I got to thinkin a bit and was wonderin how much of a difference i would get if i did a 6.0(LQ9) swap then a 5.3. I did some lookin on the DTL and found some info but it didn't help enough. So what would the power/trq difference be from a
6.0 LQ9(prolly with a 4L80e)
Full Bolt on
and 226~ cam

then a
5.3
Full bolt on
and 222~ cam
?

 

look up AP2002. he had both combo's you just mentioned and picked up around 6/10 in the quarter with the 6.0 with a 226 cam. it runs mid 12's all day in a extended cab silverado

 

i have a 4.8 right now and im going 6.0 in about 2 weeks... even if it was a 5.3 i would

 

see sig... 7tenth's difference....

I got a built 4l60e..

 

what were your 60' times with the 5.3?

 

Okay, I think im going to go with a 6.0 later on. itll be hard doin it atm so ill just stick to boltons and tranny/rear end things atm.
