I was curious about your rear leaf spring set up. Traction bars and no overloads?

Caltracs and factory leaf springs with overload removed.
I use strange 12 way single adjustable shocks relocated to the rear

Just got it back off the dyno. We were fighting a fuel pressure drop turned out one of the walbro 450s was weak. After replacing the pump we tuned the boost up one more psi. Made 976hp 821tq on 26psi boost

You guys certainly have it figured out, and to be honest, **** like this just makes me throw rocks at my truck. I made one pass at 26 psi with mine, and even though I was having to launch at only 7* of timing ramped over 1 second to get it to leave and the head gaskets where already trashed on 7 of the 8 holes, my mph and weight would suggest that I probably wasn't making more than 100 or so horsepower more than you guys.....and I'm on a built 408 with a solid roller cam.

You have more stroke and bore, your gonna lift sooner.

And your engine feels like it's making far more than 100 more... what is your drive loss from the blower? 150? More? That means the cylinders feel like they're makin way more power... that's where a turbo becomes hugely beneficial at these power levels.

Great run!
