my timing map looks nothing like stock van or truck both of which have less timeing then i currently do.
06 van has -2.0 to 0 * timing at part throttle
06 truck as 0.0-3.0* timing in same area

I have approximately 25,000 miles on these pistons now. The first 20,000 of which were running a single 68mm GT4094R with 125% over injectors, decent power tune, and probably 20-25 sled hooks.
The last 5,000 miles has been with twins on, just dynoed this weekend at 750rwhp/1334ft-lbs torque. I don't *****foot around on the road, when I do drive it I'm usually tearing it up. Plenty of rolling burnouts and launches. So far, so good.
Virtually no blow-by or other indications of wear or cracking.
:thumb: so far!

Well , got an email from Jon , forged pistons are done ! Motor should be together soon now , can't wait !
'bout time we heard from you boy! :thumb:
I'm pleased it is all working out for you. This engine is one of the earliest with the pistons.
BTW it does have a very, very unique noise as mentioned above.
At idle it runs smoother than any stock or built engine I've ever heard, and I've gotten the same comment from others who've heard/ridden in it. Which is even more surprising given the 125% over injectors and the relatively high rail pressure I'm running to running to cut down on smoke.
Revving up it also has a very unique noise, almost louder I'd say than stock or regular cut pistons. This may have something to do with the RDL xtreme log headers, but definitely a different, sharper "snap" to it, almost more like a gasser with an open exhaust.
Thank you very much sir, that means alot to me.:hug: I love it and will be buried in it!
Keep doing jumps without your helmet on and that may happen sooner than later:rofl:
Lol, you haven't seen anything yet... FYI, at 4500rpm in5th gear my truck runs 162mph...

You run 41" tires?
welcome to Indiana.....we run hard on back streets here.....I consider IN and IL the same until I80...
Simon did you just quote yourself??

Yup, I was thinking wow those gear drops are impressive ! But fudged my math with wrong inputs
