I’m running Callie’s rods in mine now. We’ve pushed the Callie’s rods in our race truck to 1500+ with no issues. The Callie’s rods are a great alternative. From what I understand the only reason they’re cheaper is they aren’t final machines to look pretty, which may give them some slightly weaker spots, but overall doesn’t hurt, just a little lower max hp rating.
Don’t know if I can help too much on the cam, either one plan on valve reliefs in the pistons, I’m running a kdd stage 2, and it towed really well, although so far the one time I’ve towed with it, it wasn’t a tough tow by any means, fairly flat, but pretty heavy. I would say based on all the engine builders recommendations, if you ever plan on towing, just go with a stage 2.
No one has really done back to back cam testing with no other changes, as cams are such a mfer to change just for science so we don’t really have an actual cam a does this at this, cam b does this, and cam c this. There is theoretical based on the lift/head flow/ duration numbers, but as everyone knows numbers and real world are 2 completely different things.
I would recommend kill devil for your parts, and give ‘em a holler for recommendations on cam size and what not.
