Extra hp out of my 340.

I don’t think fuel line size is an issue here. Just the possible state of tune between the two carbs and the noticeable difference in performance esteem the Avenger and a DP.

The Avenger carbs are known to have an issue with there secondary opening bogs.

For myself, I would use the 750 dp with a small block 4spd performance car. Tune the smack out of it!

Also now that we know wha cam is in there, even though I wasn’t initially to keen on a 3.23 - 3.55 gear change, I will now fillip and say that would be an excellent choice and not a 3.7- gear.
