Have thought about this and thats the power im after but do you think its possible to run 500bhp on a standard 205 block has anybody got this sort of power on a 205 block has been running 411bhp with no probs but would like some input cheers

 

Brom was running over 500 brake on a 205 block

 

Do you know if it was without any trouble and millage he got out of it

 

By bother for the price of a 200 block and the cost to prepare it, long stud etc etc

 

The reason i would like to try this is that i already have a mint 205 block on standard bore and many 200 blocks are not standard bore anymore and the ones that are make stupid money a standard 205 block must be stronger than a 0.5 200 block i would have thought

 

I would risk it if it was me mate.

 

You would risk it

 

 

 

Fook that.

Just buy a nice 200 block you tightarse !

Why bother risking it ?

 

What like you did

 

It wasn't new and thats where I learnt my lesson

Had I off got the block only I would easily seen the fault but as it was built up no one was to know it was put together by Stevie Wonder

 

Very true but what im getting at is there any proof that a 200 block is that much better just trying to get a feel what people think

 

I personally feel that a standard bore 200 block is better, once bored I have heard they are no better than a 205 block.

I don't know exactly what size bores weaken it though.

Long studded standard bore block "should" be bullet proof and although no one seemed to give me any answers on what caused mine to fail I am still very sure it was poorly built.

I dont believe for a min that they should fail and tbh Mike has already mentioned many time that ARP head studs are one of the reasons why they do

 

it makes fuck all difference in what block you use unless u longstud in that case itll need to be 200 because the waist is thicker so will take the longstud

there has been a few in the early days on 205 blocks at or just above 500 bhp that were reliable asmost 500 bhp engines but i would change the head bolts about every 5k because the yb is a floating head and lifts and moves about under high boost levels

 

id risk it mate mine should be around the 450bhp when ran in and mapped on a 205 block and will be more to come

 

Good info that Jay

 

cheers jonny the fact is 200 and the 205 give up in same place's front and water jacket to bolt hole (crack) or split a bore .

 

So it is possible that my block just failed then even though it wasn't very old.

Sadly that doesn't excuse the nice indents left in the head though

You say they split a bore but is that specific to both types of blocks or bored 200 blocks ?

 

Might just give it a go but if you dont longstud it what do you use

 

So because of that you would go along with it?

 

possibly id say a overbore is weaker this the reason why the likes of rod and mikeR use the uprated liners for added strengh for a over sized bore for reliability

 

Jonny my 200 block was just the same as yours mate i had it longstuded and han no problems at all still going strong

 

but if it is possible why not . i know your car is very well engineered but not everyone has the skill or the vast budget to build such a car

 

But why bother using an inferior base for an engine? If a 200 block was fortunes I could understand it!

 

Cheers mate, I've left it on a stand in my garage as I dont really want to look at it right now

I have been offered a long studded block though for sensible money that will take all my internals but I need to get mine checked first.

The fact mine has one liner is also putting me off using it too tbh.

Still think its risky using a 205 block for a 500hp build as its going to cost alot more than the rrp of a 200 block if it does fail and need rebuilding.

Do it right once and then you "should" be nice and safe withotu any worries
