I also have a 4150 nitrous plate that will be going under the carb. I would like a 1" open spacer for hood clearance issues. Does anyone make a spacer like this? Or know where I can buy one?

There are adapter plates available, but from memory they are all around 2". A 1" plate isn't going to be feasible due to the two patterns being so close. Alan Jones

I've done some dyno testing with this shear plate and it works pretty well. For your application you probably want something large like the new Holley 950. Last edited by AndyF; 08/20/13 10:29 PM.

Also, the 4150 nitrous plate is another reason for needing the 4150 bolt pattern. If i buy a different base plate, I also have to buy a 4500 nitrous plate.

I think you have enough material on your manifold to take some alum rod and thread it and install in the 4500 holes then re-drill it to 4150... you can glue the rod in or weld it in... set your 4150 on it to see
