AES 390ci - Now with Callies Dragonslayer crankshaft
#223
When comparing the Original 390ci Kit and the New 390ci Kit, one has the 3.825 crank and the new kit has the 3.380 crank. What is different in the kit to offset the 0.025 Extra Stroke, Piston Comp Height or Rod Length ?

Im sure he will tell you they dont see a problem till over 1000hp. I will tell you what i did for strength and to avoid pushing water. Dragon slayer crank, ultra rods, no pins for the mains, O-ring block-receiver the heads, Clark Copper head gaskets. I dont think i will have any problems with 1100 hp.
If my set up was going to spend it's life at 1000+ i would have went with the LSX combo. In reality i will be at 800-900 hp.

The fix, LSX block. Siamese bores, billet caps, etc.
