I know that many of you here have high HP Ys with superchargers, and that for the most part, boost is the same whether it comes from Centrifigal or Roots superchargers or Turbochargers.  The principals are the same, just the methods of delivery, and the amounts of boost differ.  Where I run into snags with my research and planning, is what durations do I need to use as a baseline for my Twin Turbo Y project?  I don't really want to spend a lot of money changing camshafts, plus the work involved in that, so it boils down to that I want it to be a one or two shot deal, with figuring the best camshaft profile to make the most power out of what I will have.  Currently, I have a deal cooking with Glen to snatch a 292 block, go .050, and then either use a 292 steel forging, or a 312 crank.  Still pondering the cylinder head issue, have a set of `57 G heads, but would like some of the 113(is that correct?), lower compression `58 heads, or even the `61-`62 heads.  I plan on taking baby steps with the boost, starting at around 6 or so lbs of boost.  Yes, I plan to get the Probe forged pistons from Mummert, prob have to cut down the domes.  I need to keep compression around 8 or 8.5:1, since I eventually want to lean on the boost a bit.  My intention is to use the Blue Thunder or even the `57 intake, but, I may fabricate an intake for 1 4V carb, again, still pondering and researching airflow.  Probably have some work done to the heads, including 2.02 intakes, but will run many iterations in my software before I buy too much or pick up any tools to see what I need to make what I want. 

I know I will have to throw out most of what I know about building out to do this, since my experience is all with 302, 351W & C, 390 and 460.  390 is probably as close to the Y as I have ever gotten, but even they are like night and day difference from my 292 project. 

Some of my many questions about this may be answered in the new book I just bought, if and when it gets here, lol.  One of my main concerns is oiling, especially the rockers and lower end.  Is this something I need to pay extra attention to?  My dad warned me about the rocker trouble,  so I am at least aware of it.  What about balancing?  Is that a particular chore on the Y?  I hate to sound like such a newbie, but the Y was discontinued about 3 or 4 years before I was even born, so I havent had that much exposure to it.  I do appreciate the help you guys have already given me, and the encouragement to break away from the norm.  I guess, I just dont want to look like a novice when it hits the road for the first time, you know...Thanks in advance for any and all help.....
