Stan, What did it run?
Quote:
If all that is correct, I don't think I can run a quarter with the tires and gear in the Colt.

What is the shift light set at?
It only sounds like it is turning about 5000 when your shifting. Maybe?

I would give it a longer burn out and launch at a higher RPM and then hold on! :D :D

Congrats! Good to see it running!

Rick
I just looked at the slips.
It ran a 9.75 @ 75.81
That is 4215 RPM in high gear.
So I guess I need to really check the shift light indicator.
On my first run it picked the tires around six inches, carried them about 3 feet out and then came down.
That run was similar to the second run ET wise and MPH.
I did cut one good light and it's consistent (ly slow).

Not sure how much higher I want to bring it out, that first launch snapped my head back.
I really need to decide what RPM to launch at.

That hard hit now will not feel as hard later! :D At 4200 you are just starting to pull. :D You will sneak up on it little by little.

When I let my friedn's daughter drive my car I lowered the shift light from 6300 to 4900 for her. It slowed the car down a lot.

As Rick said, more seat time will help immensely. :mrgreen:

Denis, I need to make sure it's correct, might raise the rev limiter a couple hundred also.

Very exciting! Seems you should run in the 8s at least with that MPH. For sure you will pick up quite a bit when you rev it higher. My experience is that Slants don't pick up a ton of time with tall (high numerical) axle gears. Maybe switch to a lower gear so you're not shifting so frequently?

How heavy is the flywheel?

Bright side is you learned some things, had fun, and loaded up a running race car. Successful day indeed! :mrgreen:

Thanks Lou, 4.88 in the Dana.
Maybe change tires.

Dennis, it's 35 lbs. plus disk and pressure plate.
Has to be over 40 lbs.
I guess I do need to keep that weight spinning.

I left @ 5200 with the '69 Dart - ~3400# with a 4.10 Gear. Stockish Street slicks etc.

I am pretty sure Team Grean Left at a Higher RPM as well.

Glad you are getting it out there and having fun!


Greg

Working on my Webers. I got my jet set and have them all together.
Next working on the linkage and fuel line.

Looking good Stan!

PS. I accidentally ordered a shim set for a Dana 60 ring & pinion. Not worth sending back. Send me your address again and I will mail them to you.

Rick

Thanks Rick, that is a very nice gesture.
This linkage is a mess!
Going to spend a little time getting it all sorted.
And fuel lines too.
Do you find you have to remove the tops often?
I am thinking about three separate lines if I do take them off.
Float level and anything else I might need to tweek.

No, I set the float levels when I installed them and never touched them until I removed them and changed the venturi to 40mm.

The Red line linkages are a bit nicer with 3 mounting posts.

Ryan is running the Clifford on his. Pretty sure he is running 3 separate carb linkages

Got my linkage almost done.
I need some 10-32 left handed jam nuts. And the right ones also.
Forgot to order them from McMaster Carr.
Here is what I have now.

Rick, I got those shims, thank you.
