does it matter which carbs are being used?



works with both carter and edelbrocks, i just switched out a set of 750 carters to edelbrock 800's leaned them out a tad and went with a little richer metering rod for this weekend.
i feel it was too rich at launch only getting a 1.41 60 foot. and it slowed down 3 mph and .1 with 3 jet sizes richer.
i definitely thought the .116 jets would have woken the car up but no, even with half way decent air, it slowed down so ill be at .113 square for this weekend.



Ok now I'm confused you start this post letting us know that you have the secret to tune these carbs for a .15 better et and then you say you adjusted "yours" and you lose et so is this a trick post



Russ, no this is not a trick post, i already found the .15 increase, i was just looking to see if i could squeeze another .0500 out of the combo, i jetted it up some more figuring the air was a little better but it didnt work, so im going to try a jet configuration.
im looking for some more jet combos from a few more 440-25 members then ill all let you in on the easiest cheapest way to pick up .15
