Anyone running a Stree/Strip 9 1/2 Dynamic converter

Thinking of bitting the bullet and upping for a better converter than what i got. I know abodyjoe runs and loves his. Just wonderin if anyone else is? :thumblef:

Thanx

Your doing good at 5100 feet!!!!!!!!!!!!! That converter would help, I would put money on it!!!

haha, yea its doin alright. I wont be happy until i hit that 13sec point at this elevation. That would be pretty good for my d/d 318 powered, full weight barracuda in some thin air lol. I have some weakkkkk leaf springs and air shocks right now. I have some superstock springs and summit drag shocks on the way to help that out, and also the converter i will likely order monday. My 60ft didnt change one bit going from 28"tall 275/60 radials to 26x10 Mickey T SLICKS. So somewhere in the tuning and converter I'm not quite dialed in. So both are getting some attention :thumblef:

I have one in but haven't driven the car yet. After talking to them and four other converter 'pros', I have complete confidence in it for my set up. Will let you know though.

You been runnin' that thing at Bandimere? I didn't think Henderson NV was that high. I was thinking more like 2200' but even at that you are running great.

Density Altitude my friend. Makes 2,100ft tracks have 5,100ft air (depending on the weather). :wack:

For your reading enjoyment lol

disregard the chevy link, info is good though. :thumblef:


You can see the first about 20ft or so it just leasurely walks off the line...then it gets goin. That converter swap should definately help, against a modded 340 challenger i think he had ported heads, cam, single plane intake, same stall, manual valve body, 3.91s, and drag radials. Not the best run of the night, 14.3 was, but i gained the time in the 60ft and it followed till the end.

just got off the phone with dynamic my *cough* $650 *cough* converter is gettin built as of now, 3800stall. :D

Wooooow

Wooooow


Took me about a month to ponder spending that much on a converter. From EVERYONE i've talked to it will be money well spent, I've yet to hear a unhappy customer. So I'm hoping it will do what i want and then some. :thumblef:

Don't even want to know what the density altitude is at the track here. I am sure it will make me want to be on oxygen.

If the info i found on your town is right. its 9:30 here in vegas, your d/a right now is 8578 feet :rambo:

Yeah a good converter isnt exactly cheap, but after kicking myself everyday for three years for cheaping out by buying KB pistons instead of forged, I refuse to let money be the factor in having a reliable, long lasting, powerful rig.

I hear that when i put the bottom end of my motor together. Live n learn :thumblef:

Cough cough choke!!! Where do you get the d/a info?

mines being delivered thursday.... i'll kep ya posted... just to put it into perspective, a fellow who runs in the quick 8 around here with a turbo on a small block chevy puts down 4 grand for a converter.... 650 donbt sound too bad anymore ? does it?

true, you ready to put it in once it gets there? im definately curious on how it does

Got one in the boys Dart and we love it. It drives so nice just like a stock convertor thats just right with the MP .557 cam we have in his 400. But nail at the track and she flashes about 4200 and launches great. Very steady 60's of 1.61 and 1.62 every pass. I like it so much I have one sitting on my workbench ready to go in my 63. I paid $595. for each. Ron

Cool deal! Wish i could pull 60fts like that lol. Sean at Dynamic said it was a little extra to make the 904 converters. little more labor intensive. I just looked at my online bank account...they charged me for a converter TWICE :cussing: now i better call in the morning :wack:

I'm sure they'll fix it up for you. Best customer service I've seen since I started buying parts for my car three years ago.

Good to hear the positive review!

oh and Ron, do you have any before/after converter swap time slips? Or did it just start out with the Dynamic? thanx

I have an original Dynamic, when Frank was in New Haven CT, and 2 customers of mine run the 9 1/2 convertors. In fact, Sean just turned one around (lowering stall and tightening it up a lot) in under a week. Very nice guy, and the convertors just plain work. It was pricey tho. The original cost of the re-stalled one was $650, and the new pump shell and stall adjustment was $350 more, plus shipping...

just met sean last night - first class guy, we met so I could save on shipping.

it'll be a few weeks beofre I get timeslips, but I have all my original data, so i'll get back to this thread with results. best 60' time is 1.93 - best et 12.80 best mph is 108, but that was alot colder out then, when I ran the 80... usually in the summer it will be in the 12.90's

DJVCUDA, make sure you keep it corked up this time! :) That was a nice writeup on the street machine shootout, and it's too bad you couldn't have gotten a couple of more runs in before you hurt their ears with the open pipes. :burnout:

No data to compare Jr's Dart to. When we went with the 9.5 Dynamic we also took the 383 out and went to the 400. It had a Turbo Action 10" tight 3000 convertor behind the 383 and it ran 12.31 @ 110 but it was basically a stock 383 with the .484 cam and 452 heads with mild port work. It did a best 60 of 1.77 like that. Course now the 400 has 10.2 comp (383 had 9.6) and the .557 cam with stock Eddy heads. It is the same intake , carb , dist , gears and springs on the car now and best 60 with this combo is 1.61 on a 11.55 @ 116. I deal with Sean everytime I buy a convertor. He knows me as "Ron from Balt" and I have bought 3 convertors from him myself and my brother has bought a few also. They work perfect for me. Ron

the weekend after the mag article went down, I went to atco, and was allowed to open it up for a 12.80 @108 run.... dont get me started with e-town.... what kinda racetrack dont let you run open headers~!>!!?!!?!@!@?

I feel your pain bud! :) Why bother with headers if you can't run 'em open at the race track? 12.80 sounds pretty good for the combo you have there - excellent! Keep flogging on it and you'll do even better.

thanks... i got this dynamic sittin in the garage, and a rebuilt tranny on the way... I CANT WAIT!

You've got a 904 in there don't you? Do you know what year the tranny is? I want to put the 904 back behind the 360 in my Valiant this time, but it's a 66 and I believe there's some small differences between the 66 and the later ones which makes it difficult to find converters for them. Good luck with yours, and don't you just love waiting for one part when you have another new one ready to go. :)

i might be wrong, but the early ones had smaller input shafts, you can either change the input shaft, or get a newer tranny. i'm not the expert on that tho...

the tranny I have in there now is from my 68 cuda, and sent out a low gearset 89 tranny to go in next with the dynamic.

Thanks. I think you may have hit it with the input shaft size. I remembered something was different but couldn't quite remember what. Old Timer's Disease. :)

got the dynamic in a few days ago...


WOW! what a difference, puts the car upin the powerband right away...

I could never spinn the tires and make the car go sideways from a 30 MPH stomp...with the caps closed before!

cant wait to get it to the track, right after carlisle!

i'll keep ya updated

cool deal! still waiting on mine, hopefully be here tomorrow. my current converter is just not cuttin it. Take off from a slight roll its real tricky throttle/car speed to get the dang thing to flash.most of the time it just bogs down like it does at the track. Cant WAIT for that dynamic to get here and in.

Well, the restalled unit is back in the car, and seems to be dead on stall wise what we ordered. I'll know more when the wheel studs are in and I can drive it, but it felt good breaking in the new gears and playing a little in the shop.

Density Altitude my friend. Makes 2,100ft tracks have 5,100ft air (depending on the weather). :wack:

Ever notice no one ever mentions the...."Best ET _ _. _ _ at unreal freakish once in a lifetime mine shaft conditions"....just an observation :lol:

I used a 10" Dynamic in my 70, 440 Cuda. Worked great. My 69 has a 8" Turbo Action that also works great and is 20 years old.

Ever notice no one ever mentions the...."Best ET _ _. _ _ at unreal freakish once in a lifetime mine shaft conditions"....just an observation :lol:


Theres a huge difference between 5,000+ ft and saying 'what it would run 0 ft when all the moons align'. Are you saying that if i went to say....texas where the d/a is about 1,700 this time of year i wouldnt do better? :poke:

You high altitude guys are always making excuses....;)

Easy to say from down there ;)

My tounge-in-cheek point was no one ever mentions the "0 ft. perfect aligned moons" conditions of a best ET/MPH. If anything gets mentioned it's "13.05, bad air, spinning, old gas, and the extra weight of 2 grande burrito's I had for lunch (Subtle message..... it's REALLY a high 12 second car). Relax, not a dig on your car, just havin' some fun. :) :jocolor:

BTW, the 9.5" Dynamic is a great converter! In my old 360 crate motored Coronet wagon I went 12.49 best (in cool weather, tail wind, fresh gas, national event quality prepped starting line and fresh off a 50 lb. weight loss from the Adkins diet) :lol:

wish me luck! converter is due to go in tomorrow, id start tonight but i have to drive to work lol. I'm puttin it in bright n early tomorrow AND at 5,000ft d/a! lol

New converter is in. abosolutely awesome so far. been outdriving twice. from a dead stop is no comparison to the old converter. Looks like there is a track outing the 21st and the 11th. 21st is a joke as far as cars, 300some odd cars, huge lines, ricers draggin water to the line. 11th is much better track prep/more passes. i think im gonna suck it up and have to wait for the 11th lol. oh its gonna kill me.

I want to see some 13's from that little 318 :headbang:

Shouldn't be a problem. At 5,000ft lol

Ok...so..it's the 13th...How'd she run?

Sorry shoulda clarified

New converter is in. abosolutely awesome so far. been outdriving twice. from a dead stop is no comparison to the old converter. Looks like there is a track outing the 21st of July and the 11th of August. 21st is a joke as far as cars, 300some odd cars, huge lines, ricers draggin water to the line. 11th is much better track prep/more passes. i think im gonna suck it up and have to wait for the 11th lol. oh its gonna kill me.

LOL..oh...sorry. I should have known. In the meantime, practice your launches and burnout techniques.. ;)

got mine in - lol you gonna love this line - CONDITIONS WERE HORRIBLE - but i did get a new best 60' time with the dynamic.

previous best was 1.93 - november air - 40 degrees, moons alined, correct angle of the dangle...etc
new best is 1.88 - 85 degrees, 100% humidity, bad track prep, blah blah blah... but i did get a good 60'

most guys were off thier best by 1-2- 10ths... so I am VERY hapy - i would have been in the 2.0 60' area with the old converter!

here are 2 pix... before the dynamic... in november, moons aligned....etc

and after the converter....
you can see some sidewall wrinkle and more front end rise! but bad conditions!

I'm running a Dynamic 9-1/2" and I need to send it back. It's too tight. I need about 800 rpm more stall.

Anyone have a problem with there's (specifically the converter bolts) hitting the top edge of your dust cover on the bellhousing? I didnt think my cover was bent but dang did those bolts snag the top lip.

i had that problem before.. i think its the 7/16 bolts just catch the lip of the shield..
