    I was told to post some pictures of the new/old fuel system that we will be installing real soon. As some of you know we run the Hilborn "stack" fuel injection on our car with up to 60% nitro. We have had a lot of fun with the car over the past two years when we could get it out. We have learned a lot from some very big names in drag racing, because we were different we got noticed. What most of them said was if you want to go fast put a Chrysler in it:shock: .
    But if we have to run a Buick at least put a blower on it.
    My wife and I go to as many of the NHRA Heritage races as we can with or without the car. We have been able to get to know many of the people who I feel influenced my desire to go racing.
    Our family does not have the money to race with the "BIG boys" but we do have the friends who know we are here to preserve the Buick in drag racing history.
    The 6-71 supercharger came from our friend Dave in Penn.
    The Hilborn old style 4 port and scoop came from Don at Hilborn along with the fuel pump and fuel accessories, and all the tuning help along the way.
    The new 7" 6-71 intake is being built by Hampton superchargers. Don will be done with the intake in the next few weeks.
    We were able to get a larger Magneto from our friend Wayne in southern NM.
    Tom at Cirillo Mag service is setting it up for our application.
    We are just waiting for the dual drive to run the Fuel pump and Mag out the front of the engine.
    The new short block will be done in the next few weeks. new sponsor.
    With the new Schneider cam and Tom Telsco's rockers along with the low comp 8-1 pistons we can exceed .700+ lift @ the valve. Now to find springs that will work:Dou:
    The last shot was at Speed world drag strip in AZ last year.
    I will post some pictures of the 2 fuel pumps side by side (injected -vs- supercharged) what a difference.
    Any questions just ask.

    Injection is nice but I'd reather be blown

    I like the way your going with this As you know Im going to be building a blown fed one of these days. I talked with Ron over at Isky and we went over what Im going to be doing and he ground me a roller cam to the spec he thinks will work best for my combo. Im still not sure if the cam will work but Im going to give it a try

    Where are you getting your pistons made?

    The Heritage Series is a blast! I helped out on The Dickie's Girl Mustang of Leah Pruett-LeDuc awhile back in Sacramento and Boise. The nostalgia deal is awesome! I'll be helping the Leggitt Team with their new car, it's called Nitro Pirate and uses a Corvette body, they have video on you tube, just search Nitro Pirate.....Fun Stuff!

    Here is the shot of the Fuel pumps.
    We are hoping to be at Speedworld Labor day weekend for the Heritage series.
    Our heads are at the Machine shop getting new valves installed and ground.
    We had sucked in some small rocks most likely at Tucson. The stones got by the intakes but not the exhaust. The supercharger uses a twin screen to keep things out of where they don't belong. I will be making a screen plate for the upright Hilborn after this issue was found.
    5 moderately bent intake valves
    3 bent exhaust valves 2 very bent
    I will update more as soon as I can.

    We will be at SpeedWorld on Friday night but not with the car. The good heads are still at the machine shop. We are playing with some of the angles to help with the load we are putting on the valve train. The car is up and running with a good set of stock heads. The cam was designed for the other heads and just does not sound/feel right:( .
    Saturday we will mock up the engine at Don Hampton's shop to get the correct drive and adjuster assembly for our application.We will also be picking up the new 7" intake:TU: . I will post some new pictures Monday.
    Anyone else going to SpeedWorld this weekend?

    My trailers currently out of the area. I could drive the GS out there, but it's still freakin' hot and I've gotten lazy in my old age :laugh: So we'll be going back out for two races this month on the same weekend. One on the 9/24 Friday night and a Saturday night race the next day, 9/25. Should be cooling off a little by then! Come on "winter" :)

    Here is a quick mock-up of some of our parts at Don Hamptons. We will be back there in the morning to finish fitting all the small parts and measure for a belt. I will try to get some shots up Sunday evening from Don's shop.What a place to hang out:Brow:.
    This shot was taken with my phone so sorry if there is an issue with quality.

    I will post some more shots of the engine next week. Don is going to use reinforced front and rear bearing plates on the supercharger. He wants to go through it for us just to make sure we do not have any problems:TU: .
    Our lower pulley will be mounted to the SFI front damper to be a little easier on the engine. The way it is set up we are able to use the shortest drive possible to keep the belt as close as possible to the block.
    Inside the intake "BOX" is a tunnel ram. Don has ideas and formulas for all applications and he had to use a lot of his ideas on this one:laugh: .
    Due to the percentage of nitro we will be running you need to keep the amount of compressed fuel and air down. That big box would be a bomb if you had a back fire.
    I will be back at his shop next Tuesday to pick everything up.
    If anything else comes up that is post worthy I will let you know.

    Alan I hope it is a good kick in the pants:laugh: .

    Craig I hope to have it all done so I can run at SpeedWorld toward the beginning of next month.
    I am very thankful that even in today's economy companies will still work with you to showcase their products(sponsor):TU: .
    This week I have to add all the new safety equipment to the car.
    We now have to have ( from DJ safety equipment ) 2-10lb fire bottles with 5 nozzles, blower restraint system, engine diaper,and several other small parts.
    Simpson has also been great to work with. We had to move from an SFI-15 one piece fire suit up to an SFI-20 2 piece suit,and different seat belts due to blown nitro rules. I will also have to take my helmet back to Simpson on Tuesday so it can be set up for their Hans device.
    In a week or so we will also have to install a larger fuel tank further forward in the nose. The new fuel system uses 5.75 gallons a minute at 1800 rpm. It should also help to keep the nose down in the beginning.
    Well back to work.

    With the blower do you have to run a full floater rear end?

    Tom as far as I have been told by tech my rear axle assembly ( Ford 9" with Moser and Strange components ) is fine with my application. The car still passes tech for Nostalgia Top Fuel.
    Our axle housing is the Fab 9 Super housing I believe.
    The fuel you use has more to do with SFI spec than what the induction is.
    I will also be making a drive spud for you this weekend if all goes well. Don gave me a nice piece of round stock for them:TU: .
    As for the pistons JE are in the process of making them.

    I was told at the start of this year NHRA changed there rules all blown fuel cars must have full floater rearends. Im not sure how good that info is but it would be a good idea to check it out. The guy that told me runs a blown injected dragster and was thinking about running a light load but did not want to change his rearend

    How much of a load are you planning to run?

    John, make ABSOLUTELY sure you have enough piston dome thickness especially around the valve pocket depressions. We had plenty of V-P clearance but not enough V-P side clearance. Called & asked if we could cut .020"-.030" & told OK. Got to .020" & went through. Not a good thing. Can't weld. Had to have NEW pistons made AGAIN. Wouldn't admit it was their mistake. Said we screwed up, which we DIDN'T!!!!! At .020" thickness, at 14 1/2-1 as soon as, or very shortly thereafter, it would have melted a hole. Then it would have had to be SOMETHING WE DID WRONG!!!!! NOT!!!!!! Use caution!!!!!! Please check to be sure BEFORE you install. Just a word of warning. We were told they would NEVER do something like this one off ever again. Guess there has been some untruth telling here. New pistons sent were thicker in this area. Took off much more than needed as far as side clearance, but didn't add anything to the dome. So now we're closer to 13-1 instead of 14.5-1. How much HP have we given up????
