351W pistons

[StangNut86]

time to get picky.

i need a set of pistons. they need to make 10.5:1 with 61cc chambers. bore 4.03, stroke 4, rod 6.25, pin .927. that's about it. any suggestions as to brand, or even specific links? thanks =)

As far as I know, nobody makes a shelf stock piston exactly what you want. Any of the piston manufacturers will make you a custom piston though, you want a 17CC dish assuming a .045" deck height with a 61CC chamber to give you 10.5:1 compression.

i think trick flow may have what your looking for, it may have just been 10:1 that i saw though.

Trick flow pistons are for a 6.2" rod and have twisted wedge valve reliefs, so I don't think they would work with a normal head, nor with a 6.25" rod.

i'm actually still flexible on my rod length and such. and i'm using the trick flow twisted wedge type r heads, so those pistons wouldn't be a problem. thing is, they just don't make the compression... it's either too much or too little. but, i'm getting with the guys at Probe to have some custom pistons machined sometime in the future. i'm not set on brand either, but i've heard some convincing arguments for those guys.

now, here's a stupid question: what exactly is compression height, and deck height? clearly, i still have a lot of research to do =)

thanks again

keith black. very lightweight = more power.
about 200 bucks.

If you're going to have a custom set of pistons made I highly recommend CP pistons. Very light, VERY exact tolerances, and great customer service.

Compression height is the distance from the top of the piston to the first compression ring, deck height can mean either the distance from the crank centerline to the top of the bore on the block, or the distance from the top of the piston at TDC to the bottom of the cylinder head, including the headgasket, while torqued down.
