108 lsa cam installed at 102... where's the low end loss? Oh wait, that's the same thing being done for 40 years and what those new fangled thmpr and whiplash cams are doing.
Jeez this broken record stuff. Most of the crappy low end performance is ALL in the tune where most people don't have any idea how or what to do. Oh the book says 5 BTDC for timing... yep, runs like ****, bad cam choice. Seen it what seems like a millions times.
XE262-268 or the voodoo 700-703 would likely work OK. Just make sure you degree it in and I would maybe move it forward to 104 ICL on the larger of those grinds.
