That sounds about right, on the radiator. Would eliminating the belt-driven fan and replacing it with electrics add more nose room in the engine bay?
Also is there enough head room for a 292? [1-3/4"+ 250 height]
Lastly, would an SM 465 work on lieu of the SM 420? 420s are getting scarce.


Every 25 years I like to rebuild that 292 just for GP
