    Do I need a new MAF and injectors?

    Why not take it to a Dyno facility where they can look at Injector duty cycle's and MAF voltages. Only way to know for sure if you need to invest in new parts. RF

    Blew up motor in 99 this week!

    Just to clarify (for the record)...that motor was assembled by Archie Somers of Somers Machine. The crank was "magged" prior to install, but showed no signs of any problem. It was an unfortunate, unforseen and costly break, but that's racing. Sometimes we have a bad season, but hopefully this...

    New engine will not idle - HELP?!?

    Make sure to also use gasket cinch. I have seen 2 cases of the gaskets creeping in the last 3 months. They were torn at the bolt location and seperated on the bottom side, so you could not see the cracks. They block the runners and performance is affected. Also re-torque the intake bolts after...

    New engine will not idle - HELP?!?

    If the plug gap chance improved the situation, go down a bit more to .035. You might be on the right track, at least it appears that way. On the 4 corner idle mixture screws...run them in until you hear a change in idle...idle should come up bit, and then back off an 1/4 turn. Do that on each...

    Camshaft selection...lets get your thoughts.

    You might go on line, go to www.compcams.com Fill out the cam questionaire and see what the experts recommend for your combo. Might as well get the ideal cam. After all they only spent 6 billion dollars on research. Food for thought, Ron

    Camshaft selection...lets get your thoughts.

    The lifters are ticking? Or the rockers are ticking? Things out of adjustment? Oil getting up top OK? Ron

    They are bolts. Not studs. And get the 5/16 inch design. Because the tubes are so close to the holes, you will save yourself a lot of knucle busting, by using the smaller head. Ron

    Adjusting Speed Demon

    14 to 1 is just a bit to scarry for me. Take a look at what Dynojet recommends. Qoute: What A/F ratio should I be looking for when I'm tuning? On a naturally aspirated engine, you'll make best / safe power between 12.8-13.2. Vehicles running "power adders" will need to run a little...

    Adjusting Speed Demon

    I would drop 2 jet sizes in both front and rear and run the car. See how it performs. Ron

    Sound like a bad needle and seat on my demon?

    Is the fuel pressure measurement you are reading flowing or "deadheading"? Also are you running any type of bypass and what is the pressure at the pump? Where is the regulator located in the system? and have you done a flow test? For some reason your floats are getting pushed up, but if they are...

    Jetting my carb??

    Make the investment. Not very expensive. www.summitracing.com has the jet packs for $39.95. I checked ebay and found one that has a bid of $9.99. Here is link: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7910380702&category=33551&sspagename=WDVW Ron

    Header Installation

    I like to start with the 2 end bolts since they are also the gasket locators. Insert the end bolts (loosely), then drop the notched gasket in place. ron

    Jetting my carb??

    I would take a vacuum reading as the next step, and make sure that you have the right power valve, based on the vacuum. There may be a delay in opening the valve causing a "bog", or it could be dumping too much fuel. I looked at what BG ships their 650 CFM with as far as jetting, and they...

    Jetting my carb??

    I would first look at the pump operating lever clearance. There should be "zero" clearance between it and the over ride spring. Ron

    Header Installation

    All you need to do to "tilt" the motor a bit and get the headers in is get the car up on jackstands, then loosen the two bolts that hold the engine mounts. Get a short lenght of 2 x 6 and find a suitable location to raise a engine a bit. Do one side and then the other. I would also suggest...

    Jetting my carb??

    Leave the jetting where it is and drive the car. A header change should not affect jetting. Increased airlow into the motor will. As an example I recently installed an carb tray to increase flow into my set up. The AFR changed from 12.8/13.0 to 13.7/13.9 to 1. That required an increase in jet...
