11 years ago i bought an all new 540 shortblock built for truck pulling...Siamese Mega Block, Callies 4.5, Wiseco pistons, and Eagle 7.1 rods (of all things to skimp on, rods should be the last). These rods are rated for 750hp. After the motor was pulled for body restoration, the standard 440-1s that i have run on the street were 345-CNCed. That, along with the appropriate solid roller cam, have put the HP level in the 850-900 range (Mike @ Muscle Motors rough guesstimate). Compression is 13.5:1. I would feel more at ease with 1000+ HP rods/bolts. Steel preferred, street driven. Suggestions??..or is that not enough info to go off of??

Open to main stud suggestions as well.

Thanks!
