will the motor run if the cam gear is off a tooth ??? im talking about GEN III motors....

 

I would think not...no compression if they are out of phase. If it did run I would think it would pop out of the throttle body or exhaust.

Yes, it will. It will run poorly however. That is actually known as advance or retarding the cam timing. On race engines, it's common practice in engine tuning. Most all of the Gen3 cams have 4* of advance built into them, so anymore will usually negatively affect the performance.

I'll move this to the performance section. Maybe someone who knows more about this than I will expand for some clarification and symptoms.

 

the reason why im asking is i had the truck dyno tuned a few weeks ago and i only made 240 to the wheels.... i was thinking maybe the cam gear and crake gear might be off a tooth...just trying to find my problem!! maybe its all in my tune...im just pissed cause i spend all this money on the truck and see 15 more horse....soemthings not right! plus the damn truck wont even stay running when you start it up...runs for like 3 seconds then shuts off....i just have to feather the pedel for about 15 seconds then it will run fine.....also it idels at about 675 then it will drop down to 300 then it jumps back up to 675....and its all in a pattern... nothing ever works out for me!!

 

Its your tune, once tuned properly you shouldnt have that idling problem.

 

yea i know the idle problem is in the tune....but i jsut dont see why im not getting the power i should be seeing.....wish i lived in texas so that i could have nelson tune it and be done with it!

 

im just pissed cause im at 240 to the wheels and others with same set up are 340...i know i cant be loosing close to 100 horse dure to having 5" bigger tires....

 

tires being way out of balance could be a small portion of it, but the BFG a/t's balance well even after wear.

im positive it's your tune. i think you had a thread the other day about it, you were runnin somethin crazy like 17.5 afr? that coulda fucked somethin up right there.

 

Yes That Was Mine.....i Was Running 17.5 When I Arived At The Dyno Butafter The Tune It Was A 13.1 Afr..... Guurrrrrrrrrrrrr

 

what kind of timming was it running? i agree its the tune. one tooth on the cam gear is 8*'s either positive or negative. one tooth on the crank is 16*'s
