Yenko Deuce Timeslip - Page 5

Geoff, sorry to come down so hard. It is just that we have been through this a lot of times. People have come on here in the past and have said that our times of 13's and 14's suck for muscle cars but what they don't understand is that those times are a lot harder than then they seem to acquire with a muscle car in stock config. Again, I am sorry.

Marlin, I finally found the timeslips. I attached the one from JJ's run. 2.305 60' and a 13.878 over all run. By the way my car had a 3.73 rear ratio. I changes out the 4.56's that were in my car shortly after I bought it from Neal. My exhaust was bigger than stock I think. Marlin would know that. He knew more about my car when I had it than I did, but still couldn't beat me!

By the way, Neals son told me that they did a best of a 13.3 in my car.

Daaaaaamn...... a 2.305?

Geez, so much for the bigger gear theory too. Pete told me years ago that the best combo is with the 4.10 gear, not the 4.56. Thanks for the slip, I'll have to compare it to my best one and see where the difference is - probably every measurement point

No problem Frank, just trying to get some info on these cars. I do know how hard a high 13 low 14 pass is, especially in " stock " trim. My 84 Mustang which I bought new runs high 13's with few bolt on upgrade. Stock block,cam ,heads etc. is rated at only 175hp. I have run a 1.8 60 footwith this car with 373 gears. DRag radials. Unfortunetly the car runs out of hp on the top end but the first 3 gears are a blast . It took a LOT of time to figure out how to run this good. On the flip side my L78 went 12's without too much effort,but there was a learning curve there as well. A deuce that runs high 13's on polyglas tires is very impressive and must have quite the top end charge...

I'm looking for that top end charge! I'm usually looking at Frankies 1/4 panel instead

Keep trying Marlin !!!!

Guaranteed, anyone going to race at a strip will come home humbled and humiliated. Not as easy as it looks, especially on street tires with a 4 speed. It's happened to every racer that I know.

Hmmmm..... I compared JJ's run to my best run, and the differences are consistent throughout the run.

-------Marlin------JJ----Diff

60'----2.237----2.305----<.07>
330'---6.109----6.079-----.03
1/8----9.262----9.102-----.16
1000'-11.967---11.692-----.27
1/4---14.252---13.878-----.37
MPH---98.690--103.040-----4.35

Factoring out my 60' advantage, it's a tenth at each measuring point

Sounds like the consistent advantage of 2.5" mandrel bent pipes supports the consistent advantage proven between the slips!

ummmm...and the little thing called RPM's...Marlin why dont you build another motor and shelf your numbers piece and run it like you stole it...

Nah, I'd rather find another deuce without it's original drivetrain, and restore it just for pure stock racing

The deuce with headers and slicks would be well into the twelves as well, pretty stout for a 350 car

The SuperCar moniker is more about ordering hi-perf combinations via the COPO, and dealer installed stuff as opposed to 1/4 mile stats - keep in mind that Yenko Stingers are considered SuperCars, and they would probably wouldn't impress anyone with their 1/4 mile et's

Hmmmmm............Which "Stingers" were you referring to???
