Classic over carburetion problem?

Hi everybody:

Now that I have over 300 miles on this 340 I'm getting to feel that there might be a problem like I thought. I got my friend to drive it also and he thinks the same thing. It should go WAY better than it does especially in the burn out awards. It hardly breaks the wheels lose :(


1970 340
Ground and drilled rods
Speed pro forged pistons
ported 2.02 J heads
Comp Cam 488/491
750 Holley vacuum secondaries
Edelbrock Airgap intake
Doug’s Ceramic Headers
Super 44 Flow Masters
Exhaust 2 1/2"
727 with 2200 –2400 converter
8 3/4 Dif with 3.55 Eaton trutrac
HP haven't a clue


Maybe too much cam and carb...

Throw in a set of Rhoades lifters and tune it in right...

Here's Eddie's 340 Dart with a milder cam, LD340 intake, and Holley 600 vacuum secondary carb, Doug's headers, 8 3/4 with 3.55's.... idling from 800 and stomping the gas it will break the tires loose....
