Intake manifold options for a Magnum 5.9/360

I had Mike at B3 racing drill the indy intake for LA bolt pattern. He is the one I got the heads,prw rocker arms and Smith brother push rods from. Also I found a guy wanting to sell the magnum indy intake that was needing money. So I bought it brand new for $350 shipped. Of course that was 7 years ago. Damn parts have went up in proce$$$ a lot sense then. Lol
That’s pretty cool in my book.
What does the converter stall at?

Nice price on the Indy intake though I think it’s out of Kerndogs parameters. I generally will lay on wait to snipe a part inexpensively. It’s the only way I can get it done really. Even more so with current conditions.
