What forged pistons/rods to use?
What forged pistons/rods to use? Over the past 6 months or so, I've been collecting parts for a front mount truck manifold setup. Originally I was going to go with a 5.3, but I recently got a good deal on a LQ4....too good to pass up. I'm weighing my options as to whether I should sell the 6.0 and use the $ to fund the 5.3 setup, or build a 370.
What pistons and rods are you guys using? I'm looking for something fairly affordable, as I'm only looking for 600rwhp or so. I'm debating running forged pistons and stock rods/crank, only upgrading to ARP hardware and new bearings. But, if the rods arent too terribly expensive, I may just upgrade them as well.
Also, what dish cc should I go with on the pistons? Stock CR seems to be 9.5:1.
Opinions? Any good vendor's selling forged pistons/rods?
Thanks

What heads are you planning on running and what block are you thinking. Those decisions need to be made first before you can pick a piston or set a compression ratio. As far as brands go, we have been running Callies crank and rods w/ Wiseco pistons and haven't had an issue w/ either. You could put a forged piston and rod on the stock crank and easily make the power you are looking for w/ minimal boost. The pistons and rods will be the same price w/ either block. You would just have to decide what way you want to go!

Sorry Jon, I should've specified. I am looking for piston/rod suggestions for the LQ4 iron block. Will be running the stock 317 heads, LS6 cam and springs, and stock LQ4 crank.

For what you are looking at I would go Callies Compstar crank and Compstar rods. On the pistons, Wiseco has a -11cc piston in a 4.030" bore w/ stock stroke. With a factory gasket that will have you down around 9:1 static compression. You can bring it up w/ running a thinner gasket or doing a slight mill on the heads. Let me know what you think or if you have any other questions and we'll get you fixed up!

i was thinking of just rod bolts but want to do this instead. i have a nice ball hone just gonna scuff up the bores like stated to seat the rings. not a big fan of diamond from my buick stuff so have to see what else for a stock bore is out there.
