I am going to be using a forged eagle crank now, the callies counterweights are for 6 inch rods

This sounds like a great project.. Unfortunetly, I had to pay someone to build mine as I don't have the patients and more... LOL Keep posts pics on this one as I am very interested.

I'm using a eagle forged crank in my 400 stroker for 6" rods. Shes held 8k rpm several times sofar..

If i knew i had to buy a crank beforehand i would have went 421 or 434

Can you not use 6" rods? I guess you already bought pistons but could you return them?

355sleeper

iTrader: (4)

Thats the problem, i have both 6 and 5.7 h beams but my pistons were special order same with the rings since they use the bastard 1.5/1.5/3mm.

So i doubt i could, ill just live with it

355sleeper

iTrader: (4)

well the machine shop had already hung the pistons on the rods so it will stay a 406 sadly. i ordered the crank so i should be getting that monday or tuesday then next on the list is the cam. i decided to go weth meth injection instead of an intercooler also.

it will be a pre carb injection setup, what size nozzles should i be using or is there a kit for it? cooling mist and devils own i think id have to piece together

iTrader: (4)

picked up one of these also

http://www.classicdash.com/shopping/...-90-50924.html

it will probably be another 10k to finish the car excluding paint. i found a place that sold that crank for 449 so jegs priced matched it. after tax and shipping it was 495 for a crank jegs sells for 573!!!!

since an a1000 will be too small, I will be swapping fuel cells for this fuel cell set up. i wont know how to act having a working gas gauge and speedometer!!!

I got the crank and it was at the machine shop first thing monday morning. I got the instrument panel last night. It looks great

be happy ur staying with a 406, as osmone in the middle of building a 427 i can tell u it costs alot and building a 434 on a short deck block will have longevity issues

Orr89RocZ

iTrader: (20)

Briefly thought about making mine a 415-427 since i had to tear motor apart. Cranks and rods seem to cost same but piston choice gets more limited. But i realize my block will be the limited factor not the rotator

project89

iTrader: (1)

i have almost 3,800 in a crank ,rods and pistons then again i dont think u guys would spend as much as ur not going for obscence power levels lol

by the time the shortblock is assembled ill prolly have around 7-8k in it with machine work and assembly

lmao my engine will be worth 5x what the car is lol

I called turbonetics and they said i should use the. 68 housings with the 66s...

What are your thoughts on this, he didnt say why or explain himself just wanted to get me off the phone. My max rpm will be 6500 shifting around 6200

Orr89RocZ

iTrader: (20)

I'd say they would work great to 6000 and start to become a restriction. Thats the size I ran with the T60's I had and a small head/cam setup and it was very torquey, spooled super quick and ran verry hard. I think you will like it and its the perfect size for 600-700whp IMO

355sleeper

iTrader: (4)

In the event that i do turn the 2 step up to say 5k would the. 81s be better or the. 68 72mms

Orr89RocZ

iTrader: (20)

Depends on the power goal. More power more exhaust flow required. More rpm also more exhaust flow. So need larger turbine side. Should measure exhaust pressures pre turbine. I didnt measure mine but seemed to pick up power with each pound of boost til about 16-17 psi but by then i really think my backpressure was up due to peak rpm being lower than planned. So i think under 6k rpm and 650-700 whp, .68's on a 64mm turbine should work pretty good. .81's for more power or abit more rpm. .96's for 1000 hp and 7k rpms

You should spool those 66's with .68's by 3500 easily if heads and cam are well matched and good flow. I know my 401 did

355sleeper

iTrader: (4)

I dont want to rev the **** out of it until i have the funds for a little m block then ill step up to some better components and more cubes. Would it be possible to have full boost out of the 72s with the. 68s by 4k or so rpms? If so ill go that route so i dont need to buy turbos in the future

fast82z

iTrader: (1)

I never looked, but it can't be that expensive to buy a set of exhaust housings in the future if you want something larger. I logged exhaust backpressure on my 406 with twin .68 a/r's and 67mm compressors and it was just above 1:1, meaning the exhaust had just a touch more pressure in it than the intake did. That was as high as 20psi, which you shouldn't get to for quite some time.

Orr89RocZ

iTrader: (20)

My exhaust housings were 130$ a piece. I have .68's and .96's lol nice to have options. I want to test them both but problem is the housings are about .2" different in width. This throws my downpipe alignment off with my wastegate so not sure i can easily swap.

Either way thats good news to see .68 on a 406 having near 1 to 1 ratio. What size turbine wheel? I would have expected abit higher as .68's are tiny housings. Guess it depends on entire combination too, with the heads/cam and header/hotside design.

I think .68 on 72mm will spool by 4000-4500 because my .96 70's start to get in boost by 3800 and appear to reach full by 4500-4800 depending on how much boost i am running. They are tad big, .81's would work best for me but arent available.

Last combination i seen tested with t70's on a 406 was on a mid high 8 sec car. Going from .68's to .96's greatly improved his top end trap speed at the track and delayed spool only few hundred rpms. My combination is very similar to his so hope to see 155-160 mph on 20+ psi as well

The turbine wheels were just the standard p trim 64.5mm exducer.

After talking to precision turbo i am going with them. Turbonetics was terrible to talk to. I will be using the 6176s, theyre less than 100 more per turbo. They have billet wheels also. And i will be using. 68 housings. Should be getting them very soon.

They rate them at 670hp per turbo

Orr89RocZ

iTrader: (20)

Sounds good. You will love it. Had a few friends run precision stuff over the years, all with success

355sleeper

iTrader: (4)

ordered turbos saturday, im not sure what kind of turnaround time there will be. they will be dropshipped from precision.

they are the 6176e's in the .68 housings.

precision did say these wont run out of steam until around 6500.

Ordered a jones solid roller .600/.600 lift, @ .50 245/245 duration. 112 lobe separation.

355sleeper

iTrader: (4)

Picked up a set of 10secgoal headers, said hes 4 to 6 weeks out. Much easier than scrounging for a passenger side header

355sleeper

iTrader: (4)

Turbos came today!

Orr89RocZ

iTrader: (20)

Sounds good!

Got my stuff from the machine shop today, he was still balancing the rotating assembly so im short just the crank since it was already on the balancer. I got the rings filed. Now im just waiting on that and ill slap it together. Also decided to pick up some head studs. Cam should be here this week too! Cant wait to drive this thing

355sleeper

iTrader: (4)

What do you guys think about 22psi without meth inj? Ill add that later on. Final static compression is 9.28:1. The iron heads are the only concern but I think it would be fine with conservative timing. Thoughts and personal experiences are greatly appreciated. Again this is non intercooled

355sleeper

iTrader: (4)

Got the long block assembled just waitin on cam and headers to get it all buttoned up. I thought i had the snug mount powermaster kit in 100amp, turns out it was only 50amps. Gotta buy that and electric water pump to get it ready to drop in.

Orr89RocZ

iTrader: (20)

Thats alot of boost. Pump gas? Eh i am not sure that will fly. If aluminum headed maybe but iron holds heat in and at those pressures thats alot of heat. Would need intercooler for sure. Race gas should handle it but thats alot of power to be playing with. I hit 18.5 psi on my 9 to 1 motor with straight pump 93 and no meth, aluminum head. Probably could have taken more but i ran out of spring

355sleeper

iTrader: (4)

E85, ill start out at 15psi and go from there. Still waiting on cam and headers so I can finish the motor though. Picking up ignition system tomorrow. Mallory hyfire, promaster dizzy/coil. And some odds and ends. Still has a long way to go. Waiting till its all together before it gets paint

Orr89RocZ

iTrader: (20)

E85 may do it. Intercooler definately would be a plus but E85 does wonders with boost and compression

Ive emailed 3 places to get a blow through carb, c&s, horsepower innovations, and pro systems. Only pro systems has gotten back with me. I was qouted 1290 for a dual needle and seat e85 carb which I dont think is too incredibly overpriced. I think that will be my next purchase

355sleeper

iTrader: (4)

I ordered a dual needle and seat 950hp based carb today. I ordered it from eric @ horsepower innovations. Great guy to talk to and said the motor will make right around 1000 at the flywheel at 15psi. Downside was it was almost $1400 shipped.

After talking with my machinist about my ring gaps I called total seal and was informed I needed a better set of rings and much wider gaps than what I have. Ordered csh 2012-35 rings. These have a steel top ring as opposed to the moly. Ring gaps will be .027 top and middle rings

Orr89RocZ

iTrader: (20)

Good deal. Get it done good carb is worth its weight in gold

Im glad I didnt get my cam yet or the motor would have been in the car.
I think your the only one watching the thread lol. Thanks for the support!

18 lbs of boost on a stock 400 blocK? sounds scary to me.

355sleeper

iTrader: (4)

Splayed and head studs, its all I can do to keep it together. If it goes, looks like im going to a dart little m. Ordered a extreme velocity pro hat and a little over a grand of little stuff.

Is a breather tank off one valve cover and the other breather open ok? Or do I need a tank for both valve covers?

ibmtech

iTrader: (1)

Why don't you go with the dart iron eagle instead of the little m? I went through ultrastreet.net when I ordered mine.. Just curious

Orr89RocZ

iTrader: (20)

Probably easiest to run both covers to a catch can. Dont want stuff blowing out the open breather filter on other side. I find those little breathers can soak up oil mist and start dripping

355sleeper

iTrader: (4)

$$$ thats why, i didnt want to spend 2k on a block yet, ill wait until this motor .goes before stepping up.

And ill go that route, just need to pick up another set of headgaskets and another locking breather and take the single inlet breather tank back for a dual inlet and were in business. Still waiting on cam after 5 weeks!!!

355sleeper

iTrader: (4)

A little update, I got cam! Longblock is back together with much better ring gaps.Cam finally showed up. Actual specs are .582/.583, 244/244@.50, 112 sep,110icl. Got my carb, hat, and 1 inch spacer for it.

I am still waiting on my oil temp gauge/bung to be able to put the pan on.

Also went a different route on headers, I got my money back from 10secgoal as he was taking forever. I talked to wrenchrat and ended up getting a set of headers/downpipes and the intake merge pipe from them. Steve already had a set made and ill get them next week!

Ill be sure to post up pics of carb/motor/headers when its all together!

Pics of carb, thanks eric @ hp innovations

Extreme velocity pro o ring hat, and c&s 1inch o ring spacer.

Got the valves lashed yesterday, need to put the pan and intake on and thats it for the engine. Headers/downpipes will be here monday and ill have some pics of those also.

Most definitely will have to cut the hood for this massive hat!

Build will go a little slower, picked up a 2012 camaro ss with 4k miles on it today!

I did get my wrenchrat headers today and they are sweet! Will get some pics after the phone charges.
