Sounds like that's the answer, sort the launching issue & enjoy mid/high 11's (or as Ken said, maybe the tall first IS the launch issue ) Then a solid cam + better first gear if you need more. Have you weighed the car? Just curious, turning 115 is pretty impressive with "just" a magnum cam, torker & a port match + 4.30's Edited by jpnjim - Dec/17/2014 at 8:51pm |

Havent weighed the car but its all steel with a gutted interior. to answer before I run it on race gas. Not to get off topic how do all you 4 speed guys reccoment I launch the car? I have a Ram powergrip clutch right now and drag radials I am not going replace until they are used up. Shifting under power hasnt been a problem. Give some insight onstarting line technique.

Clamped rear spring halfes yet?
What kind of traction baron aid do you have. What tires, air pressure adjusted on each run? Limiter on left front suspensition Strip the tire and video it, make sure tire is not moving on rim. Rims screws? |

Do you vary your rpm at launch. What rpm does it like
Are you speed shifting? Video that pass, let's see it so some of us drivers can check it |

Each car is different. You will need to raise of course or lower those starting line rpm to find what that car likes on that day at that track in that weather with that time. Fine line between bog stumbles and go and wheel spin. U as the driver has to find it. My suggestion, screw trying to make a full pass. Work on starting line and short time techniques, till you get them down right. Then move to the next half of the track. Shift with no clutch, at speed and with accelerator shoved through the firewall. Lol If up where in houston, I'm free and would show you some thing. |

figured I'd post this here http://schneidercams.com/292-02Famcsolid.aspx if you like the Comp 290b cam, but the .570 lift is too much, Schneider makes a cam with almost exactly the same specs, but with just .544" lift. I never used a Schneider Cam, so I can't speak to their quality, I just thought it was interesting they have their own version of the 290b, using the 106 degree lobe centerline, but with less lift. |

I run the same cam (Comp 292) in a 343 with an airgap and have run 11.8 @ 115mph with 1.69 60'.
I was running std rear suspension in a Javelin, 3500 converter, so leaving a little on the table. As others have said get the 60' down and that should get you close to your goal. I am interested in the opinions your getting for cam recommendations because i am also looking at changing out my cam for a larger solid and moving to a torker intake to pick up a few tenths. |

A lot of great advise out there! I would find out what heads you have and work on a cam that will fit the flow of your cylinder heads. All the power comes from a well balanced combo of intake,head and cam. I like eddy heads out of the box. I use Engle solid K-7 cam and Indy Intake. Holy crap what a difference it made!!!!! I get 11.40 times and 117.00 mph. This car weighs 3167. not bad for a street driven car on 93 octane pumped gas.

to everyone posting ETs, what rear gears & transmissions? It's tough to match some of those numbers with a 2.23 first 4spd, but its still a good reference. To the last post, I'm surprised to hear of an Indy intake working so well in that combo, did you match the Edelbrocks to it? |
