Interesting stuff Gents.

I have gone through a bad spell with the car in the last while.I found that I could stall it out to 4 grand on the street with no wheel spin so I was encouraged by that so I also bought new bigger E/T streets and was anxious to hit the track to see what the new launch RPM would bring for time.

Well I had it stalled at 4 grand on the track and let it rip,BANG.....SHIT. I managed to pull the passenger upper control arm spherical rod-end right out of the arm,bent the shock rod,bent the lower driver control arm mounting bolt and pad,rubbed the wheel-well paint off in a few spots and to add insult to injury the track guys made me travel the rest of the strip which destroyed my new tire.

Now I've lengthened the uppers so they are threaded in by at least 2 inches,no danger of pulling the threads out again,BUT,sooner or later the upper mounts will need to be addressed (looked at after every run!!).Also added a Weiand street tunnel ram which needs fine tuning later on but for now runs good and it pulls hard.Off to the track I go with hopefully NO CARNAGE

Update

The tunnel ram didn't work so great at W.O.T(needs cleaning),so I went back to the Air-Gap intake & 750 Holley,vaccum-secondaries.

Pulled the obscene weights out of the MSD dist & went with the medium weight springs and it gained serious bottom end,the ET street didn't stand a chance,laid some long SSSSS's

Took off the side-pipes and ran 11:90(2,500 elev.) dropped 1/2 second from previous nights ET,Pulled a 1.69 60' AND warped the shit out of the drivers side lower mount,rear-end was visibly out.

My last go around looked like Josh's when I screwed up the upper spherical mounts.now it's the lower(s).

These cars will NOT take any serious grunt with out the rear-end issues addressed ,SO DON'T KID YOUSELF LIKE I DID

Like the gents said"If your afraid of breakin' it ,you shouldn't be racin' it"
