With the 2.41, I'm hoping for mid 30s. I don't know the history of the trans; other than it came out of the donor with 90k miles on it. I got the biggest Derale cooler i could- 13x14" with -6 lines...I love this build, on a more door even! The only thing that would have been cooler would have been a manual. Was it a T5 that came behind the 3800 in the fourth gen Camaro/Firebird? I am really starting to hate GM autos, all they do is leak and die. Then I have many hours of laying on my back and heaving transmissions around. Hopefully your 4L60E doesn't get the weak reverse like mine or the common 3/4 clutch failure. Get this thing running. I am betting it will beat my Dr Olds Mileage Machine in the mpg department.
Getting closerKind of in a holding pattern for a minute- have to see if my daughter's field hockey game gets called for rain. I got this far
