I think what everyone is trying to say to you is.
With that stall speed your truck is going to be almost unusable. If you’re going to drive it like a daily driver, you must address that stall speed issue.
Get it back down into the range where you can use it
Which is going to mean changing to a more useable cam profile.
7K on the street? WOW! Around here, you’re going to attract a ton of unwanted attention from law enforcement.
That truck will be no fun when it’s sitting in the impound yard. And, that’s not even talking about that high stall converter’s life expectancy. By trying to drive it outside of its “built for” stall speed, it’s not going to live very long. And its performance is going to be sub-par.
A 1000 rpm stall converter is going to be way closer to what you want for the street, even it will be clunky on the street.
Cam the engine so the power starts building straight off idle, to about 3500rpm max.
Gear that axle to 3.73. You can keep the tires. With the power you’ll build at that rpm range, it’ll turn those meats just fine.
That little blower could be really cool on the street , but, you’ve got to get the rest of the parts to work with it.
Otherwise, it’s just a lawn ornament.
Ask me how I know about lawn ornaments…
