No starter-issues after switching to IMI hi-torque starter IMI-108 purchased at RSB motorsports (20 USD below the regular price: http://www.rsbmotorsports.net/product.asp?pf_id=IMI%2D108&dept_id= ). I run the R.A.R.E. long branch D-port factory headers including the correct R.A.R.E. oil filter adapter with my 400 cci and TH400. Nevertheless had to switch to one of the smallest oil filters available (FRAM extra guard PH3675; http://www.hardwareandtools.com/invt/5853155# ) because of limited space... Less than 1/2 inch of clearance...
