The 5SFE and 3SGTE share the same effective rod length. The big end bores differ, however, so you don't machine the crank to fit the block. You modify the crank for the rod you plan to use. 5S crank with forged 5S rods and 3S crank with 3S rods means no machining necessary, 5S crank with 3S rods will require you to machine the rod journals on the crank.
Awesome! I hope you continue to do research and make this dream a reality for yourself when the time comes.

Thanks Sang, I think I'll use the 5s crank with forged 5s rods, that way no machining is required..but thanks when i get started I'll let you know so you can help me just incase I get stumped since I'm still learning.
