finally combo lining out,new times

Little timing and tuning started to turn good for me.
Had good day at the track.
10.81 at 121.8
1.47 60ft
all steel truck, all pump gas.
Bigger headers helped, just had to figure out what the truck wanted. It likes more rpm.

These ls engines rock.

Re: finally combo lining out,new times

What did you go with for headers.. I'm really thinking it's time for me to swap mine out..

Also, what it the new verter?

You have a recent weight on it?

Headman makes them for our truck. 1 7/8 stepped to 2".
Truck weighs about 3780 with me in it.

I left the same convertor in it.

Re: finally combo lining out,new times
