I ma kind of partical to

I have always kind of liked Weiand intakes. The Stealth is the one I am running on my vortec truck a the moment. It is a high-rise & will not fit under some hoods, so that is a consideration. It also is a true isolated runner duel plane. The plenum is divided and the plate rises to the top of the carb base, not like a single plane intake. The Edlebrock intakes seem to have a notch taken out of this divider allowing some transfer of the resonation that sets up in the intake charge between the two sides. Stealth is supposed to be good for 6200 RPM as well. Weiand also makes an air gap intake known as the Air Strike, not sure if it is an isolated runner tho like the Stealth.

I've used both the edelbrock rpm and the Professional Products Crosswind vortec style dual plane hi rise manifolds. They both work great.

I'm sold on professional products, they are some very nice intakes, but there is a knock off of them that just sucks. Make sure if you're buying a Professional Products it is indeed a PP intake and NOT the knock-off

I have come to believe that the RPM and Weiand Stealth are knock-offs of the 1969 302 Z-28 high-rise myself.

Aesthetics in high performance parts have never interested me much. I'd much rather know that the engineering and machining are spot-on. But hey, that's just my opinion.

he edelbrock is its own unique design. The holley 300-36 is a knock off of the GM Z/28 LT-1 high rise.

The proproducts manifold actually makes a bit more power than the edelbrock.
They are not exactly the same. But very close.

I've been using the PP Hurricane Plus on my Vortec headed SBC, It's great for high reving/loose stall. I did however drill & tap a hole into the plenum to run a fitting for the vacuum booster of the power brakes.

I actually just put my PP Crosswind back onto my engine, it's better suited for the heavier truck and I've got the Hurricane plus up on EBay now.

Been running a Ede Victor Jr on this last 355 build, with a few mods. Im running a set of late-model vortec heads, angle milled, big valves, ported runners etc, etc... I tried to build this one on the edge of the street/strip plan, leaning a tad more on the strip side for relaibility & increased HP....Too much C.R., too much cam, not very good street manners, but its sure fun to drive..

Nice intake tho.
