I am in the process of cleaning up my motor and painting it. I want to change intake manifolds. I have a carb 502. I am upgrading to Stainless Marine exhaust also. I have narrowed it down to 2 manifolds. Can't decide which is better for me.
It is between the Edlebrock RPM Air Gap or the Edlebrock Performer RPM series. Which would you use. Any benefits of using either.

Thanks!

I'm not familiar with the air gap but am running thr rpm performer and have had great luck with it! It makes great power to 5200 and thats where I wanted to be. I tryed a merlin single plane and didnt like it. The power came on to high in the curve for me...I think DanB is running an Air Gap on his 540 you might want to send him a PM....

I am running the RPM intakes also, they work great for me...Fred

I have 2 to sell

I run raw water cooling in saltwater and opted for the Merlin Marine intake due to it's bronze water passage inserts. (I also have a high compression/radical motor)

Doug,

Which ones do you have and what is your $$$. What kind of shape are they in? How old?

I used Wieand Stealth's on my built carb 502's and was very very happy with the performance. Made more torque than the darts I had on there.

I also use the weiand Stealth on an otherwise stock 454. Good power throughout the rev range.

I have a Air Gap intake for sale $150
