  1. Very impressive! Do you have any Sponsors?

     

    No sponsors....just the potential contingency payback from an eliminator win or runner-up. I work in the performance aftermarket business and that helps to save significantly on parts.

  2. You are flying, congrats! Do you know Vern B.? He runs a 1973 351C. Chuck

     

    I met Mr. Buchanan at the US Nationals a few years ago...I was spectating. He gets a lot from his '73 combination...very fast in his class.

  3. Great effort on your part. Thanks for sharing with us. Are you crossing at about 6950 RPM? Keep us posted. Chuck

     

    Closer to 7200 Chuck.

    I guess I didn't allow enough for convertor slip. Thanks for joining the site.

     

    I actually hooked up 5 years ago..... just been hiding.

  4. Are the NHRA and IHRA rules pretty similar?

     

    Very impressive ET for your car, by the way! How much does it weigh?

     

    Some subtle differences between the two - Indexes are 3 tenths quicker in the NHRA. 12.00 vs 11.70 in E/SA. IHRA allows one battery in the trunk; NHRA wants one of equal size/weight left up front. NHRA will not allow aluminum diff carriers unless OE for the car. You can use a 10.5 wide slick in the IHRA. Nine is the max in NHRA; 30" dial for both.....I think that's most of them.

     

    The minimum weight for my combo in "E" is 3420lb including the driver.

  5. A good friend of mine used to race his 70 Mach-1 M code car in AHRA stock class g/o. At one time he held the world record for that model of car with an ET of 12.30 (as I recall).

     

    ...anyway, the stock class had some interesting allowances for the engine...seems they allowed for different cam timing events but required the lift to remain stock.

     

    What mods to the engine does the NHRA allow for your class?

     

    Without going into a great deal of detail, the rules tie your hands in a couple of key areas; air flow and rotating weight(no power adders of course). Lots of changes in recent years - any valve job is acceptable, roller rockers are OK now and you can bore to +.080". The IHRA makes their rule book available to anyone online in digital format.

  6. That is pretty hot car for sure. Can you share what is in the car to get it to this point and stay in stock rules? Looks like it lifts very even how did you stiffen the chassis?

    When I get my 72 Q code automatic back together would like to do some light strip runs nothing like yours just for fun. I was also interested in front and rear shock combo you use? Do you have a video of a run you can link?

     

    Sorry David, no video - we'll capture some this year.

     

    The shocks are Calvert 90/10 with fixed valving in the front and Strange double(compression & rebound) adjustable in the rear. We use Calvert traction bars with Flex-Form composite mono leaf springs along with stock type front suspension that features upgrades from Open Tracker and Global West. Frame connectors keep things rigid.

     

    The engine is a '72 351C HO rated by the NHRA at 325hp. It actually produces closer to 500. The rules allow the use of a Ford aluminum dual plane intake along with a 780 Holley vac secondary cab. The trans is a C4 with a Dynamic converter that stalls at approx. 5400 rpm. Rear end is currently stuffed with 5.14 gears spinning 9 x 30 radial slicks.

  7. Making some progress towards my goal of running at least a second quicker than the NHRA E/SA index of 11.70 sec in the 1/4 mile. As of last September, the best run has been 11.055 at 118 mph. A few more upgrades in 2017 will get the car into the 10's at over 120.

  8. This information may not be relevant to the purpose of the topic, but it is an indication of how much weight may be removed without radical body panel or glass modifications.

     

    My '71 "H" code Mach 1 is a legal NHRA Stock Eliminator race car that weighs 3,000 lbs. before adding ballast and driver weight to reach the necessary scale weight for my class. We are allowed to remove components such as o.e.m wiring, wipers, heater, back seat and original fuel tank. It has Wilwood disc brakes up front/stock drums rear. The stock leafs have been substituted with one piece composite style springs. A roll bar and frame connectors were added to the chassis for strength and safety. The standard interior retains original seats and dash - no console. For classification purposes we call it a '72 with 351CJ horsepower rating of 266. Probably some excess weight left, but for now, we're done!

  9. 1421357208_St.Thomas2013.jpg.d31a70de44813afc84fb3cc59984b997.jpgIMG_20130805_163517.thumb.jpg.11b8b5ae5d7922224e48f43ccf33c888.jpgIt's been 2 years since my original post on this thread. Countless hours of garage time and a great deal more learning than racing! Time for an update.

     

    The plan from the beginning was to concentrate on the platform rather than becoming obsessed with chasing elapsed time results with the initial engine combination. We knew that the chassis would deliver continually improving numbers if it had the right pieces from the beginning. With a sound foundation, the addition of more power could be predicted to get the program where we needed to be.

     

    After a couple of testing days and some frustration with timing a locked-out advance distributor, the car was posting some acceptable results. Circumstances would prevent us from making any meaningful 1/4 mile runs this year; the posted results are from 1/8th mile competition.

     

    Our development engine was an NHRA Stock combination based on the 1972 351C CJ with a factory rating of 266hp that is refactored to 328hp for class designation purposes. At 3400lb. we ran a best of 7.49 @ 90.18 MPH. Next season, the package will be a '72 HO based piece which is 275hp factored to 325. The car will be in the same weight to horsepower class, but most would consider the solid lifter HO to be a superior option. It is favoured by most, if not all of the active Cleveland-based Stockers.

  10. I love drag racing and especially love to see Fords do well. I ran Stock Eliminator back in 73 and 74. Let us know if you are coming to the US Nationals in Indy over Labor day. I usually try to attend that.

     

    The program won't be up to US Nationals standard for a year or two. I will try to post a schedule of events that we plan to attend next season. Indy is on the "bucket list".


    Welcome from No. Illinois. What are you running for times?

    Jim

     

     

    Nothing to report as yet....in the hands of its previous owner, with a Jerico trans, the car ran in the low to mid 11's. We're anticipating similar performance to start with. Looking for the high 10 sec zone eventually.



    Welcome from West Michigan.

     

    Have you had it out yet. I crew on a 72 e/s Mustang running the "R" code combination. We race division 3 events around the midwest.

     

    Maybe I'll see you at the track.

     

    No runs on the car Jeff. We'll be out next year and should get to Martin or Stanton...also sent you a PM.

     

  11. Very cool, welcome to the forum. Did you build it yourself? Got pics?

     

    Not many pictures to share until it's done. I will post a few. We've updated a car that was active in the Southeast for many years until 2007. Lots of current technology applied, especially in the suspension, wiring, brake and fuel systems. Props to the folks at Moneymaker Racing, LaPorte IN for their assistance with parts sourcing and expert installation of suspension and brakes.


    Welcome from North Carolina. Look forward to seeing the trophy pictures!

     

    Thanks!! I'll remember to smile if I get the opportunity.

  12. I'm looking forward to sharing some of my drag racing experiences with the members. My '71 Mach 1 will be found at tracks in Northeast and Northcentral Canada and the US, competing in NHRA & IHRA Stock Eliminator. We'll classify it as a '72 to use the lower compression Cleveland combinations.

     

    Drop by and say hi!!
