NAJA's the name, cruisin's the game.

Quite possibly the oldest replica in the Gateway Cobra Club's snakepit, NAJA was christened in November, 2000. The result of 13 months of effort and long evenings in the garage of Keith and Debbie Mueller promptly escalated into a show and go venture. The car was entered into numerous cruises and car shows as well as the 2001 St. Louis SCCA Autocross Series (sponsored by Bradford and Galt).

The 1st Place A Prepared win in the Auto_x was secondary to Keith's getting familiar with the strange handling charactertistics of a hybridization of Carrol Shelby's hot rod AC and Ford's 1989 Mustang LX 5.0 orchestrated through the genius engineers at Factory Five Racing. This car is really a Mk I, but they were not calling them by that moniker back then! The first rendition of NAJA actually had catalytic converters installed!

The Show wins and the Auto-X championship pale in comparison to the personal satisfaction the Mueller's found by taking the car to the Double Venom Spring Fling Cystic Fibrosis Foundation fundraisers I, II, III, and IV in the remarkable town of London, Ohio!!

The last visit there, in 2004, led to the demise of the original drivetrain. In 2005, a DSS Racing Pro Bullet 306, Tremec 3550, and 3.55 gears went in to replace the stock block (5800rpm redline) mangled by a top end featuring Trick Flow heads, 1993 Cobra R induction and EEC-IV, E303 camshaft, roller rockers, and other goodies that could push the rotating assemblies beyond their breaking point! At tear down the original engine had all mains spun/burnt, flywheel radial cracking, same on the pressure plate, harmonic balancer delaminated, and T-5 output shaft bent.

The HiPo goodies transferred well to the new engine, with its stud girdle, windage tray, and Boss 302 style screw in freeze plugs enabling an easy excursion to the 6200 rpm range. Also added were SFI clutch, flywheel, and balancer. Backed by the Tremec 3550, it is much more fun!

But, you know? It would've been nice to see what the new combo could do at the strip. Before the meltdown NAJA turned a best mph of 104+ and an ET of 12.88 at MAR. That was with 2.73 rear ratio and crossing the line in 3rd gear! But, alas, MAR is long gone. About all the Mueller's do with NAJA now is cruise. So, we may never know what it can now do at the drag strip.

But, we do know it gets where it needs to go!
 
Thanks for sharing, GREAT story!

So what was the root cause of the demise of the original block? bottom-end couldn't handle the top-end?
 
Linda & I go way back with NAJA too. We were there to put the newly painted body on while Keith's brother Earl BBQ-ed some fine steaks from his own cattle. Linda got the very first ride with the body "on" but not actually bolted down since Keith was so exited he couldn't wait :D. Sadly, I was also there to assist in pulling the original motor that balmy day and assist with the autopsy. So glad it's all working well these days and look forward to cruising with you some more in the future.
 
Thanks

To my Cobra Brethren.
Honestly, I have not been ignoring you guys. Thought I would wait a few days, as this is a very hectic time of year, before answering any of the questions/comments.

- STL Mark. You are the photographer of the calendar shot. It was taken at the winery on Kerry and Kathy's run Fall 2010.

- TBULL - DSS was easy. A couple of phone calls was all it took to settle on what they could do for me. They sent the well crated assembly to the dock of my employer's factory. I got a "Short" Block assembly CNC level 20 - whatever that means? with some "special" work around the piston skirts, bored .030 over, their pistons, rings, rods, main bearings, stud girdle, windage tray, 7 qt pan, HV pump, cam bearings, and gaskets. 90 day warranty, too. Went together well, and has been very reliable and feels safe to floor any time it is warmed up. It uses 20W-50 oil to help pressure levels. The top end stuff is, relatively speaking, mild. Smooth idle, 18 -22 mpg with 3.55 gears. Mpg was 26 highway with 2.73 gears!

I have "bumped" hard up against the Cobra R rev limiter at least 4 times, with no apparent ill effects. I told DSS I wanted the engine to be supercharger ready, so they set it up for a tad over 9:1 CR and with the E303 cam a Vortech with 6 - 8 lb would be about right - but I just can not bring myself to that place . . .

- MPTech - The stock 180,000+ mile harmonic balancer (redline 5800 rpm) spun the counter weight around on the rubber joint and unbalanced the crankshaft. The crankshaft then gradually "jackhammered" the main bearings into oblivion! It felt like a miss or maybe a dirty injector so I just couldn't stop giving $10 fun runs at DVSF IV!! You wouldn't think 400 rpm could mean that much, but I can tell you these SAE guys know their stuff. Stock bottom end 5800 rpm max. MY top end stuff rev limits at 6200 rpm and can easily go there. Live and Learn. DSS was confident the level 20 Pro Bullet 306 can handle 6700 rpm all day. Life is good.
When it all came out the cracked flywheel, pressure plate and clutch parts, bent output shaft on the T-5 and other things needing attention got their fix as well. NAJA also finally got the long overdue upgrade to aftermarket gauges, with real "night time illumination" - in NAJA blue, of course!

- Tom - excellent memories. The one thing you forgot to mention was it had OPEN headers exhausting under the fenders just ahead of Linda and I. That is the main reason why the run didn't last very long. Whew!

- A Snake - WOW, I am so glad you stepped forward to take the honors of having the oldest replica in the club!:p
 
Hey! Late congrats! I remember the skinning party. :) Took Steve Whitlow for a ride in unpainted LePew and while hitting a curve to the left, Steve's door popped open while he was leaning on it and was nearly close and personal with the quickly moving asphalt below. He was sold then, lol. Awaiting the next sneaky snaky visit from Naja and his handlers. :)
