Re: Black RS/Z & the 1/8 mile... any suggestions?
What gear is in it? M21 trans? Don't need it to fat in the heat. You can pretty much leave the motor alone. The work needing to be done is at the rear of the car on a Z/28.

Re: Black RS/Z & the 1/8 mile... any suggestions?
Car ran a best of 9.16 @ about 74mph, 60 ft. times average about 2.0. The time was terribly disapointing! We need to change a couple things and I think 8.75 is maybe possible.
We had alot of fun and did'nt break anything, so it was all in all a pretty good Thursday night. James has a couple of pictures to post.

Re: Black RS/Z & the 1/8 mile... any suggestions?
It has a M20... the motor is running out of fuel on the top, plus the points are bouncing at 7200...

Re: Black RS/Z & the 1/8 mile... any suggestions?
It may ET better at 6500-6700 rpm's. Are you running at least a 4:56? I am running 72's and 78's in the 780. Mine feels the strongest at about 6700 with a 4:10 rear and an M21. Mine needs at least a 4:56 to feel like anything. Its a dog!!

Re: Black RS/Z & the 1/8 mile... any suggestions?
I like blocking the rear PV on our 780s...it seems a lot more consistent. You sure that thing is running out of fuel?

Re: Black RS/Z & the 1/8 mile... any suggestions?
The plugs are awfully white... Didn't have any larger jets with us last night...
Only have a 4:10... How much worse would 4:56's be driving on the street? 4:88-5:13's would really pick it up. OBTW- 2.00 60 foot times...
