Hitting the rev

Hitting the rev
My car has a 400 trans with a 3.73 gear and it wants to get on the rev @ the 8 mile point. it did it three times, does it sound like converter slipping or wrong rev setting in the computer. spraying 100 from tha hit and 150 in second gear. the car was just computer tuned before i went to the track.

i'm running 1/4 mile. it has a 325 drag radial. and i know a 400 does not use a computer, i manual shift. rev is set @ 7200 on a 408ci motor. it has a ptc street/strip 3500 converter in it now and its about 6 years old.

Ok I get it now. After it is in 3rd at 1/2 track it is on the limiter.
What is the fluid condition?
Is the tranny new?
You may have a direct clutch slipping. And you may also be blowing through the converter. I recommend taking it to a Professional and having them take a look at the tranny.

it don't matter how you read it, i said COMPUTER REV, not computer shift. it's not slipping, it feels like a good pass when shifting each gear. i was just told it could be running straight through the converter on nitrous. don't know if it does that on motor because i don't run on motor.

Sometimes the written word can be interpreted in a few different ways.
Based on the last comments then I agree... it is "running straight through the converter" then that is probably what is happening. Especially if it is more than a few years old and has been hammered on.
What 60' times are you seeing with this combo?

I am going to go out on a limb here and say that your engine is 550 fwhp without the juice. 650 with.
I think the converter stall is correct, but is worn out. Swap converters, service the tranny and run it!

I get it, like a good buddy of mine who runs a 4oo shot on a Ford small block says....."When the **** hits the fan who is watching a tach anyhow, it either feels right and runs the number or it doesn't! "
I'm gonna hang with my comments and what your friend said... put a converter in it and run it. Then let us know how it does.
If you would like to discuss some options give me a call. We build racing converter and could put one toghther that you would be very satisfied with.

My shop is situated immediately next door to Xtreme. 15 minutes ago I was next door discussing a 700r4 build with Arvil for a mutual customer, they are building his LS1 for his '91 Corvette.
My recommendation, based on what you have mentioned here and without knowing the car would be either a 10" or a 9 1/2 converter. Because you spray it we need to put a balloon plate on it and tig weld all of the fins. There is no doubt in my mind that we can build you a converter that will get the job done. That unit would run right at $900.00. We can determine the stall later as we move through the process.
My converter builder is a racer himself. He owns an Altered that runs 5.7xx's, his wife drives a 2nd gen F-body that runs mid 6.xxx's herself. He is building a Vega with a 502 Shaffrof engine to run in IHRA Divisional Stcok Bracket classes next year.
When it comes to racing converters. We get it.
Lemme know if you are interested. I'll be here until 7:00 or so tonight if you would like to call.

arvil told me a shop next to him rebuild my converter for $400. the converter was never touched. i called him back later after i drove the car and asked about the converter he said it was done so i left it at that. they build me a iron block 408, but could not get the car to idle. i own the black 98 firebird.

Well I am glad to know that.
When was this done?
When you say it was never touched, please be very specific. Does that mean that the converter was not sent out by Xtreme? Does that mean that there was no difference in the performance?
Honestly, I do not remember your car, mainly because I see too many, but I believe that my shop did not do any work on yours. Maybe the converter.
PLease call me. I am at the shop now. I would like to discuss this matter in detail with you. I know of no converters that my customers are disatisfied with. If we built it originally and the stall is not right then all we ask is for the customer to get us the converter and we'll adjust it at no cost.
We need to talk.
