Getting ready for timing and im not sure how much is safe-it still is my dd but never tow and very rarely haul anything . thanks guys

 

I have 16* in mine with no ill effects

 

big diffrence at 16*?

 

Pro:runs smoother lil better top end lower egts better fuel milage
Con:alil harder to start when its cold but it does and will

 

Mine breaks up a bit after 3200 unless its got a good load on it. i was hoping bumping the timing will help clear it up up top.

 

It will help and I'm hoping you have HD valve springs as well... didnt see them listed

 

yes i do. i forgot tolist them

 

i ran 16.5 on my dd and i pull a 5th dump bed alot and drive the **** out of it, egts where around *900 towing 9k and getting up to speed pretty good but my probe was post turbo, after this rebuild im going to be at 18* with 4ks and the probe in the manifold, so we will see how it goes

 

Thanks for the input. Im thinking of going 17* and see where my numbers are and go from there.

 

Don't go more than 17 without head studs, heck with that turbo you probably need them if its even lighting.

I ran 19 on my truck before the rebuild with 370's. Pattern on the pistons actually looked really good. On the new pistons I am at 22* right now. No side effects what so ever.
