360 Piston Help

[scottylack]

Bought a rebuilt motor with L2386 Speed Pro or Sealed Power federal Mogul pistons...

can someone give me some info on these pistons...like how much compression will they make with my 65 cc heads...?

thanks!!!

Try this calculator! You will need to know your bore/stroke etc,etc

Was just hoping someone had the stats on this particular piston ...anybody?

 

[scottylack]

anyone?

may have to look around the net some man. the info has to be out there . this is what i got on the summit site. not sure if thats the info you need or not. not sure if they are even the right piston. either way you'll have to do the math for your with your deck height,gasket and cc of the heads.

yea, I googled and googled ... seems like they are not made anymore ....

Call up Federal Mogul they probably still have the specs.

this link has the info you are looking for.....has compression height of pistons along with compression charts basis on head cc

 

[Mad Dart]

This is based on if block was not ZERO deck'd 65cc heads with .039 gaskets....... if it was Zero Deck'd the compression would be 10.363

3.58/2+6.123+1.591= 9.504 at TDC, Mopar Deck 9.60-9.504= .096 in the hole if the block was not square decked.

Without Zero Deck compression would be 8.484

Mad, keep in mind square decking is just to get the decks parallel to and equidistant from the crank centerline. The height could be any hieght really. I believe blueprint spec is 9.590 which is I think what you were getting at there.

Yes I understand...on the deck height I may be incorrect but thought it was 9.6 on Stock Deck height, I am sure there is room for variance though from Mother Mopar. I was giving the 2 heights so the OP would know to check it for himself and that any decking done on the block WILL affect the compression ratio.

I contacted Federal Mogul ... with my 65 cc heads and keeping the block and heads totally stock, standard gasket, 0.030 overbore, compression would be 8.98 ...

thanks to everyone that helped!
