A tale as old as time, I cracked a piston in my LBZ (#4) I got it pulled, tore down, and my block, heads, and crank sent to the machine shop. I was dyno tuned at 510hp and 1,169tq all on stock internals. Wasn’t always on Tune 5 but lasted significantly longer than expected. My original plan for the crank, was to have it Keyed and an Alt firing camshaft installed. But I’ve recently been reading a lot on that still not being enough. I’m looking to make 650 when the build is done, should I just go with the Callie’s crank?
