NEED HELP ASAP !351W to 351C Swap

[macx]

for a good Windsor to build, look for a 94 or newer light truck block - they are factory roller blocks (though they may or may not have roller lifters from the factory). Then you'll have the serpentine drive system if you'd want to use it, all the right brackets, etc. besides having a block you can use any roller cam made for the factory roller engines.
