It is hard for me to believe but it has been over a year since I put the Whipple charged 5.3 in my '94 work truck. 18,000 miles and 3 4l60 trannys later I must say that this is the best combo I have ever had in this truck. The 5.3 is so much smoother than the previous motor (an LT1).

Last week I finished a 4l80e conversion on it so I am pretty sure my trans problems are now over !

The only problems I have had with it is a leaky A/C fitting (my fault) the trans woes, and I had a fuel pump go out (it was a few years old-was in there with the LT1)

Long live the LS1 style motors !!!!!
