It ran 10.53 at 126 in bowling green this fall at drag week. 1.51 60, car weighs 3500lbs, 4.44 gear and 28 inch tires.
Being it was HOT down there thats what the HP shows for that day... the ET and MPH is right in line so thats what it had for power that day.... what was the A/F ratio that day
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. Doug

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.

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.
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.
