Hi

I just baught myself a 750cfm Double Pumper Holley HP Street carburetor for my stock 383ci 68 Charger. I also got a Wieand Action Plus Dual plane intake manifold. Replaced the old coil with a Pro comp coil (40-50 000 volt) and NGK IRIDIUM spark plugs to replace the crappy Champions.

This car now hits 80mph in 2nd gear. I couldnt believe it can go that hard with a stock 383. Still running the rubbish original headers. WHen i stick 3" collectors on with new exhausts... Wonder how good it will go then.

You also can not beat a DP carby. Totaly responsive, does what you want it to, power is there instantaneously and its more economical than a Vacuum secondary (if you control your foot to drive off primaries only/all the time)

Dont even know why they make VS carbies.

Curious;  what gears (ratio) do you have in the rearend?

[G-man]

Dont know. When I replace my clutch with a heavy duty clutch (Next week) should be able to tell you the Ratio.

I believe its more than 3.23.

Might be either the 3.91 or the 3.53 (or whichever the one is inbetween)

Vacuum secondary or mechanical? I took my Carter off and put on a 780 duel feed, but it was vac secondaries uh huh.

And school bus gas don't go well into 12.5:1 squeeze, and you can't light up for at least 3 days cause school bus gas tastes bad yup.

80 in second? Sounds like a 3.23 in back! Or 3.08...

   Two words come to mind when I hear 80mph in 2nd.  REV LIMITER.    If you got one great. If not, get one.     Do you have an electric choke?   I can't wait til I get my new carb but I guess I'll have to.  Any pics. ?

The 750 cfm HP street Holley has NO choke (mechanical secondaries - Double pumper)

No choke is awesome also.

Revs... Might off been 7000 I know it was screaming its head off and I dont have a RPM gauge...

Will get pics off all the new goodies on the car... give me a bit of time.

Hmmmm.....you think @ 7000rpm with a "stock" 383 eh? The valves will float way before then...
And if you don't know why they make VS carbs?? Really???

RPM gauge???

You talk funny.....

Good luck with the DP on your stock engine........they are a good carb.
