Filling Crossover

[BruceSki]

What do you guys use to fill it in and where can I buy some.

Going to do this to a stock intake mani on a 62T 61x with stock 38's. Single fuel pump.

 

[BruceSki]

anybody there?

You can use Devcon aluminum liquid or JB-Weld.

How much do I need?

Two of the little tubes of JB, I would guess, the crossover really isn't that big

Another related question, if you don't mind motoman... Do you need to run the plate between the reeds and manifold if you have a filled crossover?

whats the gain from filling crossover with stock carbs

 

[BruceSki]

I believe its just increased carb signal. You don't lose the signal through the crossover. When one piston is sucking in a fresh fuel/air charge it will only pull through that cylinder's carb instead of sucking through both. It allows for more precise carb metering, and a bit easier tuning.

I don't believe so

I was wondering about this. Glad someone asked it.

 

[BruceSki]

so whats the consensus on running the plate? is it required or not?

 

[BombThreat]

if the crossover is filled and made completely flush with the intake then there isnt any need for the plate.
