Hey all, currently have a cuda dual scoop hood (nostrils some call it) and have been fighting the limitations of raising my 950 proform carb. I'm currently running an indy dual plane manifold with a drop base air cleaner. I've shaved the top of the nut for the cleaner off and managed at present to get a 1/2" spacer under the carb and still get the hood to shut. I'm acquiring a standard flat barracuda hood that has beed modified with a 4" glass scoop fitted so looking for advice on possible other intakes or biggest spacer I can get to work for more power. Motor is 440 with indy EZ heads. A weiland tunnel ram with dual carbs would be great but I know I am dreaming.

I have the longer throttle cable required.
Thanks
