Do I have to have aftermarket pistons?

[slosh]

Trying to get a motor and tranny package together for over the winter and I have a couple questions.

1. Will stock LB7 pistons work in a lbz/lmm? Is there a considerable advantage for using aftermarket pistons cut and coated compared to buying a used set of pistons and having them cut and coated? Do the aftermarket ones help with the heat within the motor? I heard stock LB7 will hold up to 800-850hp

2. Im shooting for 650-700 rwhp should the rods or pistons be replaced at the same time or does one take priority over the other.

*Mind you the hp level will not be a DD level. I plan on having an EFI 5 position switch and that will be the "hot" tune. 450-500 will be the dd tune.

truck is a weekend truck. no pulls, drags, dd, or trailer puller.

So why build the motor?

I would do everything at once if you plan to do both rods and pistons.

I just want a fast play truck. The hp level I want to be at wouldnt I have to ad some insurance and build the motor? Any help you can give me is appreciatd :thumb:

I would think a set of lb7 pistons would work fine for what you want. Having them cut and coated should help even more.

What kinda setup u going to run? Single, twins?

 

[slosh]

Twins or possibly a triple setup. Built tranny, lift pump, gauges, etc. Will the lb7 pistons be a direct drop in or do they have to be worked a little for them to fit in a lbz/lmm? I'm guessing the top part of the piston is ceramic and the skirt is Teflon?

What specs do I have to have the pistons cut at? I assume delipped means the same thing as cutting a piston?
