anyone tried gmpp new dual plane in comparison w vic jr for a street setup?

 

Sure it would be like comparing the Performer RPM to a Vic Jr.

 

thats what i was thinking. in other work a much better street intake. now if i could find someone to swap my vic jr for their gmpp dual plane.

 

The dual plane is way,way overpriced.Just be patient.As soon as another company releases one G.M will drop the price to be competitive.They are over $500 last time I checked....$275 for a performer R.P.M for a regular small block.

 

i think sdp has them for 469.00 . still really high. patience...patience

 

I will wait until they are at $300 or less.The intake is the last to go on.If you are building a street motor check out the dual plane L.S motor in the engine masters challenge.Small cam,L-92 heads and over 500 h.p.Big torque down low where you need it(on the street)..

 

I'm wondering if anyone has actually measured the dual plane for carb height? I presently have the open plenum GM #25534401.

These pics give the general idea regarding height.

Shows intake height in relation to truck bracket alternator height

 

Looks just as high as jr

 

Wow. That might be the tallest dual plane ever.

 

thats a wicked looking intake.....figuring out y it cost so much....must be 50lbs of aluminum in that thing !

 

That's exactly what I was thinking when I came to your post.
