I thought I saw a thread on here with dimension for making them. I have searched but didn't find anything. Does anybody have the thickness they need to be to bolt a 215 intake to 300. I know the ports are smaller. But I have a rover gems intake that I think I might try and use with terminator x EFI. I was gonna use a sniper but I don't have a 4 barrel intake. So I would have to get one of those then I would have to buy an adapter to mount the sniper. This is not a project that would be happening soon. But in the end I would like efi the hyper spark distributer to control timing and a small pair of T3 turbos mounted on flipper rover stainless manifolds. As always thanks to everyone for your help.
I believe Dallas Brown had something on one of his video posts. https://www.v8buick.com/index.php?posts/3247859/
