im looking to build a mild (650-700) motor for my truck. i have a lb7 motor i just picked up to build the short block for my truck. i plan on using cut lb7 pistons, decent rods, head studs, valve springs, and keying the crank and cam. what is an affordable rod choice to go with? i see most people use carrilos but i was thinking of trying the brian crower or the manley rods.
LLY: what rods to use
- Thread starter wfc09
- Start date
So how come when Ive asked before about using LBZ/LMM rods in my LLY to reach 650-700hp, people have shot it down?
Is 650-700hp that much of an unreliable hp amount on near stock internals?
Sorry to sidetrack the thread OP
If my truck stayed at 650rwhp I would use LBZ rods. The problem is, you want more, and more. That's why most say just go straight to carrillos.
LBZ/LMM rods are fine for 650-700rwhp. The problem is you will always want a little more HP once you have it up and running good then you will look back and say man i should've put some better rods in it. At min i would use a good set of rods in a mild build
I put lbz rods in my lly when I had it gone through. Ran it on a 650hp tune for 35k miles with over half of that towing. Then I cracked a piston. I think the lbz rods are fine for the 650 mark. Problem is most people won't be satisfied to stay there.
I guess if thats where OP wants to stay power wise, then him and I have similar goals.
Though, would LML rods be an even better choice than LBZ rods and pistons?

Go bigger or stay stock. Don't do a "motor build" for a hp number that people have achieved on stock internals.
I know this has been beat to death, but I figured if we're discussing a budget, mild build could one reuse stock pushrods and springs? If you were only shooting for 650hp and weren't planning on revving the engine way up would stock springs and stock solid pushrods be alright?
Hap calculators put my truck aroujd 750hp and I shit a rod out of the block after 10k or so of beating on it.
It's amazing what the LML rods are holding up to. I wonder if anyone has tried LML rods with LB7 cut pistons.
