Does anyone know the weight of an all cast iron 351C? What would the weight be of an all cast iron 400?

Thanks

The following numbers come from an early Ford catalog and are for
"typical" engines.  The dimensions include such things as air cleaners, oil
filters, water pump fan, etc., but not bellhousings.

               Engine    Width Length Height Weight

               302 Boss  24.5  29.0   28.5   500
               351W      25.0  29.0   29.0   525
               351C      25.5  29.0   29.0   550
               351M-400  26.0  29.0   29.0   575

       Heads      
 
       50.0 lbs  289/302 - complete including rockers
       56.5 lbs  351C 2bbl open chamber - bare
       58.0 lbs  351C 2bbl open chamber - complete except for rockers
       60.0 lbs  351C 4bbl closed chamber - bare

Thanks, what I was really looking for was the weight difference between a 351C and a 400. From your data it looks like about 25 lbs.

Yup. And about a +3.5lb difference for 4V heads. I imagine intakes/exhaust or headers would make slight differences, too. Either way, a 302 definitely weighs less than either but won't have the grunt.

At least 1/2 of the weight difference between the 351c and the 351m/400 is in the rotating assembly due to counterbalancing the long rods/taller pistons.  P~
