Another thing I just thought about is the oil pan. I am guessing with a 4.125 stroke I am either going to need to machine the oil pan for clearance or get an aftermarket one that is made to fit. In addition to clearance should I run more than 6qts with this size stroke especially if I get a larger oil pan?

No, oil level is unchanged. It will be more sensitive to overfilling because the crank throw is longer. You will need some sort of improved PCV system, the stock venting will not keep up with a 4.125 stroke and it will pressurize the bottom end/push oil. I recommend either -10 vents from each valve cover to a catch can (or cans) or a vacuum pump setup.
Also I have 850cc injectors in my car and theyre at roughly 70% duty cycle so your 95s will probably be fine, as long as you can get them to idle.

Does anyone sell a 4" y pipe? The only thing I could find close was a 3.5" to 4" y pipe which would mate fine with the Kooks with 2" primaries and 3.5" header collector that I was looking at. True duals would probably be better though.

Flowmaster makes a merge, mufflex makes a y pipe with the flowmaster merge to fit standard LS1 type headers. I've seen a few cars with this setup and its pretty effective for as simple as it is.

I think ARH will make their Y with a 4" merge if you ask as well.
True duals would be the optimal way to go.
Mast makes a 4.125 clearance stroker windage tray for 4th gen F-bodies, it is the one that isn't full length.

A question to those using E85 already, I am curious do you have to upgrade the fuel lines as well with PTFE braided stainless steel lines? I was eventually going to do this anyways but I want to know if it is absolutely required or not.

Btw I ordered my ARP main cap studs, after those are in all that I am waiting for are my Pistons to be made by Wiseco and arrive here and then off to the engine shop it all goes. I still need to find a respectable engine builder in VA no further than Roanoke from Northern VA otherwise I'll just drive down to Tick Performance and drop it all off. VA Speed won't do shortblocks only longblocks but I don't need them to do a longblock so they are off the list.

PTFE isn't "necessary" but for the slightly added cost (fittings are a little extra too), there are multiple benefits.
