308 Blue Motor Rebuild
I bought a rebuild kit for my 308 but the bloke asked me for the ring size and the bearing sizes. i was wondering if anyone would know these because i am not stripping down my engine to find out.

LOL sorry mate you're never going to know till you pull it down and measure it.
Hiow were you p[lanning on using the rebuild kit if you dont strip it down?
They need to know otherwise you wont be able to buy it.
It needs to be stripped bores measure to work out whether its stock bore 20,40, or 60 thou oversized if its 60 thou over already you'd better hope theyre in good nick otherwise the block will need re-sleeving.
The same goes for the crank it needs to be measured to see if has been ground before so they can give you the right size bearings.
Unless you can say for 100% cetainity thats its a stock virgin bore motor then you can can order the right size then. Oh but wait you wont know how much wear there is, if you did you could order +5 rings or file backs or even +1 bearings or something. Once again you going to need to measure it.
Something if you dont know what your doing (as it seems by your post) that your best leaving to a professional

Seriously though, its almost impossible to 'know' unless you have had the car from new, know how much you'll be boring it, know the condition of all the internals and know the entire history of the engine.
Bores could be oversize, crank ground - undersize, possibilities are endless
Edit: Ehh beat me to it!!
i know i need to strip it down to rebuild it. the car is my get around car at the moment and i was unsure of the measurements and i didnt want to pull it down to just to get measurements. now that i know that wear comes into play i will have to pull it apart just to measure it then put it back together to drive it again. thank you for the help but i wish you could be nicer when helping people. instead of being a know-it-all with an attitude of a pig, try and say it in a nice way. oh, and my brother is a mechanic and he will be helping me, i am doing it myself to save money and to be a part of my cars restoration. i have got a fair amount of knowledge about cars, and i learnt these things from DOING them, so please do not criticize someone who is willing to give something a go.

I've got a VQ block here with a good bore if you want it. Saves pulling your old motor out. PM me if interested.
my 308 is carbied not fuel injected. im restoring a VH SL/E. thanks heaps though, just out of interest what would you want for it? might come in handy later on, and where abouts are you?

It's just the block mate, you can put carby heads on it. ( although I do have VN heads as well).
$250 for the block, I've debured the block lightly as well.
where abouts do you live? this will make it a bit easier if i buy it off you. when you say block that also means no heads yeah. the efi heads will be useless to me thats all. i will definitely look into getting the block off you though.

Oh sorry, I'm in Ardmona, about 10mins west of Shepparton.
Yeah just the block no heads, I have the heads But they're worth as much as the block lol.

Sorry about being condecending i suggest you hold off buying a rebuild kit till your ready to pull it down thenif your doign up an sl/e it might be best if you kept the original motor as it'd be worth more to a collector or anyone that likes classics compared to putting a late model block in it.

Rebuild them both?
Saves having the car off the road.

So who are you speaking to? Its nice/polite to address some one you are talking to, also to avoid any confusion.
If you weren't talking to me, then my apologies for what I'm going to say next, but if you were talking to me, then get ####ed.
If your brother is any sort of Mechanic, he would know that most of the time, at least 'some' of the engine would be best suited to some machining - if nothing else, a nice cross hatch on the bores wouldn't go astray.
But ohh wait, you pull it down, see theres a bearing thats worn, cranks got a bit of wear in it, so then theres machine time - which is plenty of time to order the correct bearings/rings.
Neither Pub's post nor mine, were IMO "know-it-all with an attitude of a pig"
Both were informative, in a non judgemental way, offering our opinions.
true, it already is running a mild cam, dont ask me what it is because i bought it like this. the only reason why i want to rebuild is because it is using way to much oil and losing power(possibly the carby is rooted as well).
yours was not what i was talking about, Pubs i found a little rude and made me feel like a dumbarse( i am not, i just dont have much experience in rebuilding engines). i probably shouldve asked my brother or my uncle instead. what was posted basically said to me was dont even try to do it because you will f**k it up. im not replying to anything else to do with this post as the reason i posted this thread was to get some information. thank you all for your information, it has been helpful
SSM11K
lol, well in that case then, ignore the "get ####ed" bit
Nah, definately keep asking here, thats how the forum works, if you don't know - ask!
Sometimes you've gotta take whats said "with a grain of salt" though, most people don't mean to make you feel like a dumbarse, just its seems straight forward to them?
Thing with 'writing' the response in text/writing, as apposed to speaking it, some things can come off/be interpreted a little harsher than they are intended.

Yep, very true. You've gotta exagerate on the internet. If you're being nice be over nice.

Dude, thats the way it is. I've been told many a time not to bother with painting a car, because if you don't know the 'right way' to do the job, it can turn into a real nightmare and cost you more than if you just got the pro's to do it to begin with.
Building an engine is the same, if things aren't done right, somethings going to let go. Maybe ruining the block, meaning its going to cost more than if you got the pro's to do it originally.

Zactly,

The only way to learn is to make mistakes.
Cheque book racers are the lowest common denominator. I'd rather have a 250hp motor I've built myself then a 500hp motor that I paid 20k for.
Same goes for painting too.
SSM11K
Same.
But, I do all the work on our cars, anything, even 'specialists jobs' like rebuilding auto trans, heads, etc...
Although, IMO encouraging some one to go to a specialist to have a basic rebuild done, rather than encouraging them to do it themselves, as they might not have the neccessary knowledge to be able to complete such a 'specialist task' is a lot different to a cheque book racer, buying his way, every step.
And I'm ####ing spewing I didn't paint the ####er now...

Eh I would encourage them to get accurate info.
Go speak to the pro's most of them are more then willing to correct you if you're wrong (especially if you buy parts from them

I did apologise for the way my attitude came across in the post but no matter how good of a mechanic you are there is very very few that know how to machine and engine . The assembly process isnt the hardest part as long as you follow instructions and do everything to the proper torque settings its all fairly basic.
Even with your brother or uncle helping your still going to have to outsource the machine and its best to wait till thats doen before you going buying a rebuild kit
