Well my point was is that your original flexplate failed after almost 50 years. That's good service life. If you don't constantly abuse or drag race your car, a stock replacement will probably last another 50 years. Install what ever you want.
Yeah, duuuhhh. I missed that point. You're right. It has been nearly 50 years. How much hp is an original flexplate good for? The most I would imagine I will ever have is … ummmmm, maybe 450-500 at the crank. Right now it is probably at ~325 hp at the crank (270 at the tires).
