I once helped build a custom bellhousing out of a piece of 14" sch80 steel pipe and two pieces of 1/2" steel plate, and getting proper alignment and depth was a LOT of finicky measurement and layout work


Actually you are giving me too much credit for the bellhousing. I know what you are speaking about, I've done something like that too, but not with this project, it was way easier with this one...
The bellhousing(NP465) I found had correct depth for inputshaft to reach pilot bearing. Also the center hole on bellhousing had exactly the same diameter than NV4500 inputshaft bearing retainer, so it was already aligned, the only thing I needed to do was new attacment points for tranny and during the welding not to heat it up too much to avoid warp

The first time you get that beast off the ground, fly it over here and we can play. I wonder if 300hp and a fast shifting a/t will keep up with 345hp and a two stroke shifting m/t???? At least I'll have more valves....


Are you speaking about engine valves? How many do you have then and what engine are you speking about?
