Have just had the 202 removed  from my pre 78  torana  and found it was cracked in 3 places on the manifold side of the block  so am going to re-block the  engine  . This engine was built originally by Brough race engines  probably 20 years ago approx and was fitted with a roller cam and lifters  using bronze sleeved lifter bores  .  I also  had a roller cammed  202  built for me years ago and that engine also was fitted with bronze lifter sleeves  .

 

I have just half taken apart a 186 fitted with a 235 stroker kit  and roller cam  , but  there  are no bronze sleeves in this  ;  these  cam followers run directly in the original engines  cast iron  lifter bores .

 

Been quoted between  2-3000$$$  to have a block machined  and bronze sleeves  fitted  ,  so  is there any  advantage in going this way instead  of leaving the lifter bores standard  ?

 

Also..................is it possible to line bore a 186 crankshaft tunnel to take a 202   crankshaft ?  .............l have a brand new/unused 186  block .

You can grind the mains down on a 202 crank, potentially easier.

Must be a reason though why they went up in journal size when the 202 was introduced  .

Maybe. Chevrolet did it with a 400 too but people have been grinding those down in size for years to go into a 392/327/350 block to replicate Chevy’s 377 from 1962-3. And making big power out of them.
