Alright so after talking to Martin I am now to get -11cc Wiseco pistons and ls3 or lsa heads and have them milled down to 65 cc with the ls9 head gasket that will give me 10.9:1 which is perfect for e85 and boost. I wonder if Wiseco will sell only their pistons and not the whole kit since that is all I need. I found a set of new bare ls3 heads milled down to 64 cc with bronze guides for $589 though. It may cost way more to buy all the necessary stuff to get them assembled than to just buy complete heads though.

Also I am selling my heads for anyone who wants them lol.
Also my supercharger came in. I just need a couple more parts for it to be totally complete and ready for bolt on once my block is built.

So I am considering getting GMPP LS3 CNC'd heads which flow more than 350 cfm at intake and 250 exhaust at. 600. They are only $200 more expensive than new ls3 stock heads. I could (if possible) later have more work done to them if wanted but they seem to flow really nice out of the box. This is as opposed to getting just new stock ls3 heads. On paper which I know is different than how they may actually perform they seem to out flow both the PRC and SD heads and they are cheaper even with adding the BTR .660 springs.

Been there, done it. My ITB set up was just under 9" valley to rail. I cut a good inch plus out of the cowl. Maaaaaybe another 1/2" vertically before I get into glass. You're not going to want to shim more than 1/2" on the K. Will post a pic later if you think it will help in your decision....

So I have priced out the rest of the supercharger parts needed to assemble it totally along with everything else I need to install it in my car and it will be around $2600 but $600 of that is shipping from GMPartsDirect. Trying to see if I can find used parts to source it out cheaper or somewhere with free shipping.

My GMPP CNC LS3 heads arrived. These should provide some really nice power over the 243s. Also I think I am actually going to stick with my original plan of high compression NA. I can get back to 14:1 if I have the heads milled to 63 or 61.5 cc with .030 or .036 head gaskets respectfully, it seems to get 15:1 I'd have to get them milled to 57 or 58 cc and use .036 or .030 head gaskets respectfully. So now I need to find the best intake for the ls3 heads a FAST 102 or a victor with a 4500 elbow? I think I'll do the zl1 supercharger setup on my truck though since it is just placing the supercharger on and switching out the accessories.

Nice! Lol....you change directions more than the wind.
Was really looking forward in how you were gonna pull that blower off. Maybe I have to sell off my ITB set up and give it a try
Get that thing together before the next breeze!!

No I don't have the cam yet.
I am also considering the holley hi-ram intake as well. I am not sure where to go at this point since with the e85 heat soak will be no issue.
