Just wanted to know if there is anyone out there running any other intake besides the edelbrock Performer that fits under the stock hood on a 72. From what I understand there are not many options to choose from. Just wondering if anything else works.
Thanks Rodney

I have an Edlebrock Dual Air Gap in a 1975  wit a 383 and with a stock hood. I have a Quick Feul 750Q, a recessed lower airfilter plate around carb and a 2 1/5" air cleaner. I tried the 3" air filter and got a slight bit of interference. I have no hood insulation so that may help. One day I will try the 3" air filter again and get some silly putty on top of the circumference of the air cleaner to see esactly how much clearance I have at each location.

For whatever it's worth, I have a Cyclone Plus dual plane intake, a Holley Street Avenger 770-cfm carb, and a 3-inch air filter on my L-48, 350 in my '80.  I also have no insulation on my hood and I have no interference.

Us guys with the later cars won't normally have the same hood interference issues as the earlier('68-'72) cars. The hoods on the later cars were a little taller in the center anyway. Especially the '73-'76 cars with the cowl induction hoods.
The earlier cars with the big block/LT1 hoods did have a little more clearance than the "normal" hoods, but not a lot.
One big problem with the earlier hoods, and taller air cleaners/intakes is the stud/wingut for the air cleaner poking a hole in the hood...

From what I know on mine I have about 1/2 inch from the wing nut to the hood..I think the Performer 2101 is the same hieght as the stock intake is..I checked it out when I got a new bolt and wing nut that had GM written on it.. don't tell Ethan that his play dough worked real good for this!!  oh and if you use play dough to check it put a little flour on it so it doesn't stick to everything!

Gotta take into account that the engine is gonna torque up when you step on the gas, too. 1/2" might be just enough!

Rodney,

There are many available that will fit under the stock hood.  Most websites, Edelbrock, Weiand, Trick Flow and others, give the A+B=Average height numbers for their manifolds.  See the photo below I got from the Edelbrock website.  The stock on my 79 L-82 was A= 3.75.  B= 4.75 = average 4.25.  According to the Edelbrock website the Performer 2701 is A= 3.74. B= 4.80 = Average 4.27 which means it is only .02 inches taller than the stock.  Here are a couple other possibilities that will fit with a different air cleaner.

EB Perf RPM 7101

4.2

5.25

4.725

EB RPM AG 7501

4.2

5.25

4.725

I hope this helps.  Bill

Many folks thought that the Airgap was a taller manifold than the RPM. I have the Airgap - love it!!

Years ago, I helped a friend paint his '72 with House of Color Candy Red.  He then built a 383 for it.  A few days before the biggest drag race weekend of the year, we were "testing" on the country roads, when there was a BANG.  I looked in the rearview mirror and saw engine parts bouncing in the road.  We towed the car home and scrambled to pull the tunnel-rammed small block from my pro-street car.  After a couple days of welding adapters of every sort, we were done except for the hood.  We found a servicable small block hood, used the sawsall, and painted it flat black.  We had a great weekend of racing, after which my daughter announced we were leaving the engine in for a few weeks so she could drive, too.  She was quite the hot-rodder, but had never driven a stick.  So we trailered the car to the industrial park where I worked and spent a few hours doing full passes down the streets.  Eventually the police came and told us to stop.  When we went to the next drag weekend, she was having so much fun she forgot to look at the tach.  It was an engine you shifted at 8,800 RPM, and she over-revved it!  I have it on video.  The sound turned into just a screech as it went past 9,000 RPM.  It only had one spun rod bearing.  A little fixing, and it was good as new.  That engine went into several cars over the years, and finally met it's end in a sand rail in Las Vegas.

Larry, I often think about some fiberglass creativity (a la motion) for the stock 79 hood on the side of my shed!! Wink
