If you use the stock piston's then you will end up useing part # 2-ICR6100-944P. If you choose to buy new pistons then you will use either 2-ICR6100-927 or 2-ICR6125-7/16.

Thanks for so much help 97bird, what would you suggest as a good piston for the stock bore, with stock L92 heads. Something strong, not too expensive, and able to produce good compression for a street motor.

I found three companies that make a piston to fit your application. They all use the 6.125" long connecting rod (2-ICR6125-7/16). The most expensive will probably be Diamond, part # 11541, I did a quick search and the cheapest that I had seen was $627.99 w/o piston rings. The next was a Weisco part # K398XS that comes with rings for the year 2009 according to thier website, but I was unable to find internet pricing for it. The last piston part number that I have will probably be the cheapest of the three. Mahle makes a piston & ring kit part # L92314000F04, but again I was unable to find internet pricing on it. I would call several of the sponsors and try to get availability & pricing for them. Sorry I couldn't find more info for you but I'm out of energy after putting a 20 hr. day in.

Ok thanks guys, I am not planning nitrous/boost yet, I just don't want to break stock pistons. Would it be totally worthless to use new rods with the original pistons?

I wouldnt run boost on stock pistons on rods but i would say go ahead and run NA stock rods and pistons. My engine took a hit in the oil pan when i had bought it. Timing cover was smashed, oil all leaked out. Figured it was shot but stuck it in anyway. I did a compresions test 7 cylinders were 0-30 pise and 1 was 130psi. I installed all my stuff anyway let it heat cycle and today every cylinder compression test at 165psi within 2 psi. It's really NOT that hard to pull an engine and rebuild is especially in your truck.
These guys are usually talking about being in 4th gens or vettes where engine removal can be a pain in the ***. I can remove the engine in my firebid in less than an hour if i had to. I know it might be double work but if you dont have the money, you dont have the money man.

Ya I don't mind swingin the engine in and out, the bay in my truck is cavernous. Plus, if I am putting something better back in, I am more than happy to yank it out =]
