Yes the performer will be a small upgrade, the biggest difference is the weight.
I totally disagree. The Performer has a more balanced runner design as well as a much larger plenum vs the stocker. It's value is not just in the weight savings but in the double digit added hp/tq as well.
are you talking about the Performer or the Performer RPM? the RPM is a higher rise intake which might cause hood clearance issues - the regular Performer is essentially stock height or maybe just a fraction higher, no problem with drop base air cleaner.
I have the Performer on my 350, absolutely a great upgrade over stock.

The regular Performer intake. I'm not a high RPM guy, want the torque...
The reason I ask is that the Edelbrock page says it won't work. Any suggestions for a drop base air cleaner?
In the interest of preventing truth decay, THIS is a "442 hood" for 1970 (and do you know how hard it is to find a photo of a 442 with the original metal hood on Google Images?):
I assume the OP means the optional W-25 O.A.I. hood, as now seen on EVERY SINGLE 1970-72 Faux Four Two on the road...

Yes, that is what I mean. Sorry for misrepresenting and I throw myself on my knees to the floor and ask mercy from the court!!! LOL
So, with my Faux 442 hood, will the performer fit and what drop air cleaner is recommended?
drop base height suggestions probably range .75" to 1.25" depending on your air cleaner element and carb height. Mostly a trial/error thing unless somebody who's already got your exact setup can clarify further.
I have a 1.25" drop base with 3" air cleaner element and even with a 1/4" carb spacer under the Qjet it clears my stock-height hood. But that's on a 350.

That's an apples to watermelons comparison, sorry. Same with the SB Performer vs the BB Performer comparison.
You'll need to make some mods to either the intake or the air cleaner base. But imo it'll be well worth it.

The factory W-30 intake is a clone of the stock iron intake. The Performer has different runner geometry. It's not a massive difference, but it is different. Biggest difference is the "T" intersections in the runners, as is obvious in these photos. Not the best for flow.
W-30 (stock iron is the same shape):

70sgeek is talking about an SBO Performer (sans "RPM"). The OP is asking about a BBO. Again, while true (about the SBO Performer) this post is both irrelevant to this thread and obviously confusing to the issue. As the photos above show, the BBO Performer IS taller than stock.

Check the Edelbrock website, the Performer is not close to the height of the stock manifold.
correct, which is why I qualified my fitment details were for my 350. I figured there'd be differences in deck height at least between SBO and BBO but the variables are essentially the same - carb, base height differences, air cleaner height, accessory items, etc.

Huh? Not by a long shot, sorry. The regular SB Performer isn't much taller than a stock iron SB intake. Whereas the bb performer is noticeably higher than stocker. Just one of a few differences.
