Re: 434 stroker vortech v7
 

jesus. Whats a 434? Bored and stroked 400?

Re: 434 stroker vortech v7
 

That's sweet. Did you do the work yourself? What's the estimated hp?

Re: 434 stroker vortech v7
 

it's a dart 400 block bored .030 over with a 4in stroker crank

Re: 434 stroker vortech v7
 

I pretty much did everythings myself except for machine work and the intercooler piping. If I don't see over 850 to the wheel I'm gonna be pissed

thats awesome post vids too and dyno numbers

Re: 434 stroker vortech v7
 

where did you get those thin wheel adapters/spacers?

Re: 434 stroker vortech v7
 

700r4 trans? I dont think it will be happy for long. Should have no problem making those numbers tho on likely 18-20 psi i think depending what heads cam are on it

Re: 434 stroker vortech v7
 

Re: 434 stroker vortech v7
 

Yeah upgraded the trans from the Mad dog.....it's a beast 700r4...made by animal transmissionshops should hold about 1100hp

Re: 434 stroker vortech v7
 

Heads are afr 235 cnc ported cam it a comp cam custom grind I will post the specs

Ebay.....I've had the so long I don't remember the eBay Store name

Re: 434 stroker vortech v7
 

Is that the stock vortech manual tensioner you are using? If so, then you will have issues trying to get more than 7 lbs out of it. The stock vortech manual tensioner blows chunks.

What blower are you using, ysi? What pulley combo?

I made my own bracket with automatic tensioner and got 12.5lbs, but killed the trans and now the motor is being rebuilt.

Re: 434 stroker vortech v7
 

Yes it's a v7ysi as of now I'm using the 10rib with the stock tensioner....I have a few different pulley set ups.... on the car now is a 6in crank and 2.95 on the blower.......I also have the 8in crank pulley still in bubble wrap ......I also have the dual plate system to use the cog pulley but no cogs yet......I'm gonna see what happens with the 10rib system.....b4 I buy cog pulley

Re: 434 stroker vortech v7
 

Do you mean the spacers? Thinnest I can find are 20mm

Re: 434 stroker vortech v7
 

I'm got a vortec V1 T trim.. with a cog drive..it can put out more then I would ever use..
as for the 700R4..it took $2300 in just Sonnax/TCI hard parts... and cryo treating other parts.. the converter was $700 on top of that..
don't know of any body whos putting all the newest hard parts in the 700R4..but thats also with a trans brake..

Re: 434 stroker vortech v7
 

I dont know anyone using a 700r in any high hp setup with success lol. Th400 or 4l80e only. But on the net i have seen posts of buick gn guys using 200r4's well and some vette guys running 4l60e variants into the high 8 low 9 sec range but the price for that trans you can have a 2000 hp capable th400 or 1500 hp ish 80e

Re: 434 stroker vortech v7
 

have always had them hold up to 500hp to the rear wheels.in the 90s..now will see if it can take a bit more... the big thing now it making it close ratio. with over drive..in the size it is..anybody can take a th400 and add a overdrive..its alot bigger and yes can take 1000hp

but.. that's a th400.. lets see some one make a close ratio 700r4 that ya can beat on..and use the parts made to day..its not cheap..
so your not going to buy one for $1800...lol
and now ya don't have that RPM drop from 1st to 2nd..and 2nd to 3rd...its about time!

today you can buy a 800cid eng making 1200hp on pump gas NA.. no boost or Nitrous...its all about having fun..and having $70.000

Re: 434 stroker vortech v7
 

What do you think of the cam specs

Re: 434 stroker vortech v7
 

go with a 1.6 ratio on the rockers. as the duration is a bit low on the intake..just me..
remember with the larg cid small blocks..the cid eats up the cam size.. intake a exst duration in the 248/250 with the cid your running will not act like in a 350 383 cid...= will feel like a smaller cam...in a 434...and the sound of the larger small blocks..well youll like it..
the things we do to make things fit
Attachment 314704

Re: 434 stroker vortech v7
 

Its alot smaller than what i'd run on those heads and cubes. I'd go 10-12 deg bigger and a 1.6 rocker

Re: 434 stroker vortech v7
 

Update I went to the dyno back in September the car put out 926 pound feet of torque only 575 horse at 4600 RPM we did not have big enough injectors to make a full so we stopped after that time I considered upgrading the connecting rods to hold more power during a disassembly noticed that it had to lifted ringlands they were damaged before the dyno

Re: 434 stroker vortech v7
 

I think that we could have got more horsepower out of it with more tuning on the timing but we felt that it was so dangerous that we should stop until we had enough fuel

Re: 434 stroker vortech v7
 

So my plan is to come back bigger and better for the upgrades header size during these pulls was an 1 5/8th

New header 1 7/8th stepped to 2"
New camshaft
1206 port job on intake

Re: 434 stroker vortech v7
 

What injectors are in it?

you’ll want something closer to 80-100 lbs hr for gas nearer 900-1000 whp

Re: 434 stroker vortech v7
 

What crank and blower pulley sizes?

Re: 434 stroker vortech v7
 

I'm running a 8-inch on the bottom 2.75 on the top this pull was on 13 lb I'm doing something called at torque booster setup which is popular with the Ford Community I have a wastegate installed on one of the charge pipes and I bleed off boost similar to a turbo setup I'm using a boost controler

Re: 434 stroker vortech v7
 

I had a set of holley 66's at this time I have a set of Holley 83 is now

Re: 434 stroker vortech v7
 

what headers do you plan on using? off the shelf ones or a custom fabricated header?

Re: 434 stroker vortech v7
 

Just ordered ed quay headers

Re: 434 stroker vortech v7
 

nice Ed Quay. . I think that is going to be my best option too. I live only 2 hours from his shop (and my wifes parents house is only 20 mins from his shop) so theres a chance I might just bring the car there and either have them build them in the shop, or just take measurements and ship them to me. let me know how you like his headers, photos, etc from the info I have read on TGO, his headers seem to be the best big headers that don't sacrifice ground clearance on lowered cars

Re: 434 stroker vortech v7
 

Following :)

First cam looks similar to the one I have right now.

I also ran out of injectors but that issue should be solved now I hope.

/N.

new eq quay headers 1 7/8 stepped to 2" 😁😁

Re: 434 stroker vortech v7
 

Finish welded. Super happy with the workmanship

Re: 434 stroker vortech v7
 

looks awesome. will you be ceramic-coating them? whats a ballpark price? $800 or so?

Re: 434 stroker vortech v7
 

:thumbsup:

Re: 434 stroker vortech v7
 

I paid 860 I'm going to cerakote them should work well from all the reviews

Re: 434 stroker vortech v7
 

good! great! exactly what I was hoping to hear. nice work man

Re: 434 stroker vortech v7
 

Those are pretty!

Re: 434 stroker vortech v7
 

I hope your transmission last because you have spent alot of money on it.

Re: 434 stroker vortech v7
 

Do you think the stealth ram is choking the system? A lot of guys are running large single plane set up.
Your set up looks great. I'd love to run something like this someday too.
Who did the exhaust?

Re: 434 stroker vortech v7
 

I think the stealth ram like the miniram is ok to about 63-6500 rpm on a NA big cube. Supercharged I wouldn't know. My builder has a custom ported miniram by the owner of AFR. Was tested at 415cfm. But it's on a 450 sbc.

Re: 434 stroker vortech v7
 

A buddy of mine pretty much made the adjustments to the Speed Engineering 4th gen kit

Re: 434 stroker vortech v7
 

I was thinking that I was going to have issues with the stealth Ram but I know a few people making the thousand horsepower Turbo with the stealth Ram he was running slightly smaller cubic inch and only a 1205 Port job

Re: 434 stroker vortech v7
 

I believe my biggest restriction was my headers it was only a 1 and 5/8 tube
