I have a gsr block with GE sleeves, 83mm, and deck extension, 8.9inch or 226mm deck height. This makes it the same height as a Dart tall block. I have an LS crank that will be the heart of the block build.

With some help, I'm going to build this shortblock myself but what I need to know is what rods and pistons to purchase. Through some searching, I've found a Long Rod at 95mm by Eagle that fits LS crank journal. These are advertised as fitting a b series block with deck extension. Then, if i use these rods, what pistons, could I just buy 83mm LS pistons by CP? Or will customs pistons have to be made?

LS crank+eagle long rod, 95mm=1.70 r/s ratio.

If anyone can set this motor up with rods and pistons then it will be greatly appreciated.

hey man, i was thinking the same thing...where did u get your deck plate at? I was thinking of making one, but i thought it would be easier to find the piston and rod combo, let me know of your progress, cause im about to pull my motor apart in about a week...good luck
