I think there are aspects of EFI that compensate and surpass carbs for power output

We are at 12.4:1, so there is power left. Just maybe not enough to matter. We will find out when I get some time. Flying to Indiana this weekend and won’t be back till the Friday after. Maybe the following Monday.

Convinced myself that the converter needs some attention. THE car doesn’t spin much. Typical slick spin, just a touch.

Convince yourself all you want but a carb pretty close to being dialed in is going to out run the same efi setup everyday. I will say the efi is much better for a street car which is why I run it. But if I had a track only car a carb would be sitting on top of it.

the EFI was slower over the cabs best. But not aslower than the carbs typical runs for Mph. Just ET. It’s been a decline and in the trans I’m sure. Car is not picking up ET on a 150 shot. That says enough.

Starting to 60, key words. If you would have had the same mods with carb as you do to the suspension, and converter, the carb would have again been faster. I think efi can run as good, and definitely better for a street car, but I don't think efi can outperform a carb. Consistently, yes I think it can as in varying weather conditions but That's the only advantage in my opinion. You know what they say.....lol

Yea, this will never run as good as the carb did, but it will be close. It’s best carb pass on slicks is about 1 MPH faster so far on motor.
