Danny: Could you e-mail me at jkaekel@laneautomotive.com. I've got a couple of questions for you. Thank you.

Jim, Please take this the right way. If your questions are about Craigs Cutlass and not about women or fishing, I'm going to have to ask you to contact Craig direct. He's spent a fortune on an intense 3 years of r&d and it just wouldn't be ethical for me to discuss his car without his knowledge. I'm sure you will understand my position.--------Danny

Danny I hope to get a chance to meet you. I have owned the Tanker in the past and currently own the 455 Black K/SA with the title still in your name LOL

anyhow hope to run into you at the races this year. Later Daran

Dan Lattimore · 12-09-2010, 08:50 PM

Daran, You better go put that title in your name or I'm going to file for a lost title and you will meet me sooner than you think. Hey just teasin, If that were the case Kenny Shawver could come over anytime and take back my 71 stocker. :-) -----Danny

back to my original posted question. in my old AHRA stock class car ['56 Chevy Nomad] i have a 9" ford which was legal under the then AHRA rules. i have about $1500 dollars in that unit. now in order to run under the new NHRA stock class i would have to run a 12 Bolt, as there is nothing else worth consideration. it is very possible to run a 265 with a stock 12 bolt housing with welded tubes [no need for a fabed up unit] and then lots of $$$$$ to duplicate exactly what i have now. and again the 9" looks just like a '56 drop out, whereas a 12 bolt looks nothing like the original. NHRA is so picky about a piston # and then lets a racer place something completely different for a rear axle. i don't get it. and i am ticked.
suppose for a minute, since the AMC subject has been brought up, that racer A spent big bucks to put a dana 60 in his AMC and then NHRA said only AMC rears would be legal. now you have to duplicate another rear to get exactly where you just were. and have a rear with almost no resale value [being car specific].
it is entirely possible to make a '56 car axle housing into a race unit. 30 spline MoPar side gears in the posi and big ford bearing ends with big race axles and some type adaption for brakes and several mods to the case. [i still have my Jere Stahl 5.57 with all that done]. in the end i would still have a smaller dia. ring gear, and lots of $$$$. what's the purpose
now let me get on my soap box [wasn't i just there?]
the '57-64 Olds/Pont. rear was just BIG, not strong. in a popular hot rodding survey, in a list of the top 10 rears, usable for drag racing, that rear came in 7th.
the 9" fords uses about 4 more horsepower than a 12 bolt. using conventional gear lube. maybe when looking for that last hundredth, that might make a difference. however you can loose more than than by not having the lube up to operating temp.

all in all, if NHRA says rears axle updates in mfgr' only, then so be it. maybe some guys will build new '56 chevy stockers and not have to worry about my problem. i do not have to run under their rules. that is my choice. in the end i wonder who really looses. NHRA has crapped on door slammers for way to long and are now crying for help with car entry. maybe they will change with enough protest. i will start monday.

i do appreciate all the input.

I would like to add to this thread an experience I had. I am building a 60 Corvette and was looking to go (Stock) racing. When it came to the rear, I wanted to use a 12 bolt for different reasons. Everyone (friends, racers, NHRA tech personel) said, no problem go ahead an use it. Everyone except Wesley Roberson NHRA Div 4 tech. The rule book said the replacement rear must be the same "type" from the same corporate family. The word "type" meant spicer (rear loading) or 3rd member (front loading). So you could not use a 12 bolt in the 53-62 Corvette (Wesley). After doing some investigation of my own, I found many violations to the rule book on rears. Including a few direct violations setting on world records, and not just Chevys. I gave no information on the cars and/or names. I did go a few rounds with Mr Bruce Bachelder at NHRA. In the end the 2010 rule book was ammended and the word "type" is no longer there. Now it's just a rear from the same family. So you guys with the 55's can go ahead with the 12 bolt "and be legal" now. After all that mess, could'nt get a 9 inch tire on the Corvette anyway.....so I went to a 10.5 and had to move it to S/S....there were several other issues on the car that made it more favorable to go S/S.
