Perhaps not applicable here, but wondering if there's still any debate with regard to cast versus forged pistons? :unsure:

There's a debate about everything where you have a choice!! Sheesh, I've heard there's even a debate on whether or not I'm good looking :P

Guess I'm recalling the cast vs forged mostly with regard to stock sizes. Perhaps all the large bore aftermarket pistons are forged.

if i had my choice, i would have forged....example
my marauder has a 4.6 with doulble overhead cams...stock with cast pistons....the same motor in a cobra mustang with a supercharger comes with forged pistons....i priced out a rebuild of my motor
for shits and giggles....the quotes i got all included forged pistons.....cast wasnt even an option....my mtc s going in my bike are forged....
gotta be a reason......

Summary
To sum up, the cast piston is light and very dimensionally stable. It is found in high-rpm mass-produced engines that are not subject to modification or prone to detonation. The piston is however fairly brittle, and the cost of its manufacture has limited its availablity outside the OEM sources and applications. On the other hand, the forged piston is inherently heavy and less dimensionally stable. It is a good choice for engines in which detonation is probable, and its wide availability has made it the choice of engine modifiers. The special demands of these end users has given the forged piston its own niche in the powersports market. The next time someone tells you how superior one piston type is over another, tell them the truth. Because, as Paul Harvey likes to say, "Now you know the rest of the story." Hold the fries, please.

Here at LCE, the philosophy is quit simple. The choice between using a cast piston or a forged piston is dictated by the application. If you plan on running normal octane gas and it falls into our “street” application, we recommend using the cast aluminum pistons. If you plan on using high octane, high compression or high boost for your application, then we recommend using a forged aluminum piston.

it depends on what you are trying to do with the motor,if its something running under a lot of boost like a blown,turbo or nitrous motor id say go with forged pistons.but if you really want to get crazy you can start talking about what the forging is made from was the billet cast or forged that the piston is punched out of?ive seen many stock pistons subjected to things well above and beyond what i would expect them to hold up to.its safe to say people have been doing things that far exceed what MOST people on here would ever subject either type of piston to for years and will continue to do so for years.

Billet aluminum is used solely for extrusion, it's a step in the extrusion process (precursor actually). There is no such thing as Billet Aluminum whatever, no billet aluminum heads/blocks/cranks/anything. It's all a marketing gimmick that has made fools of a bunch of people. Walk into a machine shop and tell the machinist that you want something made out of "billet aluminum", his first thought is "Ka-ching! This guys an idiot so I can quadruple my normal price for aluminum by calling it "Billet"!" .
you can start talking about what the forging is made from was the billet cast or forged that the piston is punched out of?i

Don't know what to say about that one, can't parse it so it makes any sense :unsure:

Both Wiseco and MTC are forged.

im referring to the chunk of material the part is forged from to begin with,i guess you could call it an ingot.(spell check :laugh: )i guess most people consider 3 basic manufacturing processes.forging by beating something with a lot of force to make a desired shape,casting by pouring molten material into a mold to achieve desired shape or by carving chunks out of a solid piece of material (aka billet)which is actually weaker thana forging according to some but stronger according to others;)
