just wondering what a Siamese block is.

 

the bores are connected inside the water jacket.
There is no space between them. Usually the factory blocks have space between them.

 

so is this better or does it reduce cooling efficiency?

 

Well the block is definetley alot stiffer and the bores are way thicker but not sure of the cooling. I know the water just goes to the back of the block and up into the heads and than back to the rad.

 

BTW Im looking at a 5th ave, decent condition for about 700$

 

i love mine. its one of the few cars i feel comfortable in since im 6'4 and weigh 302lbs. lots of room, good in snow, can be made faster. not necessarily fast but faster. they also ride quite nice. im looking for a truck now because i like to hunt and fish a lot and this car isnt going to go where i want to go.
