What willys36 says about plenum volume is correct. Weiand tunnel rams generally have a smaller plenum volume than most other tunnels. The edelbrock street tunnel has a reduced plenum as well. I have used an old edelbrock pro ram manifold in a street application before and it worked well. The rpm range on that manifold was 6500-10,000. It was on a big inch sbc and it worked well. It had a very small plenum and large runners. Take willys36 advice.
