That's awsom! This started because I don't think my secondaries are opening, I don't hear it and feels like a straight slow pull. I was told that intake is mentioned for drag at high rpm. It's not creating vacuumed at lower rpm. Does that sound right to you - - - Updated - - -

Thanks beekeeper, I have a extreme energy cam that's rated 1800 to 6000 rpm but a weiand high rise intake that's 2700 to 7700 rpm . Just a street performance is all I'm after. Planning on an edelbrock performer and started thinking maybe change heads at the same time. Or just get mine ported and...

Can anyone tell me if I can swap 383 or 440 heads/intake manifold on a 400 and if that would help the performance
