We would have defeated the Soviets. It would have been costly.
In terms of production we would outproduce the Soviets in any capacity imaginable.
Consider trucks. If you watch AHC or any documentary on the Eastern front you will see the Soviets riding along in our trucks. They only made about 125k for the war. We produced in excess of 2,000,000 trucks, jeeps, etc.
We doubled their production in planes.
We would have shifted the steel being used for the Navy to the airforce and army.
We would have either upgraded and/or replaced the Sherman with Pershings or something better.
Israel showed the Sherman, while upgraded, could defeat the T-54/55 in 1956 and 1967. Where there's a will there's a way. Though we would have had the same solution to solve in fighting Germany. We kept the Sherman production line going as we found it was easier to ship two medium tanks v one heavy tank.
Someone else has already noted we pretty much fed Ivan. Take away the food and Ivan gets hungry.
Air power was the decisive element of WWII. We excelled in this in terms of long range bombers and fighters.
So from a purely production standpoint we would beat the Soviets. They simply could not keep up with us in that capacity.

We had gone into Russia in 1918/19 to intervene in the Russian Civil War and it proved wildly unpopular at home.
Wilson was forced to withdraw our troops in 1919.
