In my opinion, yes. Most carburetor manufacturers have a rule of thumb that says vacuum secondaries with a stall under 3000 r's, double pumper with a stall 3000 or over. I don't know what converter you're using, but the 750 will work with anything close to that in my opinion.

The stall ratings are an estimate- lotsa variables as you know- but Hughes makes good converters, AFAIK.

When you get your engine dialed in and tuned right, you will likely see the stall is much closer than it is now!

Yeah. That combo is WAY down on torque compared to the creature you're putting together now.

Yer in for some fun, now!

are you using a roller cam? if not, you don't need a wear plate or a button.

And
if you are using a roller cam, then you need to check the endplay of the button to the timing chain cover. furthermore, a regular timing chain cover isn't really stiff enough to hold a roller cam in place
