this may seem a silly question but.........

Is there a difference in timing between a 1 barrel 225 and a 2 barrel super six?

I have swapped to the super six setup.
Any tips or hints would be greatly accepted.

An increase in CFM alone should not have a major impact on timing but now that you have more CFM the engine can rev higher and that could lead to over advanced spark timing.

Now is the time to check your spark advance and recurve the distributor to match you engine combination and driving conditions.

thank you for the response.
