If I retorque my factory head bolts tighter how much timing could I run then?

The most I plan on towing is 5 thousand lbs of race car and trailer combined and that is once a year.

 

not much. ive been at 17* for awhile now on stock bolts, keep it in the 16-17 range.

 

That would depend greatly on how much fuel u got turned to it as well as how much boost it's getting. The other thing is, how many rpm Ur turning will affect how much timing will even do u any good.

 

I am waiting on my dv socket to show up along with the rest of 60lb valve springs. I want to run it as high as I can with a stock bottom end and balancer or when the truck starts to defuel. So whatever timing would match the 4k gsk, afc mods, 100 plate, rotated barrels, 4.10s. I have been looking around online and there are some people getting up into the 18-21* range on stock bolts/gasket. I do live in Alaska where it gets 25* below zero sometimes so I don't want to make it to difficult to start. I do have my block heater and grid heater.

I've hit 42 psi with my wh1c. I think the wastegate is stuck. I plan on doing a little gring on the divider on the exhaust housing.

But I can bury the needle on my 1500* degree pyro which is mounted pre turbo. It buries it the quickest in gears 1-3 it's a little slower when od and lockup are engaged. So I'm thinking I need to slide the plate back a little
