Back in the early 70's Chevy launched the New Vega with its 2.3L all aluminium block and iron head.
Reynolds Metal Co. developed a eutectic aluminum alloy called A-390, composed of 77 percent aluminum, 17 percent silicon, 4 percent copper, 1 percent iron, and traces of phosphorus, zinc, manganese, and titanium.
I guess I don't have to tell some of you older guys how that turned out for GM.
Back in the mid 60's we sold Bridgestone motorcycles and their motors used aluminium bores with industrial hard chrome plating. It worked okay, but there were no options for re-boring or honing the bore when replacing pistons.
I hope the new 131" system has the bugs worked out of it.
At the risk of dating myself, I won a “non running” Vega GT in a poker game.
Since it was scheduled to rain over the weekend, I went and bout a resleeved steel lined motor from a Machine shop on a Friday at lunch, went home and over the weekend pulled to old worn out one, put in the new one and put the core in the hatch to be returned Monday for the core deposit refund. It gave me great service as a commuter car for several years until I sold it.
