Anyone running one of these? I'd like to hear what kind of power people have made with them. I have one bored and stroked to 333 ci, ( 3.25 x 4.040), running 15 psi. with a T-trim, just put the rotating assembly back together after burning up a piston. Think I burned it from running stale fuel, sits a lot, possibly clogged an injector, #8. These blocks were rated at 425 flywheel hp, and mine makes around 675. It went about 12,000 miles over ten years, was beat without mercy for almost all of those miles. I regularly spun it up to 7000 rpm. It has an Eagle 4340 crank with H-beam rods, main and rocker girdles, 1/2" head studs, and ARP throughout, and is well balanced. I always figured I was pushing my luck, but in the end it wasn't the block that failed. Even though it seemed to like high revs peak power was around 5900, and now im going to limit it to 6000. Anyone have experience with this block?
