Build the best you can, send it here and I’ll test it.
In fact, the next time I run the engine I’ll put the air hat on it and we can see what the air flow says.
Did you forget the 340 came with an AVS that had a similar flow rating?
And it is apples to apples because like I said, a swap from a 625 to a 750 is a regular occurrence.
I’m not doing an 1850 Holley test because they are door stops at best, right along with the AFB.
