How much street & how much strip? How important is OD? Why isn't a 4L80E on the consideration list if you want OD with high HP?

i got great prices on those two. The others cost a little to much as of now. Its more street then strip though

[Tru2Chevy]

I would go with the 700R4 if you're on the street more. As long as it's properly built it should handle that kinda power without much difficulty.

+1 you'll likely want OD for a street car. Make sure the TV cable is setup right.

Unless you want to put a TON of money into a 200, they are worthless. I don't care what magazines say it's great, they are **** unless you spend $3000 to upgrade EVERYTHING.

700r4 is pretty good unless you can get your hands on a turbo400 and enough money to make it bullet proof

No brainer. 700-R4.

A stock junkyard t-400 is better than a "built" 700r4...and it isn't all that much to make a 400 handle 1000+ hp......less than $2000 WITH a torque converter

add overdrive to it... theres your extra cost.

[badzracing]

4l80e with a manual tranny or hydraulic shift modifications are more expensive than a 400, but THE best option....bulletproof and overdrive....only drawback is that they are the size of a friggin jet-ski and weigh about 50,000lbs...at least that's what they feel like in 100 degree whether when you're picking it up by yourself

[JSPERFORMANCE]

What torque converter are you going to buy that will hold 1000+ hp? I only have a little over 800 and mine was like $1100. TH400 with a manual valve body, brake, pro mod drum, roller bearing conversion, ultra bell, and everything else can cost way over $2000 to build by itself.

But I am sure some dirt bag in a magazine you read dug one out of a hole in a junkyard in west virginia then threw some new frictions in it and now it is in a car that goes 8's for under $100 and a bag of Skittles.

Old Skittles are like ball bearings.....

taste the rainbow of HORSEPOWER

[badzracing]

Thanks for assuming I read dirtbag magazine articles, but my dad owns a high performance tranny shop and therefore I have a little tranny knowledge myself. I GUARANTEE you I can get you a 400 converter that'll handle 1200hp for less than $1000.... and a spragless unit that candle handle quite a bit more for probably around $1000.

Pro-mod drum? are you serious? You thought with 800hp you needed a pro-mod drum?
And this roller bearing conversion...are you talking about replacing all the thrust-washers with torringtons? That's a whole $50 "mod"......

I don't know who's doing your trannies, but I stand by my previous statement and can/will build one with a converter that will easily handle your 800hp for UNDER $2000...and it will be tested (on a dyno) AND guaranteed.

[badzracing]

If you want to start adding transbrakes/ alto and kolenes/ aluminum drums/ ultra bells/ different first gear sets/ straight cut gears....then yeah, the price would be quite a bit more, but a 400 doesn't need all that **** to handle a lot of horsepower. We have customers who have proved that for many, many years.

[JSPERFORMANCE]

By your own words your trans would have to built for under $1000 RETAIL core included. It is alot cheaper to build a hi-po box when all the parts are at your fingertips and you dont count your labor.

I never made any deragatory statements towards you personally so you have nothing to get all heated up over.

[JSPERFORMANCE]

I have people that I consider family that own a trans shop as well. In fact they build boxes for some of the best and fastest bracket/top sportsman racers in the country.

All I ask is that when you go throwing numbers around be they HP or monetary please be realistic or else you are just making everyone's job harder.

Forgive me if I'm mistaken, but he DOESN'T need a trans capable of holding nearly 1000-2000hp.

Given that his power ratings are modest and that it's a street car, I'd figure that that means no extra clutch packs or special valve bodies or even a really hot converter. Whatever will work reliably, keep the price down, and given the cost of gas keep him away from the pump as much as possible.

you are absolutely correct. feel free to clean up this thread if you like

Nah, I'll let it be. Not that big a deal.

Josh, I am curious though. What would you recommend?

[JSPERFORMANCE]

Depending on the application. If he is honestly going to keep it mostly to the street a correctly prepared 700 will better suit his needs, The overdrive will allow a steeper gear out back which will help with et while retaining some driveability when off of the track.

If it was more of a strip car with occaisional around town cruising then the 350 would be a more cost effective and simple route while remaining durable as well. Also the 350 has less rotating mass so that would help as well when it comes to shaving tenths.

I have a few th350s out there in street cars that run anywhere from 11s to 9.70s so they will definately hold up under power again if properly prepared.

Easy response:
mostly street=700
mostly strip=350

I only took it personal because you made it that way. You questioned my knowledge and whether I could possibly deliver on the statement/s I made. I will put one of our transmissions up against anybody's.

As far as the converter statement I made, that was directed to you, not to the statement I made about the TC and Tranny for under $2000.....I said the tranny would be capable of a 1000+ ( chances are that there aren't too many cars on here with that) and the fact that he said he will have around 500hp means he doesn't need a billet, all out race converter. After all I was talking to the original author who was asking for advice. The 400 subject came up and i offered my opinion on that.

I apologize to the moderators, and the author of this thread for hi-jacking it.
