I just fired mine up last weekend on my dart.
one thing you want to find is a 99 or earlier motor. the reason is 2 piece harmonic balancer and pulley set up. You will also need the fly wheel with the weights as they are externally balanced. I went the with clearwater heads drilled for the la intake manifold. Lot more options there and they were under 400 a piece, with the correct springs for my cam. I have a mp cam in it and hooker headers for a abody. word of advice if you are putting it in a abody go with exhaust manifolds as it will make it easier to get to put the mini starter in. Do not get the chrome oil pan for the car as it will probably not seal right. professional product manifolds are junk, I got one sitting in my garage right now that I took off due to not sealing properly.
good luck with your swap and if you have any questions pm me and I will see what advice I can give you.
