350 or 400 mains for my Motown 406 build ??
I'm making plans to build a D1SC procharged 406, and I'm starting with a Motown block. I have the option of the 350 or 400 mains.
So whats the real advantage of each ???
One guy I talked to, said go with the 350 mains since you will have a ton more crankshaft options etc....
If I go 350, do I have to do all the "extra" work as far as balancing etc ( I know 400's are usually external balanced, but was going to do the extra stuff to go internal balance etc)
Any tips about advantages/disadvantages of each would be great....Ned
