I hope Christi is tiny.

"After some research I have decided to use a 450 bottom end so I am in a quest for a 450 motor. The frame has been secured but not obtained. Its from an AHRMA racer.
The current plan is to "graft" a 748 head onto a 450 head. A super short stroke 249cc will emerge for this odd combo but, it will deliver the winning hp and rpm we need.
The reason for the 450 bottom end is because it will fit the piston we will use for the 748 head. The great news here is that we have the room to install big flywheels to reduce unwanted pulses, making it easier for Christy to accelerate. The limitation is that the OD of the valve perimeter being 84mm. With repositioning ($$$$$$$$) we can get it to 80mm but I am not counting on that although there is room for it. Its going to be plenty of machining work in any event!"
Sounds like a lot of machine work to me.
