Engine upgrade

This is one of those situations / jobs where as i have said in the past the good old house hold vacuum cleaner comes in handy . Although most of you guys wouldn't know where to find said machine :? :LOL:

Ive got a "Nilfisk" for the P6 only and the misses is allowed to borrow it ,if hers upstairs overheats from too much use !!.

Oi!! Chaps!! Lets all get our streotyping banter out of our systems elsewhere and get back to V8's, shall we!

Chris, it was only intended as a light hearted response to Stina's, I'm sure, similarly light hearted jibe. That said, I don't want to cause any offence or moderator consternation. So, please feel free to delete my post.
 
Woah , i was just havin a bit if fun , ( if you all could see the state of my carpets you'd see what i mean :LOL: ) Carpets in house that is , carpets in car are immaculate , Any hoo , back to the engine discussions , ( and me beer :D )

I dont think there was anything that could be construed as hurtful to anyone so reckon you were a bit sledghammer on that nut .
Interesting to see some of us have a house vacuum and a separate car vacuum .Im capable on both varieties .
You are right about the " getting back to V8's "
Ive been enjoying this thread immensely , as I am looking at an engine upgrade like this myself . Not that my P6 needs it right now .
I want to feel a bit more oomph low down in my old age . [sorry - double entonde ]
It seems a fairly easy and moderately cheap way to go .
Moderate on Chris you are a good man and have a fine line to tread sometimes .
I enjoy all aspects on this forum and apologies if toes were stood on

Thanks guys! The clue is in the posting time. I haven't got a sense of humour when I've been up since 05:30 getting ready for a committee meeting! I've put that right with a nice glass of something cold and white, now. 8) 8) 8)

Hi all .
Ordered a cam and lifters (3.9) , and rocker gear/shafts from V8 tuner (Paul , spot on guy ,very helpful . )
Not ready to go just yet , few more bits to sort first . Planning on building up the heads with new rocker gear , and manifolds next weekend .
Couple of questions .
1) The "S" exhaust manifolds are bigger than the Auto ones ( obviously the reason i want to fit them ) They fit into my down pipes nicely , but the clamps that hold down pipe to manifold have smaller hole centers for the auto manifolds ( the rounded off triangular things with big hole for pipe and three stud holes . Their is enough material to elongate the stud holes and get them to fit , but can i buy the "S" ones any where ? ( Don't know if that makes sense without a pic :? )
2) Cam comes with either an additive or paste , can't remember which until it turns up tomorrow :oops: Any hoo , what other lube is recommended for assembly of other bits , rockers , push rods etc ? In the past i've just coated parts in engine oil . I've looked up graphogen lube , but it seems very expensive , If i need it that's fine , can any one recommend one , or a link ?
3) What size are the head bolts (socket size) ? I know i've had them off before but want to order up a nice heavy duty impact socket for my breaker bar .
That's all for now , nite nite :D

How would you fit them to the pipes if you did get them?

5/8" AF, but you won't get an impact socket on all of the 14 bolts, for the others you'll need a good quality thin walled socket.

Think i know where your coming from . Right hand one has the removable down pipe so that's easy , left hand one i'd cut in half , fit round pipe then weld back up . Think this is what you mean ? The down pipes fit nicely into the manifolds , the difference in size of manifold being taken up with the spherical type joint .
Other than the correct bits i can elongate the holes , but rather not .
Graphogen paste it is then , Does it matter which ?
:D

It is indeed.

I think that would be an easier option.

AFAIK there's only one sort. It always came in a yellow toothpaste tube.
 
Somewhere on here is a thread on the sequence to torque down the cylinder heads , and where to stop with the outer row of bolts . Can anyone find it ? Also a guy on the V8 forum said to leave them out completely , just locktite them in finger tight if i don't want to leave empty holes , his reasoning being they were deleted on the later heads any hoo .
Thoughts ?
 
I think Harvey said you only need to worry with composite gaskets. I left the outer row at 20lbft on mine without issue.

If you look at harvey's sticky about his v8 fact sheet i think it says on there.

Applicable for tin gaskets, bolts are high tensile.

Thanks Ron . That's the official stand point then . What do we all think about leaving the outer row looser , or even delete all together ?
 
As you say stina there is a view with some rover engine rebuild sites advocating leave out the outer row and one american rover v8 engine site i saw said they found no harm omitting the outer row (I've lost the site but will reference it if i find it again) and as later engines have them omitted I can't see it being a problem if they are left off. I am tending to leave them off on my rebuild primarily because I will be fitting arp studs which get torqued to 80ft/lbs, so i don't want to introduce distortion by also having the outer row done up as well, why they are there in the first place without having an opposite placed bolt to counter any distortion is a mystery unless it's just a carry over from the buick design.
 
O.K seems like devided opinion on the head bolts , thought it might be , their's probably no definitive answer to that one :?
Next question , what spark plugs do i need for the SD1 heads ? I ask because i see listings on ebay for SD1 which i know are for the P6 engine , and i know they don't use the same plug . Does any one have the plug number for Champion and NGK ?
Cheers .
 
I think most people on the V8forum advocate fitting them at a lower torque than specified, mainly to keep the holes from filling up with crud.
