So you think the top one with the cooling head is a 4.6?
Any ideas about the bottom one? Its an older one I can see
Thanks

Both look like the 4.6 v2 engine to me....

Axial and HPI crank cases look pretty similar. That first one is missing the sipes on the flange when comparing to the axial though. Although, it does look like the axial 32 spec1
