Converter and gear swap.

I'm planning on running the current 3.55 setup I have for street use. I am going to be putting together a 4.56 spool setup for strip use.

I have already talked with Kenny at PTC and he said he could put together a converter that will work with both. Obviously it will be tighter on the 4.56 if set up for the 3.55's, and I understand that going in.

Here's my question.

Does anyone here have a similar setup?

How does it perform with the numerically higher gear?
