From further digging due to too much free time Ive found that Id need to delete the ac/or notch frame and a tighter clearance oil pan. As far as reasoning. Bone stock supercharged motor will be more reliable than a boosted SOHC 2V with powdered rods. 390hp would be plenty for me, so swap, tune, done. Something peppier than the stock 250hp 2V and a 6 speed would keep me happy in a family DD. I was thinking that or Cobra short block on 3v heads with an M112.
