And yet...... the fastest Mopar Wedges in FAST are all big cube combos.
The motor in the Duster in the pic...... the quickest of any SB FAST build(well into the 10’s)...... peaks well above 5k, and is only down 9hp 800rpm past peak.
I’m afraid anything I might offer won’t be of any help with Jesse’s plans, since my plan of attack would be the exact opposite of his.
I would absolutely positively be trying to steer the job towards using a 4” crank.
