Looks like I'll be pulling the #'s 440 out of my 71 GTX for a potential rebuild. I was wondering what we be the best piston choice to move to a flat top. I was considering the KB version. But was also considering the FM2355 sixpack piston. Thought its a heavy [censored], but same gram weight as current stock piston.

Need I say that its a budget shortblock build...

Thanks
Chris
