Well today I decided to put conjecture aside and numerous posts about shifting or other stuff related to racing and just bite the bullet and take the Coronet to the track. Guys I had a blast as always. First off most of the time I do these events with my buddies, but my wife wanted to come by and check it out, and have together time. The cool part there were hardly any cars there today. I bet maybe 20 total and most were door slammers, so lots of fun running it. I went to see what the open exhaust, new drag radials and to figure out my shift points. Here is my consensus. The car likes being launches at about 2000 rpms. It also performs its best at 5500 RPM shifts. Anyway, I got my new personal best which was 13.422 at 104, but still had an ugly 2.1 short time. The best part about this run, other then my new best. I totally treed this SOB in the Camaro. He was talking all about how he was dead eye on the tree and yadda yadda yadda! Anyway for your viewing pleasure (75) me------(37) Camaro dude R/T .256-----.789 60' 2.141-----2.127 330' 5.766----5.681 1/8 8.706-----8.607 MPH 84.14-----85.10 1000'11.257-----11.131 1/4 13.422------13.274 MPH 104.37------105.31 http://s13.photobucket.com/albums/a270/Mike440SB/?action=view¤t=20101010130516.mp4My second run, I actually am kicking myself at. I had a much better short time 1.9, but instead of leaving well enough alone I decided to shift the car at 6000 rpms, problem was I had decided first to put in my limiter the MSD digital 6 set up for limiter at 6000, so I picked up a nasty miss at the top end. I think if I would of shifted at 5500 like I had been doing then I would reset my new time. http://s13.photobucket.com/albums/a270/Mike440SB/?action=view¤t=20101010131735.mp4I'll say this, it was the first time I had been to Great Lakes Dragway in about four years and I thought the track prep was just awesome much better and was running smoother then it had been.

So, what are you asking?  104 tells me it'll run 12.60's or better with a loose converter and traction (it doesn't appear to be spinning)........What converter is in it? (it sounds too tight to me, on the video)........My recommendation is to be a Man  and have that converter loosend up to stall in the 4,200-4,500 range........ 
If you can't handle the truth, you're living a lie.......

Its always fun to go and run your car. Had a blast this year at various events & TNT.
Looking at the numbers, the 60ft either wants more timing or fuel. Based on the 1/8th mph of 85mph, it wants squirter fuel big time. Timing & overall jetting are good with that mph.
Still looking at 85mph in the 1/8th, you should be running 8.30's or faster, yet the mph in the 1/4 was low, and probaly a little lean on the top end. The difference is, I don't think its the jetting, but rather fuel pump pressure, or lack of overall flow.
Tinker with one at a time. The easiest is the squirter shot, and go from there.

Or he could keep the tight converter and hit it with a 150-shot and probably run in the 11's.

Great video footage of 'da Grove! It seems the track prep has improved over the years... if you get the chance to, Thursday nights are/were their 'heavy hitter' evenings where the big dawgs come out. I managed to get to a couple of those last month before they switched it over to 'Fun Racing' nights - there were some REALLLY fast cars out there. Was it a 'Fun Racing' day out there when you went? Planning to head back this weekend on Saturday now that my dana is in... It would be good to see both of ours run there sometime! Best of luck with your car, looks great!  Dave

Wayne your answer is always bigger converter!  I've got a 440/ hemi mechanical Carter on it. Where do I go from there? I guess I can play with the squirters on the Holley, but how much bigger should I go? Also, I don't think my bottom end would like a 150 shot right now. 67dodge I really enjoy GLD, but I got a few buddies who want to hit up Byron this week so that is where I will be on Saturday, but I'll hit you up before u go to GLD next time.

I'd say the same thing.
My guess, anything over 5500 is just killing it. I'd try anywhere from 5000-5500 and see how it reacts.
Work on the squirter and maybe play with a vac spring kit if you still have the avenger carb.
Car has mid 12's in it.
Cool to get out and run it. Enjoy it and have fun. Looks great!

Glad you had a good time. Can you post the details of the run with the 1.9 sec. 60'. Were you into the limiter in 1-2 and 2-3 shift? A 1.9 60' alone would put you in the 13.2s. I bet you had real good air. Personnally, until you can get your 60' time consistant, I would not change the squirter - presuming that you are on a street tire that you can spin easily off the line. Once you settle on the best rpm shift point (i.e. highest 1/8 amd 1/4 mph) I would suggest jetting changes with the goal of max mph. As long as your 60' times are all over the map, you cannot make any tuning or rpm shift point conclusions based on et.

If you want the car to ET well, I don't understand why everyone is so scared to try a quality, loose converter???  
What converter did you put in it? If I remember right, it was qutie a bit tighter than I'd recommended the first time???
I ALWAYS tell everyone that for max ET out of your car, you need a converter that stalls 800 to 1,000RPM lower than where you shift.......
Believe me, converter is where it's at...... About 10 years ago, I had a 3,910LB race weight '66 Belvedere.......With a stock stroke, pump gas 440, stock iron heads, small solid cam, 3.54 gears, 5,500 converter, and 28X9 slicks, it would pull front tires off the ground and run 11.60's @ 115 shifting at 6,500.........and I drove the car EVERYWHERE.......  That car was an absolute blast......Had a LOT of fun with it.......

Ok, so on that run I relly heated up the tires and let it go at 1500 rpms. I shifted at 6000 (1-2) and(2-3)rpms which was bad since on my MSD I set the rev limiter to 6000 rpm, so it began cutting out. So its hard to tell what is best for it.
Guys, this is encouraging, if I can get this car into the high 12's I may be the happiest man on moparts

I'm just teasing you a bit Wayne! You above everyone else has thought this car had 12's in it ll along, so I won't argue with the guru!
I do agree with you and we have talked about this a lot. My converter I guess is a tight PTC one that was set up for 3200 stall.
Here is the set up.
440 bored .40 over
9:1 compression
440 source heads
Comp Xe 268 cam
Headmen shorty 1 3/4 headers
Holley Street dominator intake
770 street avenger Holley
727 mMVB
3200 stall PTC converter
3:23 gears.
Open headers
Again thanks everybody for the help. I certainly had a blast! I know this car has 12's in it and plan on seeing if we can get there this weekend.
Mike
I know....... I'm giving you a hard time too...... Honestly, 3,800-4,000 is the LOWEST stall that I put into anything, even if it has 2.76 gears and won't ever go to the track.......
If you can't handle the truth, you're living a lie.......
