3.0 PRV -B280E cams?

Coils on plugs is very easy and utterly reliable.
50mm IDA-3 look-alike throttle bodies can be had with internal injectors. Carburetors are such a pain compared with modern management. Programmable management will run exactly the way it is programmed to.
Where you can; let the bent six really yell! Just be sure you are OK with bearing speeds.
yes you cant compare injection with carburators, but fiddling with engines, building stuff is a part of the joy, i have for example a ferrari with 4x 42dceo weber and it works very well, and when you learned how to tune them it is not so difficult, but if you want tune and forget, webers are not for you.:), my english is nt so good and sometimes i dont understand, but bearing speeds?, if you mean size of pullys, yes it will be small size pullys.
 
i found a pair of heads from citroen xm, they are 3.0l liter heads, i have tryed to compare the heads on the photos and found 2 diffrenses, i will need to custom the cam cover, other then that it seams to be same as B280E

I also enjoyed getting Webers just so.... I didn’t enjoy carburetor icing! Driving along at (pick a steady speed) and it starts running strange or lift throttle and throttle is stuck in that position. Have to stomp on the gas to break up the ice on throttle plates. Happened all the time in (wet miserable) Washington State this time of year. Less often when warmer.
Your English is great. I know too many native English speakers who are not fluent in that tongue; and are utterly unable to write.
Yes; those Citroen heads are winners. Peugeot has many to choose from too. There are four valve heads out there.
 
im so excited and happy about a new tool that i have ordered from China, a wather polish machine, now a my aluminium parts will look like new.:)
i move clip when they test my machine in china, will arrive in 2 weeks, this was oftopic, but im gonna use it on engine parts.:D
when i look at the movie, it seams like they dont relly know how to use a water polish machine, 4 bar first sweep, 2 bar finishing sweep, and use glass balls 0.25mm, to ruff surface on video, probably wrong media in water, should be shiny, more like chrome finisch.
many items from china sux, but it is getting better and cheap, well we see.:)

A question John, i have ordered the heads and you never know how they have been beated upp, so probably need to flycut the head, do you know how mutch you can flycut it, the timining is not a issue, because i will have adjustibla camgerars, i have tryed to calculate the slack on chain, and that is almost not measurable and like 0.15mm should not be a problem?, the camcover will need to be machined, also i think i read about that you put some kind of selant between liners and block?, is this nessacery, my block liner surface is like new, and also new liners, i have read that liners should be 0,16-0,23 from block deck, is this correct info?

adjustable cam gears for the prv? im intrigued. whats he want for them? i was going to use offset keys on the crank to adjust the cam timing, but there's only so many options going that route.
the guy has not answered my yet, he is building a prv race engine for a Volvo FIA race car and have a lot to do, but i asked about the adjustable camgears and he make them from the original camgears, he told me this, -adjustable cam gears Make them on original wheels, took 295US last time. i think this is for a set, so around 300US+ you need to suply him with original camgears, anyway i will buy new camgears for him, if you are interessted i can help you to make contact with him or what is needed, but it will probably take some time.

one thing we need to have in mind is that dovel pin is on diffrent location between odd-fire and even-fire cam-gears, but maby this is not importen because you have the adjustment?, but if i have understand this correctly, the guy ho makes the race camshaft here in Sweden he make them for odd-fire engine, and if i want to use this odd-fire camshafts on my even-fire engine, i need to also use odd-fire camgears, is this correct?

i believe the manual says to avoid resurfacing the head, but of course now that these engines are 40 years old, thats almost impossible not to do. You can always adjust the cam timing with keys at the crank and/or your adjustable cam gears you were talking about. the biggest issue is once the head is resurfaced, now the timing cover sticks up above the head surface and your valve cover wont lay flat. either A have the same amount taken off the timing cover, or B use a thick bead of silicone to make a "ramp" to allow everything to seal afterward. I would take pictures from my manual, but i left it with the machinist working on my engine.
 
this appears to be the only picture i saved before handing off my manual. this is because i was looking at having liners made before decided to just have my current ones honed out a bit. there is a page on liner protrusion, but i don't have those numbers in front of me.

strange, this measurments is not like my B280E liners, look at photo, also my liners are on the way from holland, 93mm 3L.:)

weird, i am not sure what to say about that, unless there is a typo in my book? my manual is for the Eagle 3.0L - but the deck height is the same on all the blocks, so the liner length should be the same.
Until i get my engine and book back, I can't confirm or deny anything.

i told you not to resurfacing the head to mutch.:D
 
The liners has arrived, but it was supose to be 97.68mm as my volvo liners are, but they are 97,61, they where ice cold when they arrived -5c and then they measured 97.57, maby they need 24 hours to (grow), they have slowly grown 1/100mm every 2 hour.:), but for now they are 7/100mm smaller, i cant think of any reason that this small number will make any diffrans.EDIT, now it is 97.62, it grows, kind of remarkable.:)

a question, how mutch should the liners go over block surface, i found in a book that volvo says 0.16mm-0.23mm, i dont know if this was for the B28 engine or B280?
 
Ah, i thought I had this saved somewhere! This was in an email I sent to a company about getting shims re-produced. (which by the way is possible, but requires a minimum purchase). This is from my EP 3.0L book, I would imagine this would be applicable to you as well. NOTE - there is another spot that mentions no more than "X" amount of variance between the bank, but I don't have my book on me to find that right now as my machinist has it.

Many Many Thanx..:D
 
More liner protrusion means less squeeze on the rest of the head gasket which will make for pressurized oil finding its way to the heads leaking into coolant. .004” protrusion is plenty.
Skim the heads just enough to get a good sealing surface. Measure before and after thickness of heads and trim top of timing cover same.

I used Toyota’s black sealer at bottom of liner to block. Never an issue.
 
Next question, mutch to figure out, im about to make dry sump system so would like to know if someone have info about where to find dry sump oil pan?, or have info on how to build the oil sump?, or have one to sell.:), you can PM me if you dont want to talk about it here.
