Wow! Just stumbled on this thread. I love what you’ve done here. I’ve thought about fabbing a manifold almost exactly the way you’ve done it. I made one for my 302 with rectangular tube and tube elbows for 2 DGV Weber’s and always regretted not making it for 3 . Splitting and stretching one end of 90 bend is exactly what I thought of doing but you beat me to it. I’m really glad to hear that it performs well throughout the rpm range especially low end. What are you running in the way of cam, drive train, rear ratio and such? I was originally going to put mine in an AD truck but now it’s going in a 48 Chevy 4 door.
