Looking at maybe changing converters, current one was built by a friend 25yrs ago. Its a 8 inch and he refreshed it this spring but I feel its holding car back, it should be mph in the 130s and so far has only gone 126. Feels like its on a dyno all the time, never pulls rpm strong.

Who makes a good 727 converter in the 55-6500 stall range. This is for my AMC but there is really no difference in converter but the ring for starter.

What ET does it run?

Could be slipping.

i would call Lenny at Ultimate Convertor. I got one from Lenny last year.

I gained 2 mph, 3 tenths, and my 60' jumped to 1.55 from 1.70.

I changed nothing else but convertor.

that mph seems about right for the ET. my car is only 60ing in the 1.5 range but I blame it on the 3.55 gears. I have the same converter that was behind the big block. its a 9" from Lenny at Ultimate

Not so worried about the 60 foot but that it wont rpm right, always seems like its loaded, never two strokes or gets on the cam. Also mph is low, the 1/8 mile times and mph are better than at 1/4. This engine should be pushing it to 133 or so.

starving for fuel maybe. your jet change didn't do anything. maybe its not the converter

If you think it should MPH at 133 then you should also think you should ET at 10.0 or better.

Exactly, I can find the et once the mph is there, engine should be capable, its 12.4-1 heads flow in the 360 range and cubic inches at 436, tunnel ram with two dominators, cam is .794/.746 278/286 at .050 on a 110 center. even if the combo is wrong and doesnt 60 or et right when it comes on it should mph out the back and its just not. Old iron headed 401 with a flat tappet was running 11.2 at 122 with same converter, had been in car for 25 yrs and then et dropped to 11.7 and 118 so I thought engine was tired so it came out and new one built. it still has same issue so I think that is where its at as drastic tuning changes really make not much difference.

you should be running 10.0-10.10's with your combo.

I ran 10.85 @ 126 mph off the trailer, no tuning.
436'' w2 heads, 13.1, tunnel ram with 650's, 660/632 lift and 277/288@.050. 4.30 gear, 28'' tire. 3800 lbs

first thing I would change is convertor. i picked up with my swap in convertors. my car felt sluggish and i knew it had a lot more in it.

Did you get my pm? With that cam and head combo you should be solidly in the 9`s unless it`s a heavy pig AND that`s w/a Continental vert.........

Guess this is an example how "easy" n/a tuning is.........

Yes I got your pm, thanks! and yes it kinda is a heavy pig (3500) but it should still pull on the big end. Hell last yr I took out 200 lbs and didnt really make a difference.

Dont know, the wideband took a crapper when the battery and msd exploded never have had a chance to check full throttle readings. They are pretty close as far as plug readings go.

First for a race converter, I've been very happy with Lenny from Ultimate. Second, I ran the N/SS 10.50 index for years. The numbers when the car was set to go 10.50, 1.45-1.47, 6.70@103/104, 10.50@127.
I'd say your numbers line up. with a 4.44 and 28" 6900rpm is pretty decent for slip. I think it's down on HP.

Yup your right I don't have to worry about a converter with my nitrous car just use a stock one! Lol jets in carb don't worry just add jet to the nitrous till it runs better!

On a serious note call Lenny and give him your specs he will fix you up. I have had a few convertor problems tci and dynamic so I know what you are saying.

I agree to a point but the better tuned n/a the better on spray. A friend of mine has a mid 8-second street/strip small block stroker mustang and I`ve been at the track w/him before he made some suggested changes to get the n/a tune sharper and sure enff, he`s been his fastest ever and even won three street car shootouts back-to-back.

Guess this is an example how "easy" n/a tuning is.........




Yup your right I don't have to worry about a converter with my nitrous car just use a stock one! Lol jets in carb don't worry just add jet to the nitrous till it runs better!





I agree to a point but the better tuned n/a the better on spray. A friend of mine has a mid 8-second street/strip small block stroker mustang and I`ve been at the track w/him before he made some suggested changes to get the n/a tune sharper and sure enff, he`s been his fastest ever and even won three street car shootouts back-to-back.




My point exactly, just because we have a power adder car doesn't mean I don't have to tune my car just like a na car. The better the tune the better it will run, wether it's a carb, fuel injection, or a convertor. It's all the same just as hard to tune, doesn't matter if it's turbo, supercharged, nitrous, or na.

I wasn`t saying nos or turbos are the end all on their own cos tuning applies to all motors power adders or not but a lot of guys I know seem to think they take care of a "bad tune" or a "tired" motor and it`s just not true and that`s why "these" guys have constant problems and aren`t as fast as they should be.............

Not so worried about the 60 foot but that it wont rpm right, always seems like its loaded, never two strokes or gets on the cam. Also mph is low, the 1/8 mile times and mph are better than at 1/4. This engine should be pushing it to 133 or so.




Your 1/4 mile Et and MPH are right on.

Your 60 ft.s are off, so I would work on that first. Your 1.51 60 ft. is a 11.20 ET indicater. So your MPH isnt low at All for your ET.

It may be low for your engines expectations, but its not low for its ET. Your 60FT. times however are low for your MPH and ET.

Get your 60 ft. times to match first, then worry about what you think this engine should be pushing ET wise. One thing at a time.

EDIT. If you think it should MPH @ 133, then It should 60 ft. @ around 1.39 or below.

This is a street car that weighs 3500 lbs with no trans brake so I would say its ok. It is dead consistent but the et its running can be done with much less engine so I want to find out what the problem is, if its engine then Ill adress it but this is already the second one, first started acting the same so I assumed it was tiring out.

I see this a lot and the first thing I do is give the motor a cranking comp. test or leak down your choice, then go from there. If you have a hurt or wounded piece then nothing will help. Then ign. test etc. Then of course converter. Did you flash test you vert?

Leakdown is good, compression is where it should be for camshaft timing etc, all looks good, ign phasing and timing checked, different boxes and tachs, checked fuel system and changed, all with no effect. Flash test was to 5500 in 3rd. My process of elimination has led me to the converter or maybe a trans issue, sprag etc, dunno. I appreciate the opinions, keep them coming.

I kinda get a kick out of this statement. Your 60 foot time is the most important part of the run whether you are a bracket racer or going for a "new best". It all starts right there and the rest of the run is the easy part.


1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27

I realize that but Im more concerned with where the mph is right now, The 60 ft and et will come later. Obviously I should have engine dynoed it to know where it should be but I have a friend with the same basic build, has 11-1 compression, smaller roller cam and a sinlge carb and car is within 200 lbs of mine, he is trapping 135, he has chassis issues keeping his et at 10.20 or so but it is showing good hp. That is what im looking for is lost hp, not et right now.

Car has ladders and single adj qa1 coils.

Maybe the t-ram is the problem because I always hear about single carbs and intakes out performing t-rams these dayzz.......... Comparing different combos isn`t always accurate anyhow........

These intakes are amc only and usually show 40-60hp over singles most of the time, the indy amc intake is really not that good and is what he has. I have thought of putting the single on to try it but, I like the duals lol been on there for 30 yrs. The reason I think its conv is the last engine was down 5+ mph also, I just assume it was the tired engine.

What west coast cars does he do? I like to try new things but Lenny has done good by me. I know of a few heads up cars around here with ptc and digby dental uses them in his dart. He went 4.9s with caltracs and there conv, so it's made me think about them.

Most of the fast guys that street race out here(can`t mention)use em and some are in the low 8`s high 7`s plus some pros including p.s.c.a. guys which was my point. These guys drive their cars, spray and turbo the hell out of em and they`re still goin strong but I`ve heard great things about your guys to..........

They were some of the finest converters I used when I was running door cars in the 3200lb range. That said, I would suggest putting a single carb manifold with one dominator on it. Hopefully you know someone that has one. That sounds like a ton of CFM for a small engine. JMO It's not to say that you can't run two, but it would need to be in the 8500RPM range with a very loose converter, like 7000 stall. You should be running a very loose 8" converter.

I do have an intake and carb, just every time I tried in the past it was 2 tenths and 3mph slower, my dominators are the 750cfm ones that are basically a 2 circuit 1050 with flared boosters. At this time I think they have too much signal as I have to really lean em out to run good afr. thought about even changing them to straight boosters and make em 1050s as most of the guys I know are using 1050 and 1150s with great results.

So you ran your old motor with this intake and then it lost mph, you replaced the motor and you still have bad trap speed? You have changed a lot of other things with no change, I would try a convertor.

Looking at maybe changing converters, current one was built by a friend 25yrs ago. Its a 8 inch and he refreshed it this spring but I feel its holding car back, it should be mph in the 130s and so far has only gone 126. Feels like its on a dyno all the time, never pulls rpm strong.

Who makes a good 727 converter in the 55-6500 stall range. This is for my AMC but there is really no difference in converter but the ring for starter.


Nothing else but the highlighted should matter here. TRY a converter. Some things may have changed in 25 years.

Tony,

I sent you an email. I picked up a little over .2 and 2mph switching to ATI from the same converter that Tony is running.

Later,
