New carbs??..

You can buy two ProForm 750 double pumpers pretty economically if you look.

If you talk real nice to me, I can make you a smoking deal on some brand new TR linkage I have.

Then you'd be set.
I thought you were going to advocate for the 750 carbs instead of the 625's?..
The one right up where they're using a 409 Ford they put the 625 carbs on then they needed more manifold then they put more manifold. On then they needed more carb in the 750s did the track on top of a tunnel ram for max horsepower...
Just another $65 for the two...
