New track times...still not happy

What are you running for total timing and what distribtor? Also, could you post all the timeslip data? Like 330', 1/8 mile &MPH, 1000', etc?

I ditched my Carter 625 for a holley 650DP and the car dropped 3/10ths and a total of 6/10th when I got a handle on the jetting. Walk through the pits, everyone fast has a holley or a demon carb, there is a reason for that. Look don the airhorn of the holley versus the carter-no doubt as to which one is going to have smoother flow into the engine. I would try and get a few more tenths out of the current combo (minus the carburetor) before switching heads.

Lose the heads. Check into the converter like the other guys are telling you, not much of an automatic guy here, so I'm out of my element on that. I had a 750 Holley with a ProForm main body, and it was awesome on my little 302. Hoping to use it with the new engine, but my desktop dyno says NOPE. Gonna try it anyways, but I got an 850 for backup. OVER carbing is worse than not enough, so see if one of your buddies has a 650 you can try. Do you have to use an adapter plate with the Carter AFB? If so, that's not helping either.

Anyways, don't get frustrated. It's a long summer ahead. We'll get ya in the 12's before it's over bro!
