hey guys i just put a stock 1998 ls1 cam in my truck i got for free from a friend and figured it would be a learning experiance. I didn't change the tune but need to as this cam wants to rev a lil higher then the old one.

old times at night 40 degrees out
2.292
6.340
9.657
74.148
12.424

14.935
91.84


New times with same tune and ls1 cam in the day about 60 outside and head wind

2.2811
6.357
9.684
74.45
12.432

14.908
93.32

the truck feels like it pulls better in the top of the gears but it is dead out of the hole deffinetly not traction problems just a pig. I know i need a converter but what size? I tow my car to the track but still want a decsent stall
