The RPM Air Gap manifold
I've heard and read a lot about the Air Gap manifold lately. I picked up a new one at the Roadster Show last weekend at a good price and decided to give one a try. Right now, I'm running a Performer RPM and am real curious as to exactly how much better the Air Gap actually will do. After getting the Air Gap home, I was a little bit dissatisfied with the finish job done on it. I will have to do a little port matching before I hang it, lots of cast flashing inside the ports. Did I get a blem? or are all Air Gaps that rough.. Before I take it back I'd like to here from the experts.
My 350 Mouse has early ported and CC'd 461 Fuelers and is a mild door shaker. If every thing else is right, from what I gather, the Air Gap will get me a few more HP up thru the power band, and run a lot better on the street, hot.
