MMX is Proud to announce our NEW 2618 High Compression 11.5CC Dome Drop in Piston and Rod Kit! This new piston is designed with the N/A, Nitrous, or Boosted customer who wants to run a higher compression ratio than stock. We have added an oil support rail on this piston set, to allow for a maxed out fireland (ring down) distance. The top ring is down .325 on this piston. This new piston is rated for up to a 350 shot of nitrous, and will handle just as much power as our lower compression 2618 drop in piston. STD and +.010 overbore are offered. 

Compression Ratio's are As follows:
  • 73CC Stock 6.4 Head: 
  • .027 Cometic Gasket 12.44:1
  • .037 Stock 6.4 Gasket 12.1:1
  • .040 Cometic Gasket  11.98:1
  • .054 Cometic Gasket 11.58:1 

67cc Edelbrock Head:
  • .027 Cometic Gasket 13.52:1
  • .037 Stock 6.4 Gasket 13.10:1
  • .040 Cometic Gasket 12.96:1
  • .054 Cometic Gasket  12.43:1

65CC 5.7 Eagle Head:
  • .027 Cometic Gasket 13.92:1
  • .037 Stock 6.4 Gasket 13.48:1
  • .040 Cometic Gasket 13.33:1
  • .054 Cometic Gasket 12.77:1

BE SURE TO CONSULT YOUR TUNER OR ENGINE BUILDER TO DISCUSS COMPRESSION RATIO OPTIONS THAT ARE RIGHT FOR YOUR BUILD. THE ONLY COMBO MMX WOULD RECOMMEND FOR 93 OCTANE PUMP GAS IS THE STOCK 6.4 HEAD WITH .054 COMETIC HEAD GASKET FOR 11.5:1 

Our Drop-In Piston Package is capable of supporting 1000 RWHP, but some of our customers have seen numbers up to 1300 RWHP with supporting modifications.

No engine build delays - No balancing charges - Less down time - No engine shipping cost
