Default diamond vs weisco

let me start off by saying this may be covered in here already, but i could not find anything with the search, just wanting some people opinions what they think would be better for my setup. Thank you for any input. all is appreciated.

I have a 6.0 iron block, bored 4.030 with eagle 4 inch crank, scat 6.125 rods, plan on doing a ls3/l92 heads with carb style intake and a largeish shot(200-300) using a acufab style 4barrel throttle body. so my question is, which pistons do people recommend, have been referred to both of them, does anyone have a preference over the other and why? the weiscos i am looking at are k646x3's. i havent looked into diamonds to see exactly what their part number is. but would want them around the same spec. Again all help is appreciated.

I prefer the Wisecos because the staff always takes good care of me and the price is right, which usually includes rings. I've never had a problem with Diamond, but have personally bought about fifty sets of wisecos and two diamonds.

You can do directly from them or a sponsor/vendor on here. You cant go wrong with either brand though. Both are too notch!

I recently purchased custom pistons through Wiseco, and like Whistler said, they have good customer service. I needed some coated wrist pins, and they put me in contact with a vendor.
