I see you are, just when I thought I was going nuts... I can't find the article too save my life, it was a pretty in-depth write up. How much more punch does it have with the larger center carb? its quite noticeable, even more so when your just driving around off the center 2 barrel. never done a back to back at the track, probably should try it sometime. 68 Dart GTS "HEMI" 10.30 @ 131 pump gas street car 3780# 69 Roadrunner 511 six pack 10.92 drive to track street car

Also he only took the motor to 6k. As I mentioned that thing should be making power well above 6k. Does he have an A/F meter on it? Did he monkey w/ the jetting/springs/squirters?

So after the dyno session are you saying the tuner left about 40hp on the table ? he sent me his dyno sheet, and after looking and listening to the video it seems the engine hasn't been tuned for best numbers. It makes peak H at like 5400rpm. It falls off well after that. I would think there would be more in it.

It makes peak H at like 5400rpm. It falls off well after that. I would think there would be more in it. I agree that the Dyno session was a little scarey with the motor jumping around like that at low RPM, the outboards were opening way to slow ... I hope the head gaskets survived that shock ... and there may be a LITTLE more in it but you are not realizing 3 things, it's a 4.5" stroke, the heads are too small for the cubes, and it's a HYDRAULIC roller cam, it's not going to be happy revving to the moon. When I originally talked to Darren about those heads he was putting them on his 440, that grew to a 493 when he pulled the trigger to buy them and they would have been fine on that, now add another 50 cubes, things change ... We had the Engine masters engine on the dyno and found another 30HP, but half of it came from changing the malfunctioning carb.

So after the dyno session are you saying the tuner left about 40hp on the table ? I don't know if I would blame it on the tuner, but that last vid didn't sound real good. The buck of the engine seemed like a backfire into the intake. Even under power it didn't sound like it was running smoothly. Sounded like it was still having some mini backfires trying to occur in the intake. I wouldn't be doing any high fives from that Dyno run. Id be saying, what the Hay. If its running as bad as it sounds to me, there could be 40 HP left on the table. Its not running right IMO

I know there was complaint years ago about core shift with the molds. Question 2, the slight stumble before the outboards pop open could this be reversion in the intake? The engine wants too pull but its sucking threw a straw as the rev's build the outboards kick in and the air velocity looses momentum before it picks back up again? So with that thought it seems too want air would a larger center carb get it over the hump before the outboards kicked in or would this just move the stumble higher up in the rpm range? #3 The jetting seems pretty close too the bone at 540ci, I would think it would like some more meat too eat on.

I didn't mean to take this thread in the direction it has gone, there may be a few more ponies in it but the real test is once it's in the car and running. I haven't seen the dyno sheets but I assume the AFR was close to being correct or it wouldn't have come off the dyno.

Any thoughts on what works best? now I know why my buddy asked me "are you going to work the intake before you put it on?" are they really that bad? How much more can you pick up? Mine is right out of the box.
