yes you could..which we have talked about extensively in this forum....now the quesion is will 360 rods handle the HP....? and if your using 390 rods will the pistons handle the HP....I think the problem is noone has ventured down this road yet. To answer your question YES this height piston will work .....but will it hold the power you want...? that is a different question that depends on your build. and of course the rods.

Well, yes, technically you could...
The least deck clearance the 352 ever had stock (according to my book) was .030". So to get decent quench, you'd need a .010" thick head gasket. Even this piston is unavailable, as it was a one year 1960 352 4v piston. Most other 352 pistons gave .050" deck clearance, which combined with any available head gasket pretty much kills your compression and quench. With any of these combinations, you have to use long rods to keep the compression up and quench distance down. For a 3.5" stroke crank they'd probably hold up just fine. I suspect the extra piston speed of a longer stroke crank, combined with sustained 6000rpm usage, is where they get the bad reputation.
So yes, it'd be somewhat better than with 360 pistons, but it doesn't do anything spectacular.
I am planning a 3.5" stroke FE for running on alcohol, but that's in the planning stages, and I will be using custom pistons.
