well i got a 12v awhile back. and broke it the same day i got it. anyhow.. thats not the reason for this post. im sort of 12v retarded.. ive read about them but never messed with one and dont know what works well and what doesnt. the truck is a strong runner and made 600+hp at 3900 rpm at schied this year. my question is this.. what is too much timing to drive fairly frequently. its not a daily driver. but if things start getting hairy this winter and i need a 4x4 then im gonna hafta bust out the dodge since its the only truck i have. got the truck from a friend(who knows none of the techinal stuff about the truck cause all he did was write a check). but the guy that built the truck for him wouldnt tell me the timing or what delivery valves are in the truck. after askin a few other guys that know them i found out its set at 30* timing and the delivery valves were custom cut to the builders specs by a local machine shop. im just wondering if the DV's are cut like a full cut cause it smokes driving down the road and it really roals the coal when hooked. any help would be great.
 
Sounds like full cuts, but the only real way is to pull them out.

I would guess that 30 degrees is going to be too much for winter time start-ability. IIRC there have been a few guys that have had to crank for a good few minutes before getting to fire around 20-25 degrees.
 
i guess i need to get the DV's out. are they hard to take out? never done it before. and how will i know if they are full cuts?

Get yourself a DV socket. Pull the holder and spring out carefully. The top of the DV is visible once you get the spring and holder out. Definitely be careful...those parts are small.
 
ok. how will i know if they are full cuts? is there a measurement i have to take? or some other way.. sorry for all the stupid questions im just new to the 12v's. both my other trucks were 24v's

ok. thanks man. ill probably have shane help me do it since ive never done it before and he has probably done it once or twice
 
i figured id go ahead and ask this question here too instead of starting another thread. my truck has a built trans in it too... ATS 5 star converter.. billet input yada yada yada... anyway.. it shifts into drive EXTREMELY hard. like i think its too hard. is there a fix for this?
 
Chaz, I got a socket too, I dont have much of a need for it anymore.........


Now its hard with out being there, but with the built trans, its going to go into drive much harder than with a stovker, but thats with out me being there to see how hrad is hard!
 
sweet faker. id like to get it from ya if i can. and dude its HARD.. like chits clunkin when it kicks in to gear hard. and ride... if i remember right idle is set at like 850-900 i think. id have to double check to make sure tomorrow.
 
Ok. When I had my idle up at 1K RPM, the shift to drive was pretty hard.
 
ill double check tomorrow when i get home from work and make sure. but i wanna say thats bout where its at. maybe they had to set it that high cause the way the pumps built. hell i dunno. im new to all this 12v, ppump business
 
If Im not mistaken 850 is around were stock idle is at.........

Heck, Im picking up the new rig tuesday and have til friday off. Might swing by and help out!
 
ill be here everyday after work accept friday. im headed to ohio after work on friday to take my buddy that 6spd
 
and im pretty sure i already know the answer to this but i just wanna make sure.. the trottle is REALLY touchy thats because of the 5k gov springs right?
