drove to the track, great. Car felt good, then this be? http://www.youtube.com/watch?v=p93jNXMKFWA&feature=youtu.

Seems to pull hard until 5800-6k then breaks up. Fuel pressure is fine, plugs look good, it just starts dropping cylinders. Take a look alisten. Swapped the Orange box out, did a little better but still started farting at the top end. everything is new excep the coil (blaster II 15 years old) any ideas? All in all we had fun, Chris (440pursuit) ran his new Demon back-2-back-2-back 11.05's. Drove home all good..

I had a similar problem and it turned out to be a faulty connector on the coil.

sounds like fuel starvation to me. Nothing in first gear then all through the second half of the track. What kind of fuel pump?

Chris it's a holley blue pump, ran it last year no issues, holds 6.25lbs (ca adjust for more) all the way down the track. Air was real good today...

I'd try another pump. I run 2 blue pumps for good measure. Should be running 7-8 pounds pressure.

Please tell me you have a steel billet brum in your 727. Does not look like you are letting the car move far enough forward after you are cleaning out the motor. Ask Chip what can happen by doing that.

have you checked that your carb opens all the way?

if the carb opens fully,(check by having someone flooring the loudpedal with engine turned of and look down into the carb to make sure,or put your hand on the throttlearm on the carb while someone holds the pedal down to make sure you get an actual fully open carb) otherways check for electrical faults or valvesprings.

carbs are the same as last year, evrything is except I put in a new steering column.
Did the same thing I always do in the box, burn out, roll forward clean the plugs back in 1 and move into the beams.
I'll try bumping the pressure to 7. Had it this way last year w/ no issues, wonder if the 14mph head wind had anything to do w/ it...

change the fuel pump! Then put a good ignition in it.

I have an MSD new in the box on the shelf. It will be going in soon...and I'll bump the pressure up... Just wondering why it didn't do this last year. Mayeb I'll get the Holley Black. Thanks..

Probably from sitting around all winter. Sometimes they just go. Does Chris have a pump you can try?

I'm sure he does, thing is we had a mild winter, probably drove it twice a month or more... It does sound louder, if that's possible. Would the pressure still be decent if the pump was going bad? It held a steady 6-6.25 all the way down track

Man your are asking for trouble.. staging like that.. you need to put that car in 1st gear and let it move forward a least 2-3 foot.. Not sure why you rev it up like that/clean it out ? is something wrong with it ? Not a good thing to do..you have some bad habits there..we have a ford guy that does that..we all pick on him and laugh at him. if you have to do it there is something wrong with the car..trust me it don't sound cool..

vern it roll at least 5-10' after clearing. They don't give us much room that's for sure. Usually I just take it up to about 3k hold or a second and move forward...seemd like it wanted to stall so I gunned it more than usual.
Still have the factory amp gauge hooked up, looks good.

Sounds like good advice.

1. Check all connectors and voltages.

2. Like Duane Says- Your'e blowing the candles out" with the Creamsicle box. Get the MSD on with legit voltage.

3. Fuel pressure weak now, too. I have a pump, but Crank yours up and watch gauge thru run. You need 8-10psi.

4. We'll check the adjustment on the carbs. I'll give you the Dominator and and Weiand mini tunnel. You'll really need to get gas there, then!

5. Raise antenna's on Gazoo's Helmet!
