Budget 318 build

Oh! I missed a question so...

On flat top pistons, even the HP & race units are normally pretty far below the deck. Magnum blocks can be the exception due to a slightly shorter deck height. The manufacturers (should) list the piston height from the pin centerline.

High performance and racing pistons are normally taller but not tall enough to protrude above the blocks deck. This of course assumes a stock deck height.

The pistons are designed to be that way so the end user (you) & the machinist can furtherly machine the block (or not) to place the piston where it is needed to obtain the correct distance in the cylinder for the compression ratio you want/need. In conjunction with head gasket and cylinder head cc’s.

Performance and race pistons have valve reliefs (often for larger valves, this must be checked before ordering) that will help large cams.

Go to Summit racing’s web site and start clicking away on the left hand side bar until you find a suitable piston and read up on the specs.

Read through & make post on your selection and ask a few questions about what other people have done with there set up, with cam lift, general performance etc....
