I need to mod the elbow for it to fit in the rush chassis so I might as well try and make it better.
Can I get rid of the web from the middle ?
Cheers,

if the only problem with std bolts is head lift over time due to bolt stretch, surely it's better to use them and replace gaskets periodically than have a stonger clamp that damages the block?

Its all a personal opinion norris will map on l6 but no one else will, 200 block is better to 1 man and 205 is better to the next man. End of the day you hear so many storys about so many different things its best to just go with what you think and get on with it and if it breaks it breaks tuff shit imo.

ARP Stud and Nuts are shit end of, no idea how the people that use them get away with it tbh, standard bolts are miles better, long studding is the correct way to being doing things IMO, you don't hear of many proper Mountune engines failing like people mention do you ?
I think half the problem is that as good as some tuners are I don't personally believe they or whoever they use for machining are doing the job correctly if we are seeing such bad failures.
I wouldn't mind having a word with anyone that worked for the Ford wrc team when they were running the Escort as I very much doubt many of those engines were busting 200 blocks that often
If i was building a 500hp engine I wouldn't be starting with a shonky old 205 block and some micky mouse headbolts, 500bhp is not cheap and cant be done cheaply either so be prepared to open your wallet.
Personally I would get on the phone to a few companies who can long stud blocks and listen to what they have to say about it and blocks failing rather than a bunch of guys off a forum who 50% of cant guarantee you anything.

glad mike mentioned C/R................and the reason "people" wont map "dickos" car is because it's an "uncertain engine"............little bit of this n that....................this is why Ahmed said NO..........if it went bang.....who would u blaime...........................

Mark Shead originally mapped my engine but didnt build it.
He did need to know EXACTLY the spec of head, cams and comp ratio tho.
What does Dicko NOT know about his engine?

seems to me no one actually KNOWS what causes blocks to crack around the bolt holes,i know its easier said than done but if someone was to do some research into this issue we would be a step closer to solving it with out having to long stud the block.
i cant confess to know everything and i dont know the full reason/advantage of using long studs but cracking blocks could be the reason mountune developed the long stud in the first place.in other words if your worried about your block cracking get it long studded,but this only a cure of 1 problem!lol
as far as 200/205 blocks goes is there a difference in the bolt holes?as i'm guessing not,this would explian why both blocks have a problem with cracking without long studs,i was always under the impression the only difference was the 200 has thicker bores,but i have no factual basis on that.
i am going to use the arp stud and nut kit simply because i have bought it already but reading this thread it seems spending time making sure all available thread is made use of when installing them,essential.
hopefully i wont learn the expensive way,lol!

Personaly I think a well prepped and fully seasoned (shame the old btcc cars couldnt get hold of 20yr old 205 blocks at the time eh....works for yank drag cars with their V8's!) 205 block can handle alot more power nowadays than when they were new...only if the rest of the engine is working 100% as a complete package mind.

Its not all to do with power either, mine was a stage 3 engine, built from a new block and had probably covered around 5k when I removed the head to find the block cracked.
You wouldn't think stage 3 would kill a new block

I don't think MSD, NMS, MAD or Julian Godfrey, or Harvey Gibbs would reccomend using them which tells you all you need to know.

Sod all to do with weaknesses of the 205 block in its native 2wd guise.

stu, wot sort of c/r do u need to run light blues or maybe greys on a 205 block?i only ask as my engine has been rebuilt but i aint got a clue what the c/r is i have receipts saying the pistons have been machained etc?i am runnin 803s at the mo but fancy more power?wot would u recommend?i would get her lived mapped(git it done on stage 3 even tho lots of people said not needed as its only a mild tune!)

Im still backing the theory that a well prepped 205 block can take it.......imo if its lasted this long then its gotta be a good un and after 20yrs the casting has gotta be well settled by now so its going to be stronger than it was when new.
What are these ere norweigan (sp?) lot doing with concret anyhows?? Im abit dubious about nipping into my local B&Q for a YB block strengthening kit but it seems to work for them?
If cracking is mainly a result of block flex then would a thicker walled sump also help the problem.....I presume one of Fords reasonings for going from the pinto's tin sump to the alloy sump was to help with block rigidity....so why not take that a stage futher? Or maybe a beefed up gearbox bell housing, as that would form a very large bolt on block brace??

Too many posts.. I need a life!!
if u want a RELIABLE 500 plus im sure a 200 block we need saucing especially if the 205 block has been rebored more than once?(cylinder walls to near to water ways and excess cylinder pressure will crack your bores)
