One thing leads to another... mean 318?

I mean either really, that dyno of the 302 vs 327 vs 350 made practically the same hp within 3 hp of each other, engine masters done a 410 vs 367 with 8.5 hp difference, no real sign of stroke adding hp to combos.
That's less then 0.02 hp per cid gain or loss in any direction.
And torque is generally equalled out if everything is geared right.

But the issue here was they used STOCK turd edelbrock heads. The 360 was already at or near maxing the head flow out.
