I don't think I'd even bother testing a tunnel ram with a single 4 barrel top. Those look like they are so bad that I wouldn't want to waste my time trying one. I once put a dual plane intake on a race engine just to test it and it almost cost me a bunch of money. The dual plane intake killed 100 hp and the EGT's went nuts. So I learned a lesson there about testing dumb stuff. Don't test dumb stuff unless you're willing to fork over the $10,000 to build a new race engine.
