Well I finally gave in and built an Iron 440 for a customer. Jim has wanted a 440 for a while and I am very much against building them due to the inherent flaws with crankshaft overlap, compression height, and rod/stroke ratio. Dont get me wrong, the 440 is a bad mutha, but it does give up longevity in doing so.
What we did was different than every other 440 that I have seen. I will not get into specifics, but it does involve a 1-off custom crank, 1-off custom rods, and 1-off custom pistons. If we are happy with the performance/longevity of the motor, we will begin offering these to everyone else.
Pistons and crank will be here by Friday and I will get some pics up then, but for now, here is the block that we finished today.
