another sbc intake question

[prostreet34]

427 c.i. sbc
215cc dart heads
248/254@50 .576/.582 solid roller
10:1 comp.
3.73 gear but has 33" tire (I may need to put more gear in it)
have not ordered a converter yet (any suggestions) would like to stay under 3000
car weighs 2600 lbs.
street car only, will see very little strip time
good internal parts, planning on turning motor 6,500

should I use darts dual or single plane?
Trmnatr your post in another thread was helpful
Because of c.i. and light car should I go with open or just stay with dual plan?

[lun40119]

I think single plane, and an ATI 10". JMO

[Trmnatr]

Dart single plane if using a 5,000-5,400rpm 8" ATI stall

If not use a 4,500rpm 8" stall and a Dart dual plane or RPM airgap

[Awesome Bill]

You do not want anything over 2800-3000 max stall. You will burn your high gear up if you do. This is a real street car here not a drag car. A good 10" TSI XHD is what your after. The single plane manifold is also the choice here up to 6500rpm, the dual plane gets lost around 6000. You put a 8" converter in this thing and you will have a messssssss!

Thats strange bill

How do we run a 6,000rpm on the street with no over heating issues ? We have ran a true 4,500rpm stall for a 65 mile round trip with no issues

But we use ATI converters which in my opinion are the best for a high stall on the street

I know 5 true street cars running 4,500-5,500rpm with zero issues

[prostreet34]

Thanks for the input guys. Going to look into ATI or TSI XHD 10". I drive the car
way to much for a 8" converter, once in a while interstate 75mph 2-3hrs. at a time.
I have had big block cars with 4000+ stall and had no problems but I drive this car alot more so I would like to stay under 3000. I guess I was looking for brand more than anything.

Leaning towards single plane intake, just thought dual would be more responsive and practicle for the street but I didn't know if it would support
427c.i. @ 6500rpm. Don't want to leave to much on the table.

thanks again

In my opinion dual plane just because of the torque converter

[want-a-be]

On that inch plus the desired RPMs, I'd go with the open. It'll support it better. But mainly because I just don't like duel plemun intakes.

Going to drive my chevelle to Bristol in June on the Power Tour with a SBC, a TH400 and an 8"ATI. Not too sure on the stall yet, until after the dyno time bout should be around 5000-5500. But I do agree, a 10" is probably a better fit for you. Car would probably ET with the 8", but oh well.

[Awesome Bill]

really drive it in street conditions, especially in traffic. You take direct right out of it especailly without a external cooler. If your cruzing @ 3000 rpm and you say you have 6000 stall, that is over 3000 rpm of slippage, just he heat from this especially with a car over 2800 lbs is a no no. Ask Jim if he recommends it and he will tell you not for the street. Everyone is the torque converter business uses the exact same stuff!

[lun40119]

I don't cruise at 3000. And I monitor trans heat in the outgoing line with a mech guage. Seems to be working for me. Change fluid twice a year, and I think it is actually cleaner than when I dump it in ;).................have you seen my Playdo.

[Awesome Bill]

Once again, real street cars here not drag cars run on the street a couple of miles a time. I guess you have a/c, cruise, 3.55 gear and a 32" tall tire! I build tranny's and that much slippage works on them very fast.

[lun40119]

This is a real street car. Last year I drove it from Sturgeon Bay WI to Appleton WI, with 4.56's, and the 5000rpm stall. Never let it get below 4000rpm, with a bunch of pulls to the limiter. I am not saying it is an ideal street cruiser, but it gets the job done. This new one will be driven to Bristol on the power tour this year too. If I HAVE to trailer it, I don't want it.

[Awesome Bill]

Most likely very light, under 3000lbs?

[lun40119]

3520 with me.......Vinyl buckets, back seat, its all there. Even the big granny steering wheel. We have a scale at work, I weighed it last fall to order the converter to go with this new engine.

[Awesome Bill]

My 68, that runs 7.86 @ 175 is also a real street car. Not leagal any longer but still puts a hell of a 8.50 up that wins. I drive it to the cruzins if I like but most of the time, its really my 8.50 street car. She is only 3300 with me, my 10lb bottle after 1 run and ½ tank of race fuel.

[rbrduck71]

torque converter i mean voodoo magic

i used a 35-3800 in my 1300 pound car i made my choice by saying in front of an old

drag racer i think i need a 28-3200 stall and he said that light a car and the stall

rating changes, he said i need a higher stall to get the lower rating in a light car,

is this right?

Hey I am going to drive mine to a cruise in too.....in Bristol from Madison WI. You are right though, it is slow. You know 630 horse small blocks. Crap, I see at least 2 dozen 600horse small blocks at every car show I go to :D :D :D. I suppose if I had 500horse of nitrous on top of the 600+ there is now, it would go quicker.

Dont get me wrong, I know your camaro hauls the mail, I have seen the Etown vid, but that doesn't mean that I built a piece of crap. It does have an ATI 8" converter that stalls around 5500, and I do put 6000+ miles on it a year. And it has had the same Hughes Reverse pattern 400 w/ a brake for the last 4 years. It can be done, just put a big cooler in it.

[SUX 2BU]

Just a question here from a guy who hasn't had a vehicle with any kind of high stall converter in it: how much does a 5500+ RPM stall vehicle wind up before it gets going say when you are just pulling away from a stoplight? And secondly, how do you stand 4k+ RPM of highway cruising for extended period of time? lol My truck with 3.40 gears and 27" tall tires revs around 3000 at 65 and I find that a little much. If it take it past 3500 on the freeway I feel I'm going to hurt it lol

[lun40119]

My cam really doesnt' smooth out until 3500. It is kind of loud, but I have 3" all the way out the back. With the bigger cam, it doesn't start to sound like it is happy until 4000 or so. With my converter, it is moving right off idle. It doesn't stall above 5000 unless it has traction or it is on the transbrake.

[Awesome Bill]

If its working, leave it alone. A very large cooler is a great help with the heat. Either way, it still sounds fun but I would not recommend that with real street cars. Pro Street cars o.k. But its working for you and sounds fun.

[lun40119]

The only time it ever gets up over 200° is if I am running it hard on the street with some WOT pulls with the blanket on. But if I get up on the highway and cruise it will cool down. 180° or so.

I dont have any problem with mine either

You can get a converter to lock up under the stall, until you get back on the throttle

Yes, i run a large cooler with a fan. I also run race type f fluid. No problems running hot

I think alot of problems are people that paint transmission cases, paint holds heat in and they paint them, my case is natural aluminum (i myself have seen a temp difference in this area)

I also think transmissions on the street run cooler with a transbrake valve body like i have and Jake due to no govener, no front band/circuit. Quicker release of clutchs in direct and more fluid / line pressure

Jake and i basically have the same t-brake. I like Hughes, JW and ATI. I dont care for the internal solenoid on the ATI but you never know i may want it one day

[lun40119]

Was out this past weekend playing on the twisty's and had the blanket on it. After 6 or 8 wide open blasts through 2nd and 3rd, trans was 220°+ in the outgoing line. Just an FYI. Still managable, cooled right down under normal driving. Took the brakes a little longer :cool:;):cool:

[Awesome Bill]

a 5500 stall is where at wot the converter will catch the engine, keeping it around that rpm with good traction will produce where most engines like his really start to make power. They are kinda down on power under 5000rpm because of heads, cam, intake, carb etc. But, you can drive a 5500 real stall anywhere you want to go becaue with out a trans brake or you pulling a tank with you, the car will take right off just like a normal one will. There is slippage and this causes heat but he seems to have it working for him. hthelps

[lun40119]

You are right with that post, the only time it really see's 5000+ is on the transbrake, or when it has traction, other than that it has the tires boiling at any mph, by 4000 rpm.

[Awesome Bill]

You still have to remember when your under that, the converter never locks up, it can't, and that is where heat becomes a factor. But, you seem to have that under good control and have had little problems. I never said it could not work, just most guys do not take the added steps to keep the heat down with heavier or cars down on gear.

[lun40119]

Cool, cool, I think when we leave for the Power Tour, I am going to take the blanket off it. Seems to be the biggest contributor to heat. Or heat retention. Eitherway, good to have you back posting.

[Awesome Bill]

that would most likely allow some added heat release with out the blanket. The paint deal you talk about is dead on. Its pretty but holds in the heat.
