Set of Sealed Power hypereutevtic pistons

Perfect for an economic stocker type rebuild. Sealed Power hypereutectic pistons,. 030 over bore, 455. installed on stock rods. Rods were honed.New never used. $225.+shipping.

 

If these are for a 430 I would be the next in line.

 

These are for a 455. Compression is like a 71 455 with the dish in it,and stock everything else..but it still depends on if block was decked, heads milled and gasket thickness. You could establish whatever cr you want using those parameters.

 

Nobody doing an economical build?

 

So without decking or machining heads, around 8.5:1?

 

What year block and heads?

 

1973 block and heads

 

Based on typical properties of the head cc and deck height you'd be about 9 to 1 with a ,040" gasket. If the heads are off, mill them flat anyway to assure a good gasket seal.If you take .010 you'll increase compression to 9.2 to 1 then use a .027" gasket and you'll gain again to 9.6 to 1.

 

I truly appreciate you doing the calculations but I think I will pass. I want to be at least 10:1 and not have to spend a lot on machining deck or heads.

 

Yeah,you'll need to get some pistons with less than 15cc in the dish then.

 

TTT
