okay Nathan I have a feel from where you are coming from.

I wouldn't suggest getting a 400, they are sometimes a bitch to come by and need "special parts". What I mean by that is that if you need new heads then you can only use 400 heads (which are pretty shitty). Most people use 350 heads and have them machined with that extra water port found on the 400 sbc. I would say stoke a 350 motor. A 383 can put down some serious power.

Your biggest challange will be fuel managment, have you decided what you wanted to do with that yet?

Here is a good website to show you what to do to build the ---- up:

If this guy has some money to throw around then go for standalone fuel managment but carb setup will work.

Let me know your progress, I'm going to start one of these TT v8 setups soon as well (a few guys around here want to).

I was just planning on a FMU unit or something like that....

dont feel like spending a hsit load on a stand alone and im pretty sure i couldn't chip it with turboedit or anything

yeah the 400 was made in the "smog era" or someshit right? so it's ports are mad small...but yeah

there is one guy that has a 400 otherwise he'd prolly go wtih a 350...

it all dependson what we find

what options do i really have as far as mangment?

would the AFC hack work on this....if it would it'd be tight as ----



one more thing, so like a pair for 14b turbos should be pretty good size? they run like 2.2L so yeah...we'd like the turbos to spools low becuase the redline is like 5500 on this motor

Yes there is port differences between all differnt casting number heads but all sbc heads from 267,283,302,307,350,400
are interchangable.The 400 has 2 steam holes in them so all you do is take a 400 head gasket center punch the 2 holes between the cyl an drillem out.I checked out the page on the twin turbo setup an thats alot of work on welding.I got a set of block huggers an turn em upside down an built exhaust from there into a single t3 spools quickly 2200 an pulls all the way to 5k or so to busy driving to just look at tach.

I've never fucked with any 400s so I don't know the specifics but I did know about the ports in the head.

I'm with Ted on this one, T3 would be more ideal. Try and find a couple off those older chrysler K cars. Those cars are 2.2 and 2.5 litres and should be able to flow on a 5.0.

---- your stock fuel delivery system man, go standalone. With man standalone setups they are live feed to the laptop and can do more then uberdata (no chip burning needed either).

I'm drooling over some ultra megasquirt, look into that ----, build yourself a $1000 setup for a couple hundred bucks.. I can't wait till it gets released!

why go fuel injection theres guys doing 25psi through a carb. What i have learned on my setup i pretty much got the carb mods down to a tee. My fuel on a wide band is comparable to a fi setup.Check out this 7 sec carburated blowthrough turbo video.

just thought i would add this to this thread.

do those ports look small?

Cadracer

well no, Those heads look exactly like the ones i had on my camaro.They where world product heads.
Hm that even looks like a rpm preformer manifold.I like the holley strip dominator myself straighter ports an more air under the runners for better heat transfer....Also i see those heads are the dual valve cover set up center bolt an outer bolt....

Nice engine you got there.

J-SMITH69

heh you are good i must admit!

Cadracer

Im the small block guru of hmt. I got just about any sbc engine you want or need in my garage.My plan was to turbo a 400 sbc but the block need to be decked due to some minor rusting around a head bolt hole an this made pits under the headgasket fire ring.An with the pistons i had it would have given me to much compression to turbo.So i goona just throw my 350 with some forged slugs in for now till i get the 500 caddy engine ready for the twin turbo swap.

J-SMITH69

its a holly street dominator manifold :P
