Cant remeber exactly but werent the allison engines unsuitable because they

Saw a photo yesterday of a WWII B-17 test aircraft powered
with four Allison inline engines as opposed to the usual
Wright Cyclones.

Understand the modification added about 800 hp to the
aircraft.

Anyone know why the modification didn't go anywhere?
The usual suspects? Too much disruption to B-17
production? Engines needed by P-38, P-39, P-40?

Sorta "Lanc looking".
