Copo...
I started with a hot rod 292 in my GMC, like you I wanted something simple to bolt - well not quite bolt in.
After getting 16 MPG and lukewarm performance with it, I was wishing for a bit more. The next iteration was a stock '05 4200 with a 4L60E ... what a difference. 24 mpg and an extra 75HP.
Now when I open the hood a crowd gather and ask what is it?....
If I had a dollar each time that asked I good get the truck painted.
