I'm Cummins swapping a '74 Duster, thought I'd share the progress.

BOLDERDASH...
I welded all that c*** in there.Frame connectors so forth, homemade frame connectors I should say, I'd never paid hundreds of dollars for a straight piece of metal I have to weld in...
Cheap harbor freight flux wire welder...
It's not like the body is going to twist like a big pretzel, it's just going to stop the slight movements...
After years of drag racing with a four speed and slicks, I can still go out there and my welds are just fine...
People like to overthink stuff like they're racing a ten thousand horsepower drag machine... they're not...
With the budget and time given, what kind of horsepower do you think this guy's going to make..?..
Likely all that welding and frame stiffening's only going to gain someone with modest horsepower next to nothing...
for starters why are you responding like i was even addressing you, what you have or have not done has nothing to do with my statement. Secondly he stated he has little to no welding experience. And if you have any experience with welding you will know welding a very thick gauge chassis connector to a most likely pitted a body floor is difficult. If you bothered to read he has stated he has purchased chassis connectors from USCT in a non standard even thicker grade.
He will make at least 600hp and will have massive torque. It will also be equivalent of three large men heavier than the standard duster set up. So yes he will need plenty of stiffening, but that stiffening is no good with cocky **** welds.
