As long as you're keeping it simple (sounds like you are) then it's pretty easy to do yourself. Especially if you order up a complete rotating assebly and complete heads! I used to build my own in a tiny 1 car garage years ago and had to move the car every time I worked on it but it was one of the best 440's I put together!

Take your time, clean everything and measure your clearances!

It sounds like a stroked 400 would be perfect for what you're wanting to do along with 440 Source heads and rotating assembly.

People [Edited by Moparts - Family Friendly Site - Keep it clean] about them but every part I've ever purchased from there has been really nice and bolted up perfectly!

7 quart pan, pickup, pullies, water pump, housing, alternator brackets and billet thermostat housing were all great.
