I used an 82 mm crank with chevy rod journals in my type 4 and and only have 0.020 clearance between the cam lobe and rods. Cam has 0.500 lift on a 1 inch base circle. So a 90 mm will limit the lift or your cam a good bit and require lots of case material to be removed. The 78.4 will almost be a drop fit with chevy rod journals.
