Rods/Pistons? Doing some re-search here on some rods/pistons needing everyones input.
1. Its only gonna be a street car I might take down to the drag strip every once and awhile.
2. SCCA events I might run it around the road course a couple times.
Anyways im planing on doing an LE2 set up and I wanted to build just a little bit better bottom end, I heard I can keep my stock crank I was just wanting to know what Rods/Pistons I should go with?
Im gonna bore it out to a 355 since she has 103K on it, just to be safe, and ill have it balanced and blue printed once I get all the parts.
Thanks for any help

Really you would be fine with a stock bottem end. If you wanted to do a little more, you could get some ARP rod bolts and main studs and have the rotating assembly balanced.
How much money are you willing to spend..
Me personally I would go with a set of Eagle 4340 Forged Rods with ARP Bolts, and look for some Forged Pistons, preferably light-weight ones. Then get you a set of good Bearings in there. Stock Crank is fine. After you get all that, get it Balanced.
Build it once, build it right.

if it were me, I'd probably go with a set of 4340 I-beam rods, with bushed ends for full-floating use, as well as cap-screws instead of bolts/nuts. as well as a good quality forged piston (JE, SRP, Diamond, Weisco, etc...)
H-beams for an all-motor setup are probably a little excessive, as well as a little heavy. forged I-beams are WAY stronger than what you will need, and lighter to boot (a little easier to balance) than H-beams. A stock crank will do everything you want so long as you balance it properly.
rods/pistons are basically what I'll do when I build a motor as well.

From what I have seen, some of the H-Beams are not that heavy either. I put the Eagle 4340 H-Beam's in my 402, and they weighed in at 600g, and felt really light. It depends on what you are doin with it I guess..

Yeah i read that, Eagles H-beams are 630 grams and there I-beams are 560 Grams.
Also isnt the LT1 a 5.7 Stroke? Its been a really long time since ive build an engine

Why the 6.0 rods rather than the 5.7 Rods? Also why Scat? From what ive been told they arnt the best of rods?

The 6.0 rods give the motor a little better geometry. the scat rods are actually pretty good with the 7/16 rod bolts I personally would never touch the eagle-I beams. if you want to get into bigger $$ manley makes a H-beam that weights 600 grams runs about $600 though
