My search for a shorty D100 is over

Well it's a super cool lookin little truck. Maybe a stone stock 440 Super Commando?
You’re ok ditchin the slant 6 for a 440 super commando but not a magnum crate engine? I thought I HAD to keep the slant? They get no respect right?
I’ll say this, it is marginally better now that I adjusted the cable to pull the carb all the way open.
