Went to get arbys awhile ago and punched it at 40 (2nd gear) and the speedo jumped to 80.

The road was pretty smooth, so I'll have to try it again on a better road and see if I get the same results.

These tires weren't mean for this much power hahahah

 

where is the heater core on our trucks? i've done like 3 or 4 of them on various GM vehicles & i've NEVER had to remove the entire top of the dash...bottom yes but never the top

 

GM decided to make the only access point to the heater core on the top of the dash area.

You have to take everything loose and pull back the passenger side as much as possible, you have to un bolt the whole HVAC system from the firewall (its a bitch), and pull that back, and then BARELY slide the new core in.

Should've taken more pictures, but there is really no easy way to do it.

 

dude I can fart with more power than you put to the ground...


now thats sig worthy right there

 

The DA around the time of your post was -800 , where is a track when you need it

 

they hardly ever spun with me. i guess having that big *** converter helps you do that.

 

Dont you just press the cycle air button when the AC is off and it stops blowing?

 

Nope, those buttons are unresponsive unless the AC is on. There is no way to stop cold air from getting in if your heater core is bad. The best thing I could do is put it on the defrost setting so it blew on the windshield, but it still gets really cold.

 

Pull out the air vents and stuff them with newspaper
My center vent(the one you can't stop the air from coming out of) is like that since my AC actuator is bad

 

Well, with it set to defrost, your A/C was running automatically.

I turned off the bullshit auto recirculate in my tune.
