Hi all,

I have been playing around with the gas setup on my 351c. Changing from single to twin 425's. My current setup is still using a single converter (B2) to feed both 425's.

There is a lot of talk about using dedicated converter/mixer combos. By adding a second converter would i expect to see a significant difference.

And what is the max HP i can expect from 6mm supply line.

Thanks

A single B2 is good for up to about 300hp.
6mm line may be alright up to 200hp, but my old Crossflow never liked the 6mm line.
Replace it with an 8mm line minimum or a 3/8 flex line.
