Removed my engine Sunday and checked my 200 block number the one by the crank breather and it ends 91 is this a non turkish block then and does this figure relate to the build year?

 

what does it start with?

 

I believe 99 is the bogey prize

 

sorry got the number wrong its quite hard to make some digits out

think its

25D81

or


25091

 

so if its got no 99 im ok?

 

great thanks Dave

 

and I believe they are indeed the build year.

 

must be 91 at the end then chip, cheers fellas looks like i have a good block to start things off with then

 

IMO that your ok as all of the reported problem blocks have 99 on them.

Ive got one of the Tukish blocks.

From what I understand. These blocks are failing where power is being increased in excess of 550bhp with aggressive torque curves ? I remain to be corrected if I have been misinformed.

 

yes Dax its only effecting big power engines, i wont be exceeding the 450 BHP so doesnt realy matter but nice to know its a strong one.

 

I have an 200 block out here with a xx5991 number on it..
Is this an Turkish block? Because it has 99 in it but NOT 99 on the last 2 digits like said before on this page.
Anyone have an answer for me?

 

anybody?

 

Most are turkish blocks but the last 2 digits is the 99 batch which are weaker. Please be aware there are cars out there with over 600bhp on a 99 & still going strong. It wont see 700bhp though.

 

thanks MadRod mine has clearly not 99 in the last 2 digits but 91 as said before so mine block wouldn't be the weaker 99 batch 200 block right?
Looking for 450 bhp max.
