3500 with no extra weight added.

I see 10.83 or .84 at sea level ;-)

Mark,

Have you had a chance to get this combo back on the track yet? I would seriously be interested in seeing two things. 1. What a ported intake would do. 2. What a modern lobe would bring to the table.

The week of July 13 it will be tested, I will let you know.......

Time for the rubber to meet the road, smooth idle 427 drag test Saturday........

7.09 @ 93.2 MPH, 1.53 60 horrible track prep
4520 DA
130 grains of water
27.86 Barometer

Well now... Good show, Marky

Re: I'm going to build a smooth idle 427 and drag test it
 

Heres what happened:

My car weighs 3720 with 140 pounds of extra weight added in the rear ready to race, I did not have the extra weight in the car which made it weigh 3580, but you have to take into account the iron intake, which probably put me at 3600. When you race at a mid west altitude track (2130) track in the summer you can ONLY expect horrible conditions, and it seems every time I go to this track theres more problems making runs, I need runs to develop combinations, thats why I drive 800 hundred miles round trip. So when you look at the conditions, well they don't look so bad

27.87 baro
130 grains of water
4500 DA

Well let me tell you, the 130 grains of water is the problem, and that becomes a tuning problem, especially when you have no runs to tune.

1st run spun the tires, run aborted
2nd run spun the tires run aborted
3rd run first round, dialed 11.49 caught the person I was running against @ 900 feet and door raced him to the finish line
4th run, time only waited and waited and waited to run until I had 140 grains of water, they just got done running all the power adder POS cars and finally they pulled me out, I had my tires set for a compromise to get out of the whole 19 PSI, any less they wadd up, I launch to a dismal 1.530 but hooked, at about 500 feet out I feel the car break traction, I pedal it and get back on it (remember the POS power adder cars before me) and run

1.530
7.09
11.29

So after this I was so pissed I put the car on the trailer and left. I knew going out there not to expect much, I would have been better running at Bandimere and correcting the the times, but your not going to get any runs there either, but you can expect the track to work, and you will not be working the water problem.

But you need to remember which I think most don't understand about this engine, it has a production camshaft, the exact same cam that came in your 1960s 350 HP 396s and 385 or 390 HP 427, but with 9.7 compression, what can you really expect from this smooth idle engine with a car with 4.56 gears and a 8 inch converter. I can guarantee with the right converter and gears run in the right conditions the out come would be entirely different.
