Went to track today and car ran great but I couldnt cut a light to save my life. I would have won two rounds in a row if I could cut a light. Seems my car isnt reacting off the line as quick as I am. I think I need a 3000 stall converter with my car. Its a 340 with a .484 purple shaft cam and .284 duration and my cars seems slow off the line . My 60 foot times are 1.95 to 1.97 and I know the car has more then that in it. I ran a 8.74 at 79.8 miles per hour . The guy I bought it from said it had a 3000 stall but I dont see it. I have 27 inch tires and 3.91 gear , what do you guys think about it being slow off the line. I think my 60 foot times could be 1.7 and run at least 8.3. Thanks guys and if you have a good used I may be interested . If not what should I buy or not buy. I wanna keep car streetable

80mph is ~ 8.50 et. Decent 60's in mid 1.8 for the same MPH
What's the tach go to when you mat it before picking up RPM.
A good converter makes a world of difference. A good converter that flashes into the very high 3's to low 4's would wake it up. Make sure the chassis is working, no spinning.

You mentioned keeping the car streetable. A high stall converter will help you get off the line quicker, but from my experience, it will also kill any fuel economy you had. So, that's one trade off you need to consider.
Its not spinning at all . What brand of converter would you say is good, I know there is going to be more then one. Not sure what rpm it jumps to right off hand . Do you means when Im at the light and hit from the foot brake. I will check tomorrow but I dont think it really jumps at all and I think if it jumps thats where it flashes right. How high of a stall do you think I need , Im thinking in the 3000 range. I think my car has more in it then 8.74 Im thinking 8.3 to 8.4 . I think my 60 ft is off a few tenths for sure.
I dont really care about fuel economy right now. Car wont see a lot of street time this yr due to the exhaust and such mostly just to and from drag strip. Its just seems to be way to slow off the line and its doing well on the other end at almost 80mph with a slow 1.98 to 1.97 60 ft

Call PTC. I can't remember their number. I can get it for you since I'm calling them this week to order mine stall. I'm running 8.3s and 1.97 60ft times. I'm spinning drag radials. They told me I would cut .4 off my 8th

You will hear a few names that are good and most of them will be right.
Converter technology has improved to the point where a 4000 stall converter is perfectly streetable.
The loss of efficiency is no where near what it was when the hot tip was a Vega converter.
10 % slip in high gear is the standard.
I used Lenny at Ultimate and we came up with a 9 1/2 " that should stall in the mid 4000's for my deal. A street / strip small block car.
PTC and Dynamic are both reputable.
The thing to remember is that a 300.00 converter is not the answer.
Expect to spend upwards of 600.00 for quality.
But it is well worth it compared to a bargain converter.

Cool man whats your combo and what drag radials are you running. MT Streets are really good I got friends with ls1 cars and stock suspension running 7.50 or lower with them
I put a FTI converter on a ls1 car about 3 yrs ago and it almost knocked .5 seconds off my 1/8 mile and drove close to stock. They are billet also and great to deal with. It will cost around 665 bucks for it but if you have a 10 inch or smaller converter they will give you a 200 dollar credit

a good converter will make a huge difference. i think i would drop to a 26" tire too.. my dart would go 1.63 sixty foot times with a 3.91 gear and 26" tire. the 284 mp cam will want at least 3000 stall and at minimum 3.91 gear.
personally what i would do is call a good converter company dynamic,ultimate ot ptc and get them to build one to your combo and intended use.
i had dynamic do one for my dart. it was a 9.5" that flashed to 3800 rpm but was totally streetable. actually felt like a stock converter on the street. could easily sit at the starting line and get 3000rpm out of it just on the foot brake
i let a friend drive the car after i changed the converter, he came back white as a ghost and said what the hell did you do to that thing? he couldn't believe that all i did was change the converter. it made a huge difference..
even with stock 100,000 mile slant six springs and air shocks and old worn out front suspension it would go 1.69 sixty foot times..

Im gonna call one of the companies for sure tomorrow. I may go with FTI out of florida as they have made one for me in the past and it was awesome. Im staying with the 27 tires as they were brand new as of yesterday and I dont have 500 to get another set.. What is the most popular converter on this site

maybe in 1970 or some off the shelf cheap garbage out there .. new quality converters are very efficient and most times will be tighter on the street then some garbage tighter converters..
My FTI converter drove like stock until I dropped the hammer and wow

seems most go with one of the three i listed. (dynamic,ultimate and ptc)
the biggest thing is to be 100% honest about your entire combo and intended use..

exactly...
PTC seems like a good price for 9.5 converter at 475.00 but FTI has one for 655 and it is billet. FTI says if you have a 10 inch or smaller converter they will give you a 200 dollar credit. Not sure what size mine is but prolly 11 inch .... damn it

i'd call all of them plus the one you already know and see what they say. can't hurt to get different opinions.. go with the one you feel most comfortable with..
i paid like $600 from dynamic. that was quite a few years ago now.. may have gone up..
the $200 credit sounds good..

PTC is building mine for 475.00 and you are correct about being streetable. They said it would stall around 2k normal driving and 3000 to 3200 when getting on it. The reason I like PTC is they are a hour and a half away from me and do good work.
I'd pay more to Lenny at Ultimate or Sean at Dynamic than the other one mentioned.
Dynamic was having a $595 sale for their 9.5 converters recently.

Just picked up a Dynamic 9.5 with B&M flex plate for $200. Can't wait to try it out.

I just installed a dynamic 4200 / removed a 3500 converter I put in so long ago I can't remember whose product it was , with the dynamic the drivablitly on the street is awesome an I am pretty sure I dropped about two hundred. Rpm when in high gear
Abody up what rpm are you pushing the engine to before you flash it pretty awesome seeing the left front coming up
