No as that would alter how the coolant flows through the engine.  The majority of the coolant flows through the block (around the bores) up through the back of the block into the head and back through the head to the thermostat with some coolant coming up through the block around local hot spots.  If you were to enlarge some of those steam holes than you risk not getting enough coolant towards the back of the engine creating a hot spot there.  The earlier s1 V6 VN had bigger steam holes because the coolant flowed in only one direction because the thermostat was at the back of the engine so they needed to get more coolant up into the head at the front.

383 is a common Chev size.

Originally they used a 3.75″ crank from the larger 400cu engines ground to suit the 350 block, later the after market took over with cranks specifically for this upgrade.

COME do a 396 stroker kit for the Holden engine.

The biggest hassle going bigger than 355 (3.48″ stroke) is that you hit water when grind clearance for the longer throw of the stroker cranks.

The heads have both holes as they are interchangeable (from left to right) but the manifold only has the cross-over on the front where the thermostat is.  This is normal.

Looks right, the s2 have the smaller steam holes.

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Yep, sounds like a series 2 engine.  intake manifold should like the S2 below.

The series 2 motors also have an extra hole in the head on the intake flange for the PCV system (you can see the matching hole on the intake manifold that the series 1 engines don’t have), is this possibly the hole you are referring to?

V6 motors overheating in a hilux conversion is a fairly common issue with the tight fit in the bay.

There are subtle differences between the series 1 and 2 head gaskets due to the coolant flow path through the engine.

I’d say it would be safe to remove it.  Could always cap the breather line just to be safe

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Not sure TBH, is it connected to anything?  Is there any actual fuel flowing through the flow meter?

What is the other end of the vapour return line connected to?  If it goes back to the fuel tank then it shouldn’t be an issue.

Until he puts his foot down…….

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

I wonder if that is the fuel flow meter for the dash so it can work out fuel usage.  Something that was fitted to SLE models.

It couldn’t hurt to throw a HEI type coil on it.  A lot of guys use the MSD Blaster type coils.

Most likely it is manifold vacuum.  Manifold or ported vacuum as far as I’m aware has to do with the relationship of the vacuum port to the throttle blade so that it only sees vacuum when the throttle blade opens past a certain point.  If the vacuum port is below the throttle blades than it will see manifold vacuum.

Yes, vacuum hose from carby base/plenum to vacuum canister.  With a vacuum source connected you will get more timing advance when cruising which should improve economy.  This is for a stockish engine of course, if it’s a built engine with a decent cam/compression then it may be a different story.

Hey,

1.Depends on how old it is.

2. It’s part of the PCV system.  not 100% sure if it’s ported or manifold vacuum.

3. doesn’t really mater much where it is located as long as the fuel is filtered.  put it where ever suits you best or looks better to you.  Personally I’d somewhere away from heat sources.

4. This is the fresh air source for the PCV system, yes if you want a legal car as the PCV system is part of the anti-pollution stuff.  Many do away with this stuff but for a run of the mill road engine may as well leave it in place.  Best bet would be to fit a catch can in the line referred to in Q2 as this is where most of the oil will enter the intake system.

5. Can’t see it properly in the pic but I think it might the the FPR (fuel pressure reg).  Follow the hoses and see what it is connected too.

6. Yes, it will improve how it drives when cruising.  There is a lot more to it but for a stock engine definitely.

7.I think it supposed to have a dual return spring, if one breaks then it has a back up, having a stuck open throttle is not a good thing!

I’ll leave this here for inspiration

Is the unit designed to work with regular globes and/or LED’s?

 

Maybe you need to add a small resistor into each LED circuit to induce a load like a regular globe?

LOL,  this is why I shouldn’t reply to posts when coming off night shifts…….

 

I already have some black VHT engine enamel sitting on the shelf

Somewhere on or near the carby would be ideal.

Fuel reg depends on the pump/supply side.

They are known as a Hobbs switch.  What are you trying to achieve?

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Try extending the LED earths wire to the same point as the main unit, to eliminate the possibility of a ground loop.
