it almost seems pointless to run lml pistons in a engine build think about this most of us keep pushing and tinkering on our trucks so y spend a fair amount of money on rods machine work and so on and then put lml pistons into it you may save some money but what if one cracks then what did you really save when you could of just ran a good quality piston from day one and for everyone saying all i want is a xxxhp you probably said that when u first got efi live and look how long it took before u wanted more
couldnt agree more rather be safe then sorry but its your choice :thumb: the way i see which some may disagree peace of mind is worth more then anything
That's the problem, there is no "peace of mind" piston out there that has piston cooling oil passages that has proven any better. Or at least what most think, many have cracked Mahle Race Cast... Only ones with no known failures currently are Fingers Oval Mahle cast, and lml's that I know of. And I wouldn't put forged any brand in a daily driver 1000hp+ twins or triple truck that I intend to put 10,000+ miles a year and tow at 20,000+ lb gross on a normal basis...
If I did it again, I would use Fingers cast from Mark's results, but others feel there isn't enough sets out there proving themselves knocking on the 1000+ hp mark on occasion.
What does a brand new set of lml pistons cost? I assume oval cast are around $1600-$1800? I could be wrong on that, but lml's would have to be dirt cheap to justify $800 in rod machining, like $50 a hole with rings. Because at $400+$800, it would have to be a damn good amount saved to justify making a one off set of rods, However, if they were proven strong enough aluminium rods can be built dirt cheap compared to a saet of Carillos, Crowers, or Howards. My 65 Malibu with aluminum rods, lml pistons, big air, big fuel would be a fun 5,000 mile a year car and toy.
I am however, not a fan of aluminium rods in my diesel pulling application, because I feel we lug the engine too much at the big end, and the surging and loading/unloading the engine does during a pass...
