His discussion-ending statement is he would never switch to e85 on a tired motor or a NA motor that's been converted to FI without forged internals and rebuild.
I've been a bit confused by this, as we were discussing pauter rods vs. Eagle up to this point

My opinion is he is going to tune it all out for max gains with max timing and fuel on the lean side to squeeze everything out of it. That's a recipe for heat, detonation and failure. There's a reason top fuel motors get rebuilt every round. Like I said I don't fully agree with it. As far as Pauter I like them they hold 644whp and I plan to push them over 700whp
Edit: 1 more point is I see a lot of flex fuel Chevy's rolling over 100k on the hwy so why on a older model engine you shouldn't run E85 beats me. If you did switch I would not try for max hp I would just go in the middle and keep the timing at a safe point maybe -5 under max. Just my opinion.
