Cabo, SBC Intake Manifold & Chevy Enthusiast - CHP Garage


Jan 1, 2009

And The Winner Is
Hope you had a good time in Cabo! Did you go to The Office? You mentioned wanting to see some odd sightings while out on trips and I think I've got one for you. Last May the better half and I went to the Mayan Riviera, south of Cancun, for our vacation. We went on a tour where we snorkeled in a cenote (a cave system filled with the clearest, freshest water I've ever seen!), snorkeled with giant sea turtles, and went on a zip-line excursion. At the zip line, after being fitted with harnesses, we were escorted to what was called our "limousine." As this thing...err, sputtered up to where we were standing, I couldn't stop laughing and had to get a picture! Our guide said, "Let me take your picture in our limo." We rode down a dirt road to the platform for the zip, which ran about 800 feet through the jungle, starting at 30 feet up and ending about 10 feet high-mucho fun. At the end of the zip line, our trusty limo was there to take us back up. I couldn't help but watch the shocks and control arms as they flopped around, bushingless, over the bumps on the dirt road! I came to the conclusion that our "limo" started its hard life as a Chevy truck. What do you think?

As we returned, another group of tourists was loaded into a "deluxe" limo, one with an awning straight from a house installed to cover the tourists!

All in all, we had a great time and I noticed something interesting. All the newer Chevrolets down there were badged "Chevy," not "Chevrolet"!

Okay, quite honestly, I can't believe the number of responses we got to the question I posed back in the Nov. '08 issue. I had hinted at where I may have gone for a little getaway, and while many readers came close by simply guessing Baja, Brian was the first official letter to come through with the city of Cabo. Congratulations, Brian, and expect a few goodies to come your way in the mail. And yes, we definitely checked out The Office and what a blast that was!

For those of you who took the time to write and included your address, I've already placed your letters on my desk and I'll be sending you a sticker or two! - HD

Manifold Shuffle
Thanks from every Chevy small-block lover in the world for your article on intake manifolds ("Manifold Learning," Sept. '08). You really cut out all the guessing I had with the dual-planes. I guess you can't go wrong with any of the newer intakes. The 4 hp and 14 lb-ft difference of torque spread figures were so close that personal preference really won't let anyone make a mistake. Next, how about an article on multiple sets of headers (on a Chevelle, of course)?

I actually have two comments. First, I was just reading the article about the 16 SBC intake manifolds in the Sept. '08 issue, page 23, where John Nelson wrote, "...while we're at it, we could see just how much power the RPM Air-Gap can support." Wow, would I like to see this! I had a 383 with an Air-Gap on it, and it was awesome. I'm currently building a 408ci small-block 11.5:1 compression with Dart 230cc Pro 1 cylinder heads, a camshaft with 255/262 duration at 0.050 with 0.630/0.630 lift on the intake and exhaust. I'm wondering if I should use the Air-Gap again.

For my second comment, I also read in the same issue that you're debating between an LS and a conventional 383 powerplant the Project '73 Camaro. I say go with the LS! I am really tired of 383s now, and let's face it: They are the new 350. Another option I would love to see is a big-inch 408ci, 415ci, or 421ci. Do something different! 383s are so 10 minutes ago.

I just want to congratulate you on your "Manifold Learning" article in the September issue. It was the best tech article I have read in a long time. It provided valuable info to the Chevy enthusiast who is always looking to improve performance. My hat's off to John Nelson, who did a great job on this project.

I would like to encourage you guys to follow up this great article with one called "Header Learning." Longtime Chevy enthusiasts like me would like to know how the tri-Y headers match up with the long-tube and shorty headers. Also, use the same 383 mule with the same two cams as in your "Manifold Learning" article. Every Chevy enthusiast will be drooling.

Calling All Young Guns
It's a Chevy High tradition to celebrate youthful passion for our hobby by setting aside a bit of space each month to spotlight a Young Gun, which we define as high-performance Chevy owners who are 25 years of age and younger. Going forward, we intend to keep highlighting youthful fans of Chevy power by setting aside once space in our Rides section each month for you crazy kids and your cool Chevys. Whether it's new, old, or a work in progress, we want to see it! All we need is for you youngsters out there to write in and tell us all about it. Send your prints and hi-res photos to Young Guns, Chevy High Performance Magazine, 6420 Wilshire Blvd., Los Angeles, CA 90048 or email with "Young Guns" in the subject line. Photos must be able to run 300 dpi at 5 x 7 inches-in other words, use your cameras best setting.

The past couple of weeks have been somewhat out of the ordinary, in a split personality kind of way. As usual I had the same quagmire of stories and blogs to trudge through, and trudging was the best I could manage, unfortunately. On the other hand, two of the projects I worked on blasted through my daily funk with either brute horsepower or sheer speed-the perfect antidote to the blahs.

The first of these was the Whipple supercharger story in this issue-no doubt you read it before you made it to my back-of-the-book rant. The thing was brutally impressive. "Damn" isn't actually what I said when I saw the first numbers, but it's close enough for a family publication. I gotta find something to drop that blown mill into, just so I can really experience 664 lb-ft of torque at 3,200 rpm-as well as the 738 hp up top at 6,300 rpm.

It got me to fantasizing about a "Build Your Own ZR1" project. Who among us can afford six digits for Chevy's new supercharged Corvette supercar? On the other hand, a few of us might be able to cobble one together. A good, used C4 with up-to-snuff suspension, some chassis bracing, and 315-series tires out back could be a good, inexpensive start. Then add an engine like the one we built this month, though maybe a fuel-injected version-we don't want a 6-inch cowl on a slippery Vette. Voil! You have a Corvette with 700-plus horsepower for maybe 15 large. I know it's crazy, but one of the voices in my head keeps talking about it, and I've been listening

In a similar vein, I then made my way to the Silver State Classic Challenge open road race and followed that brute-power dyno session with some more brute power on the open road, running as navigator in the Hotrods to Hell '66 "Chevelle From Hell." You'll be hearing more about this one, but long story short, it is a '66 Chevelle, and it also might as well be a NASCAR underneath. The ride was amazing, as much for the planted, confidence-inspiring feel of the car as for the animal acceleration into mid triple-digit velocities it provided. The voices keep talking about that one, too, as in, "You must make it back to Silver State as often as possible." I've been listening to that voice-it sure seems to make a lot of sense.

Department Of Corrections
In the Nov. '08 story "A Monster Is Born," page 71, the caption showcasing the combustion chamber is incorrectly pictured and is not an AFR cylinder head. To get it right, here's the correct image of the 325 head with the optional CNC chamber upgrade. We should also note that the as-cast 325 head has an 119cc chamber while the upgraded CNC chamber comes in a 121cc configuration, which contributes to added flow and power gains.

No one cares what car you drive, what you wear, or how much jewelry you've got hanging off your wrist. It means nothing if you can't hold your head high proudly. Those things are only surface-deep. They don't define anyone. At times, our society gets brainwashed on unimportant and commercialized items. People are often mesmerized over what everyone else is doing, what they're wearing, and even what they're driving. Instead, they should focus on themselves.

I've never followed the leader per se, and I never conformed to what was "cool," instead doing things for myself and for my friends. My past not only pushes but motivates me. Thankfully, I have grown up with a small group of very close and supportive friends who also strive for the best in themselves. Plus, the guys at QMP Racing have given me more life experience than I could get in 10 years. When you surround yourself with successful people, you are bound to do/be something great. It's almost inevitable. I've got goals, and I've got a plan for the future.

As of now, this month's edit schedule has left me and the CHP team a bit drained. But I'm hungry and I strive for the best in myself and to consistently do better in everything I do. Not many realize it, but most of my scholastic career was wrought with fellow students who would drive home the fact that I would never make anything of myself. I was never into sports, and I could probably count on one hand the number of times I've ever thrown a football. I was the "car guy" who thought about nothing but. Comments were frequent and almost daily. Never did I realize that those seemingly hurtful comments were actually creating and molding a stronger individual. I may not be a rich man, but I can take things like pride and respect for myself to the bank. I make riches through other aspects of life. I get to be part of something that I can be proud of, and that in itself is rewarding. Sometimes, you need to find yourself-step out of the realm of things and get back to zero-start over. Forget everyone else for a change, stay true to yourself and do what makes you happy.
