drivers side mount that will mount to the oil pump boss area and may be able to run a different power steering pump. You can find those pumps and get the brackets new. Just be careful and get a big block pulley. They are different between small and big blocks.

again, you can look at my build thread since my car is being set up similarly with a big block to what you are after. Biggest difference is my K frame was originally for a big block.
