Wilcap Slant Six to 200R4 conversion

So... its just a flat plate with all the mounting holes centered around the crankshaft centerpoint in their appropriate locations?
If that is true then I think that a NAG-1 such as what is used in The LX/LY body platform
would be an EXCELLENT swap.
It can take the torque stock and the gearing ... the gearing isnt bad at all:


  • 1st Gear - 3.59:1
  • 2nd Gear - 2.19:1
  • 3rd Gear - 1.41:1
  • 4th Gear - 1.00:1
  • 5th gear - 0 .83:1
  • Reverse - 3.16:1
And there are stand alone controllers available. Reasonably priced in junkyards.

A few of issues beyond the issue of physical fitment. First gear is way too low...people complain about the 700r4 which is 3.09. The OD ratio isn't much different than 4th, and won't drop RPM's the way the .67 in the 200 will. Finally, you'll have to pay for both an adapter ($600) and a controller ($750).
