circle track 525 hp question

[belowfire]

does chevy dyno this engines underload to get rwhp or is it flywheel hp?

[Squirrel]

All their numbers for crates are via flywheel, what would your plans for this thing be?

[belowfire]

my 1986 Trans am

[BonzoHansen]

specs? circle track motors usually run at specific rpm ranges and may not be great on the street.

You can pick up a gen 1 block that will make that power with ease for a LOT less money, and it'll drop in a lot easier and you can still have a carbed car

[belowfire]

only reason i was thinkin it was i no of one cheap and you mean genIII/V blocks?

[BonzoHansen]

btw there are no specs.

dude that is an $8900 engine and you still need all the accompanying parts.

well i want about 450rwhp on a carb ls motor so u guys got any better ideas?

[BonzoHansen]

is money an object?

[belowfire]

no not really

[LTb1ow]

Buy a cheap 5.3, throw a carb intake on, run a carb, get ****** mpg and enjoy having a ****** carb on a great efi motor. #success..?

[BonzoHansen]

you're 18 and have no budget concerns? nice.

why bother with LS and a carb? if you want to run carb why not do heads & cam on that 350/290hp you sig listed?

ls?

your sig also says t56 but i remember you having issues with a th350. is your info up to date?

[belowfire]

do i look like i care about gas mileage? n nothing sounds better then a nice cam n a carb everyone has there choices n i like carb alot of ppl like efi thats there choice

[belowfire]

i just kinda blew up that motor the other day... and i have a budget its all not gonna get done right away

[BonzoHansen]

$$ wise you'll probably be far ahead with a pull out 6.0 and go from there. iron block engines are not that expensive.

[belowfire]

So iron block 6.0 out of a truck hmm i got a set of 6.0 heads laying around they worth machine work or should i juat get after market?

[Paul Huryk]

6.0 or 6.2 LS motors are the way to go - get one out of a wrecked truck or car.

Keep in mind that you can get 530 to 570 streetable HP out of those motors with just a cam, heads (sometimes stock ported), and tuning.

You will need a totally new exhaust, upgraded fuel system, electronics, and other items to make that work right.

Carb is counterproductive on a car with limitless EFI tuning capability...

[WSex]

lq4 iron block 400$
stroker kit 3500$
moroso windage tray with nozzles 500ish
custom turbo kit 2000$
intercooler 700$
valve train
and a carb setup with good cam and you got yourself an accident awaiting to happen.

if i had no limit thats the way id go but fi

^thats my wishlist too if anything spares lol.

[belowfire]

Ok so iron block 6.0 i can get one for 200$ its a long block fuel systems easy to get now it comes down to the harness computer and intake n all that fuel ignition **** i dont raeally like lol. Marry it to a t-56 transmission. My exhaust i no ill need new headers but i have a brand new magnaflow cat back on her. So to start ill get the 6.0 heads worked cam i have no idea what to get. Ill most like put this motor in carb first becauae i have the carb conversion kit( got whole thing at swap meet for 50 buchs). Lastly if im going to be running an iron block fuel injected this motors gonna get super charged,

[shadowfire]

umm if money is not object just go but a new zr1

[WSex]

supercharger!?

supercharged is for babies

turbo for more cockpit heat in the winter

[belowfire]

Cockpit heat?

[coolmanvette75]

There is so much fail in this thread my head feels like its gonna explode.

OP if that car in ur avatar is the car for this motor in question just buy an ls 4th gen and build it

[belowfire]

I letting the thread go anyway it wants mite as well explore every option n im building this car not buying a new one. This isnt my only vehicle its just the one i actually put money into.

[shadowfire]

you dont want to buy a new car?? how much money are you willing to spend?

[S.J.SLEEPER]

5.3 or 6.0 take out
arp rod bolts
arp head studs
ls9 gaskets
twin 340's in-tank
88mm turbo

and ENJOY!!!!

or staying with sbc:
4bolt 350
brodix M2 heads & cam (track heads ported by m2 racing
750 w/venturi or 850 carb
= 500 @ fly
than add a 150hp shot of the good stuff on it. (wet kit preferbly)

[belowfire]

Im in love with 3rd gen firebirds i want to build it to be a fun good looking car i have an 07 f150 as my daily driver. New cars just dont interest me(but there motors do)

he knows what he is talking about SLEEPER is the man

[deadtrend1]

Is there any plan/goal here or are we just throwing out money is no object dream build?

[belowfire]

who knows you can throw out ure dream n something under 25k

[sweetbmxrider]

Is there any plan/goal here or are we just throwing out money is no object dream build?

Seriously. Wtf do you really want? Don't just say 500hp or something stupid. What do you really want from the car? What do you want it to do? How much are you really willing to spend? Honestly a mild heads/cam gen III is lots of fun and capable of high 10s or quicker in the 1/4 if the car is geared towards that. If you want to road race/autox, well you'd want something with power in the rpm range you'll be in. Is your trans even built? 400hp will ruin it sooner or later and you'll be $2-3k having it built. What rear is in the car? We all know how that goes. What has been done to the suspension? Why are you so afraid of efi? Sure its a bit of money to retrofit a gen III efi/computer system into your car but it is definitely worth it.

[belowfire]

street/strip car, t-56 is built, rear i need to order (havent desided gear ratio yet). rear suspension hotchkis everything but springs, umi subframe connectors(not installed yet) 4th gen style torque arm for t-56. ordered full front end coil over kmember kit for ls swap. breaks going 4 wheel disc(havent ordered yet) all that ive spent so fair equals up to alittle over 7k rears gonna probably be another 3k brakes 5k i have about 10k to finsh rest of the car until i have to start saving up again im looking for about 450 n up at the wheels. sorry for confusing anyone and pissing them off just was asking a question and then looking for opinions.

[sweetbmxrider]

450 is attainable and if parts are chosen properly, very streetable. Lots of other guys on here are better than me at gen III setups so I'll let them tell you what works best. With 10k, you can probably just about do a fuel injected swap with a premade speartech harness, stainless longtube headers specific for a gen III in a 3rd gen, and gauges to wrap it all up.

[deadtrend1]

Seriously tried to read that but got lost halfway through ...

So... You want a street strip car, want 450 hp roughly, and you have 7 grand into the car already?

What Brakes are 5,000 dollars?

[Mike]

Fail brakes

[Mike]

That is honestly most likely too much rear brake. There are so many better options for about four thousand cheaper anyway

[belowfire]

n yes deadtrend

[deadtrend1]

Holy crap, aside from hawks horrible price inflation, theres much cheaper and still very practical alternatives.

[belowfire]

most likely but i like the best of the best

[deadtrend1]

Mike beat me to it

[belowfire]

i can return the bcks seeing there unopened n unused

[deadtrend1]

Return them? So you already bought them?

[Mike]

Then you wouldn't be building a carbed third gen

[belowfire]

yea just havent paid for em yet my dad bought them for his 3rd gen used front onces sold his car to put downpayment on his maxium so he told me there mine n wants the money for them

[belowfire]

i love carburetors but realisicly im stupid for wanting a carb ls motor

[belowfire]

realisicly i make alot of stupid choices lol

[Mike]

You know this and still make them?

[belowfire]

yea love the car too much to give up on her

[zraffz]

No budget?! ... if I didn't have a budget I certainly would not be running a carb on anything I own.
Why take modern technology and go backwards?

this os when people start to hate me

[//<86TA>\\]

that Baer rear kit is way to much rear brake, these cars dont need a ton of rear brake since when braking the torque arm transfers most of the weight tot he front. A huge brake kit like that one the rear will have to be dialed waaaaaaaaaaay back with a prop valve to the point where it wont even work to keep the rear from locking up and making you spin out and wreck.

also, they are fixed mount calipers on the rear, and that will not work with a c-clip axle, you will have issues with pad nockback

i have the 14" version of the front kit, its totally badass, but you will need to make sure your wheels will clear the calipers, they are huge. I paid 1k for mine.....

You would be surprised what the factory c5 or 4th gen fbody front brakes will do with a good set of pads, and cost thousands less, and will fit in almost any wheels out there.

[belowfire]

wsex if thats ure thats ****in beautiful! n ok everyone **** the carb idea

[WSex]

wsex if thats ure thats ****in beautiful! n ok everyone **** the carb idea

i wish lol

but yes fuel injected is the way to go
spank racers by night get 25+mpg by day

[WSex]

talking of brakes
my buddy picked up cayenne brakes for 1000
those things are bigger than my whole car

[WildBillyT]

My brain hurts trying to follow this.

What condition is the base car in? Body, paint, suspension, etc?

[NJ Torque]

WoOoOoOw. . .

[belowfire]

lol body was just painted only problem is the fram under the doors are dented because of in proper jack position.everything rear suspension hotchkis lca panhard bar sway bar bmr lca relocation brackets koni yellow shocks. have umi subframe connectors(not installed yet) and the front kmember coil over kit was ordered today also have t-56 4th gen style torgue arm(not installed yet).

[belowfire]

going back n reading all this actually made my head hurt too sorry for the retardedness guys

Would be lame on the street, get a nice lil 76gts and have lots of boost instantly. And in tank fuel pumps are so yesterday, get a cable driven magnaflow for maximal pumpage. That and some 20% over sticks with a modded CP3 pump, you should see well over 800ft-lbs by 3k rpm.

[Jersey Mike]

Easier:
Ls3 416,TEA TFS 245, EPS cam - 549rwhp 479 rwtrq (http://ls1tech.com/forums/dynamometer-results-comparisons/1562312-ls3-416-tea-tfs-245-eps-cam.html)

[LTb1ow]

Cause a vacuum pump at 10'' is great for street use.

[bigz28man]

Reach out for a company called morgantini race engines, a friend of mine who runs on the nascar modified tour uses their motor.they will build you a motor to you needs but know this these motors are running with rear ends that have 5:7 gears of high. Another thing you can do is head over to wall speedway and talk to one the modified owners in the pits, one of them may have a modified spec motor they are looking to get off thier hands. Those guys are running with a 500hp motor and some are running with more.
