Need Some Help PLEASE!!!!

[Racer747]

I have a 02 black front rocket. The car doesnt seem to be getting up on its bars the back left tire doesnt seem to be moving forward and I can't seem to get my speed over 74 mph. I have changed gears from632 to 648 to 657 and all it seems to have done is change RPM not speed. I am running a 358 but it runs on menthnol. I have scaled the car to the rocket book. The 4-Links are LT-- middle hole LB--middle hole RT---middle hole RB--- middle hole the scale numbers are Left--54.65 Rear---55.25 RF--LR---- 50.3% Right---45.4% LF---633 LR--774 RF---522 RR---648. The lift bar is on the second to last hole measures 36in the track is 1/3 mile little banking stop and go track the spring setup is LR---200 RR--250 LF---500 RF--400 Lift bar spring is a 375. Looking to get some help on what i can do to get more speed and try to figure out why its not getting on its bars and why the tire doesnt seem to be moving

Length on left upper bar? Might need to shorten it with bracket

[Racer747]

The left top bar is measured at 18 1/4 what the rocket book calls for

175 on the lr spring that will help, and your to stiff on the right front spring.

Check transmission for binding

Not a rocket guy but isn't a 375@36" a tad stiff on the lift bar for a 358?

They usually suggest you start with a 300.

That's a long upper, 16 3/4 -17 is a short, but you need a bracket to bolt on. It will help get up on the bars and works well on short tracks(big ones too, but mostly for short ones). With an 02 you might also need to shorten the LLB also. The other suggestions are good also, but getting up on the LR with the long bar is slower and doesn't happen as easy.

What are you running for shock or shocks on the LR?
