No insult was intented, 1969 pistons are not the same as 2004 pistons.
The information I gave was not just for you as others may be interested also. It is pretty clear you have your mind already made up, and I have no interest in trying to change it.
I would suggest people who are interested, take a look at what OEMs use in racing and there own production high performance engines. I already gave a number of examples.
AutoZine Technical
Let me sum this up:
"3. Forged components
Forging seems very old-fashion, but there is still no alternative way to obtain high-strength yet lightweight parts without it. From Honda Type R to all exotic supercars, FORGED pistons, crankshaft and con-rods are commonly used."
"2) Heavier pistons: while Ferrari uses lightweight FORGED pistons and titanium connecting rods, the W8 can only seek more cost-effective method to cut weight from pistons."
Omega Pistons
Let me sum it up. "The cost of a die-cast piston is considerably less than that of FORGES but their use is limited to road going vehicles, vintage car clubs and motorcycle clubs. Having said that, we have produced Mini pistons (Mini Cooper) for both road and race applications using this process with excellent results."
These guys not only make forged but metal matrix as well
Accralite Pistons
Mr. Nixon, may know more than everyone on this board, or he may not, his web site is devoted to VINTAGE Honda motorcycles, mostly from the 70's.
More of the same: Ferrari F40
The FORGED pistons were redesigned to improve combustion efficiency, and the IHI turbochargers were water-cooled although the Behr intercoolers remained air-to-air. The large tube-steel exhaust system was improved, most notably with a revised wastegate, and by the inclusion of catalytic converters. A horizontally mounted muffler exhausted gasses through three large tail pipes located centrally between the twin rear undertray diffusers.

Honda S2000
Like other Type R, the all-alloy unit has hollow camshafts, FORGED pistons, con-rods as well as counter weight to reduce moment of inertia of moving parts. The VTEC is still a two-stage design, the second phase cut-in at about 5,000 rpm. Compression ratio of 11:1 is also unaltered. What separate it from other Type R powertrains are the bore / stroke aspect ratio and cam profile. Basically the 87mm bore is identical to Accord Type R’s, but the stroke is as much as 6.7mm shorter thus account for the reduced displacement. Measured at 87 x 84mm, we find it is obviously bias towards top end power and rev compare with Accord’s 87 x 90.7mm and Integra’s 81 x 87.2mm.
Honda Indy car
Pistons: Forged aluminum alloy
Ford SVT
The Cobra engine is built on a cast-iron block for strength. Other reinforcements include a forged-steel crankshaft, forged ¡°H-beam¡± connecting rods and FORGED pistons.
Viper
The engine's FORGED aluminum pistons are set in cast iron liners. The aluminum cylinder head features a conventional two valves per cylinder with higher-revving dual valve springs.
There are lots more out ther, Care to check, Lambos, Porsche, all other Ferraris?
