Thor #227 was published at around the same time as 
Fantastic Four #150 and had the same creative team, Gerry Conway and Rich Buckler.  As mentioned, like his 
FF run Buckler's
 1974
 Thor run relied 
heavily on Kirby swipes.  Here, #227 Thor's details are clearly based on the well-known Thunder God splash in 
Thor #124.
But I think there was another Kirby page used as a model here too. Take a look at the positioning of the background figures and the curved shape of the Torch's and Thor's torsos--these point me to this 
Fantastic Four #89 splash.
