best rotating assy for blown ls2??? building an alum block ls2 and wondering what is the best components for the bottom end. looking at the callies dragonslayer and compstar cranks. will the lighter weigh of the dragonslayer crank sacrifice durability with the blower (F1R procharger) hanging off the front? and will the compstart crank hold up to 1000+ hp??? also wondering which engine size would be better suited for the combo short stroke 364? or a 4.000" stroke 402? not looking for the cheapest parts but i only want to purchase these once. the car is an 81 Z28 with the ls2 mentioned above with L92's and a cog drive f1r. shooting for mid to low 9's. thanks for the help

Both will work fine but 402 will have a lil more power and make more low end obviously due to larger engine size. Only the 2.000 DS is really lighter and I would run the larger 2.100 for a big blower as the blower will be the main thing making the power plus you are driving it off the front of that thing so I would keep the rods as big as you could.
