The easy way for you to know if your carb is not tuned to your set up is try one that works good on a motor close to yours.The main jets might be close but the fuel curve could still be rich or lean at the low end of your on track rpm.This can be tuned with the high air bleeds and the emulsion bleeds.

With more digging I came up with the flow numebers from Ron's on my -10's ([email protected] and [email protected]). That puts the peek power at about 7400 way above where I want it.
I picked up a set of brodix rr200(cheep). they should work better in my rpm range. I will see what it runs soon and post the times before I make any other changes. Thanks agin for all the help.

I took it to the track yesterday (7-30-10) with the brodix 200rr's and it ran 10.93@at 122. we got rained out so I could not tune it much. The exhaust temps were showing lean(jests or running out of fuel). It now pulls the front wheels and carries them out but the chassie unloads after. I now see mid 10's with no problem. Thanks agian for all the input.

I have built this car very close to a buddys car every thing the same but he has a set of sportsman heads same cam same motor. he has a 4.00 gear and a 28" tire. he runs consistent low 10's. I still think it should run in the 10's with this combo. Maybe I am just spoiled with BBC'S . I had a 427 with old out of the box dart heads that ran 8.06@170 in my #2000 altered with 4.10 gears and a 33"tire. Thanks agin for all the ideas. Keep them coming. thanks bill c
Now...Had an old set of -8 that had lots of work done to them over the years.Supposedly flowed 301@ 700 on the intake...But the camaro was a pig. 383 13.to 1.ALL we did was swapped the heads out for a new set of dart pro 1 230 plat's and picked up 3 tenths in the 1/4 ...10.70's to now 10.40's and they have no work done to them yet. :shock:
I personally think the -8 didnt flow what he was told and the port work was just a hogged out set heads that didnt make any power. :wink:
