Weather beaten '68 Charger 4-speed Hurst

don't worry
it always is. you can feel when the rate of acceleration decreases you need to change before then. after a few goes just count
123 change 123456 change 12345678 finished thats about right for a 17 second 1/4 with 2.92:1 rear...i have learned to be consistently slow
you can't keep an eye on the track the bloke next to you and the tach at the same time
and you can't hear anything if hes got open headers.
avoid the burnout box with street tyres they just get wet
don't bother burning out with street tyres. 1) the compound doesn't like heat and 2) you need your clutch cool ish
and i have found the lurching back and forth and thumping the wheel doesn't make you go any faster.

And don't forget to adjust your tyre pressures.I'd start with about 9 or 10psi in the rear droping a a bit each pass untill you feel you have reached it's optimum presure: ie the csr feels safe and you feel safe.Fronts want about 38-40psi.Good luck.I'll see if I can get down but HinD might have other plans for me.
9 or 10 psi might be a bit low if he's on ordinary street radials,might be better not lowering them at all...cant say I've ever had much success running street tyres at low pressures...maybe start at road pressures and work down
9 or 10 would be ok for drag tyres or slicks
not that I know what i'm talking about

I did the ol' scientific study on my oil level using a new chinese made dipstick, the kitchen tap and the wife's measuring jug...
When the engine was apart I found out how much 5 ltrs of fluid filled the pan. 5 ltrs was good as it was still well below the windage tray by a nice amount (plus taking into account oil flowing round the engine).
Marked the pan off both sides, placed it on the engine (upside down on an engine stand) and slid it along until it was as close to the protruding dipstick as possible and marked that off to the same level (using two used gaskets and the windage tray to simulate install).
That became the 'full' or 'max' mark, which I notched with a junior hacksaw.
I ground off the factory marks (way low - which would have given 3.5 ltrs max!!!) and notched in a min mark - typically about 1 - 1.5 ltrs difference and a space of about 3/4 of an inch.
Hey presto! an accurate dipstick!
I know you're not going to go to this extreme Jonny but my point is 4.5 - 5 ltrs is enough.
Of course the size and shape of the pan itself will have an influence...
As for the 4 speed shifting, you'll get the feel for it

Stick 4 litres in there & run it down the 1/4 , if oil pressure drops to zero then stick another litre in there.
Stock pan & oil pump then 4 litres should get the job done , high volume oil pump then add another litre.
You're engine is freshly built so 4 litres will be plenty , a tired engine with crud up on the heads will require more oil due to drain back issues (assuming bearings are in tolerence)
Good luck with the racing , are we betting what times you gonna run? , i reckon 15.9 sec @ 88 mph , tyre pressure around 22 psi.

Had a fun day at the strip. I'd love to say it ran 15s......or 16s.......but sadly my best was a miserable 17.2. Felt quick but the starts kept bogging down. i think I might have to re-adjust the carb too. Let the tyres down from 28psi to 22 and the car got slower
Hey ho, didn't wanna break it and came away happy. Have scrubbed a new 'maximum' dipstick level with 5-litres in the sump. Oil pressure still faultless.
Watched the Surrey Muscle General Lee do consistant (damn impressive) 9s.

At least the only way is up! Every mod you do now should bag new PB's!Patina Charger wrote:Had a fun day at the strip.
