My stock conv is about 1800, if i use a Trail Blazer conv, can i get
2000-2200 out of it ? just want a few more RPM's. I was told this
is a decent swap for what i am looking for. just double checking
out the info. conv is free.

 

Yup it if it came out of a 4.2L trailblazer you can get a good bit out of it. Some guys claim to flash it to 3000rpm behind the right builds.

 

Is this a straight bolt in swap for a 4L60 W/5.3 ?

 

yes straight bolt in. I heard a stall of 2500 is average
