Default Is an OS 70 (4S) big enough for a DPM ultimate 40?

Is an O.S. 70 4 stroke big enough for a Dave Patrick Ultimate 40?????
I have not received mine (backorder) yet but am getting ready to purchase the engine.
I already have an OS 70 in the shop without a home but if it's not gonna pull it around I am prepared to make a bigger purchase.
(I fly at sea level and want unlimited performance)

Absolutely. A pal has one with a YS 63, which is a comparable engine. He has unlimited vertical with a 14x4 prop.

The 70 Surpass is plenty of motor for this model.
