I have Eagle Rods 6.000" H-beam and Diamond piston 4.030 what is the suitable Crankshafts for that Rods and pistons. (LT1 Heads S2 In 2.00 / Ex 1.57)

 

Need to have the compression height specs for the pistons before we can determine what stroke of crank you need.

The compression height specs is 3.480

 

Nope!!

Compression height is the distance of the piston pin to the crown of the piston. If you know that, then you can figure out what stroke and rod length combination you can use with those pistons and your block.

3.48 = crank stroke
6.00 = rod length
9.025 = stock block deck height (distance from crank c/l to top of deck)

So to figure out the correct compression height would be the following formula:

3.48/2 = 1.74 (half of stroke length)

9.025 - 1.74 = 7.285 - 6" rod length = compression height of 1.285"

Obviously this compression height can vary based on actual deck height of the block you're using.
