Has anybody used Speed Pros hypereutectic pistons.
Part# 844-h535cp page 26 Jegs

They say CR of 9.14 with 92cc heads.

I'm getting ready to buy saome pistons soon, Heads D3VE-A2A 92cc

Any suggestions would be great to get the CR up.

You could deck the block .010 and help some. It probably wouldn't be a bad idea to true the top of the block to the crank. get your pistons hung and then put number one and four in and measure the deck height....then do number five and eight on the other side. If they aren't close to the same, then have the blopck trued to the crank and tell them to take another .010-.020" off.

 

Speed Pro has a set of domed forged pistons that will provide 10.5:1 c/r with 92cc heads. Jegs did list them in their catalog. If not, call them (or anyone else who carries Speed Pro) and they can order what you need. Delivery to me was three weeks.
