Rectangular to Cathedral adapter?
That was my original inspiration behind getting the Mast Small Bore LS3 heads.... Build a C5 ZR1/Z06 killer.

So next would be how do we affordably /drive/ said blowers? Seems like most of the threads I have seen stall(and often end up in sale of a lot of tempting parts) when they get to the accessory drive(s) to run the thing.
What I'm saying is there are a thousand cheap blowers out there and no accessory drives I've seen for sale for a price as reasonable as the blowers. I did the math and ended up in used Magnusson/Whipple land. At that point, are these actually a bargain?
I don't mean to come across as negative. I want one of these on my engine bad. I've been drooling over the blowers but it never looks affordable as a complete solution. To me. And I'm not that smart, hence why I'm asking you guys.

Thanks!
I will start another thread so you can get back to your (very nice looking) adapter plates.Now I want to see this in a budget compound-boost 5.3 application.
What is the implication, if anything, of the increased volume of the adapter? Are we increasing the volume of the head intake ports, the length/volume of the intake manifold runner, both? Am I asking a question that doesn't matter?
Thanks.
Heres a final design spacer, and a 4.8 running the LSA blower with a truck drive (but no power steering)
These are patent pending, and im not showing a 100% complete set unless you buy a set, or the patent is finalized.
425 shipped in lower 48
uses stock gaskets on head side
uses stock gasket on blower side
bolts supplied
raises blower by an inch
Nice fix... Freaking good idea, and they look great.
And patents are powerful, so what if a guy at home makes a set, it's the corporations who try to sell, that would get a suit on them.
And 400 ish, is kinda expensive, but it is what it is, because patents are very expensive. In the future if you can make a run of these, hope the price can come down.
I would advertise on eBay.
Cool idea my friend.
