How much timing is safe for a dd
#11
back in the day when a 12v was brought to a dealer running poor, standard thing to do was to bump the timing up to 16*. I would suggest torquing down the stock head bolts alittle tighter, and I would bump it up to about 18* and not even think twice. 2 or 3 years ago on my puller I ran stock head gasket and bolts, that I torqued up, in the 2.6 class running over 50 psi and 21.5* timing. Biggest thing is to let the truck warm up before you get on it.

check your fuel pressure to turn higher rpm with that pump fuel pressure is your friend. When my 94 was my dd with the 175 p pump stock head bolts and a sliver bullet I ran 22.5*

thanks for the input guys. I already torqued the stockers down to 120 im not planning on it staying together forever but so far so good. making 45 psi with the hx 40. i will check the pressure for the stuble up high too. So my next ? with all that timing, like around 20* do they still start when its cold? im all the way north in jersey its like 5* out rite now
