I have a few pics of the 355 whilst it was in the build; as you can see i used the H beam Scat kit

Has had mild head work, ls1 valve guides, match porting polishing etc Also in photo below you can see i have used a stud girdle instead of four bolt mains. Also had to have the ASR sump made custom to fit around girdle!

Can see that i have had mild port and polishing as nothing to crazy is needed as dont want to slow the air flow down too much, or will go backwards in power!!

Got a bit bored so me and my panel beater decided to make the rocker covers look trick and give the sump the same treatment!

And once it was all together it looks a little something like this, should go well with the twin throttles and other billet goodies

Because of the increased power i thought a set of ve 330mm brakes was in order for the front, as the little vs brakes just did not cut the mustard! Also when towing etc i was getting huge brake fade.
They also fill up the rims a lot nicer and after some two pack Ferrari red they def look the goods, not to mention it stops on a ten cent piece! Have the standard rear brakes with the DBA Gold series cross drilled slotted rotters for show!

I was orig going to run the trickshift twin throttle manifold. Its a cut and shut job of the stock bananas. I didnt really like the look of a carby style manifold with a 1000cfm throttle on it.
I was lucky enough to score a walkinshaw twin throttle body set up that had the plenum modified as it had twin gas research throttles on it. Came with no throttles or fuel rails so i am in the process of setting up throttles for it.
When i first got it it looked like this

looked a bit tired so had it beed blasted and thought the plenum would look nice polished. Guess it looks ok

Still needs the lower manifold sprayed. Will be the same colour as the rocker covers. Got my self a real walkinshaw throttle body that has been shaved as they are a XF Ford throttle so lots of lumps and bumps on them from deleted vacume lines etc!
Not running the 2nd throttle as an 80mm i would rather run the standard XF throttle. As a 2nd throttle is 80mm and is not needed, not to mention the inlet in the plenum is only 70mm as was modified!

From this messy looking throttle to this!

As you can see it has been dye grinded and ground, now just have to weld up holes without warping throttle body Still need to fab up linkages to operate 2nd throttle

She doesn't look like a Group A Manifold, The bottom runners are different an the front has elongated holes to the right of the thermostat housing an the front of the housing is a different shape.

Curious what manifold it is tho...

Apart from that, Nice ute

Yea it ain't a grp a. It's a vl Walkinshaw manifold. Hence runners look different lengths.

the one at top of pic is my manifold (vl walky) and the top one in GRP A manifold. Grp A plenum sits flat but vl sits on an angle!!!
If u take plenum off they come thru at different lengths as u can see in photo! Also thermostat housing is in different position on grp a as it's offset to the left.

TROLOLOLOLOLOLl!!!!!!!!!!

 

[dobesz]

Maybe but considering i got the manifold for under two grand i thinki did ok Not to mention it was modified to work better with a stroker as it was designed to work with a 5l. So in theory plenum should be larger for stroker!!!
Could be worse....could have standard bananas
