If you eally want to get into it, You can buy some books about building a SBC (another search that would yeild a good listing ), Yurick and Lingenfelter are two that I have referenced allot, so you understand the effects of rods, and also the designs, H-Beam, I-Beam etc. weight locatin Rod vrs Pistion, Rod lenght effect on Torque vrs RPM, And after all that reading,
But I will say that rod lenght doesn't have a clear one is bette then the other, many builders differ on opinion.

thanks for the info, i just went out and purchased a builders book and i found one that my dad had and im comparing the old school ways to what we have now, i spoke with my machine shop and he gave me some tips as well but all in all it looks like machine work to the block including bearings and putting the pins in the pistons, having them balanced and blueprinted with run me about 650.00
