Piston Liner Set 1300 74mm 1290cc Big Valve DISH DOME
[PL74-10.5]
$1,177.00 $995.00

MADE TO FIT 750-101 NORMAL AND VELOCE.  WITH NEW LINERS (FOR SS WITH MILLED BLOCK--INQUIRE.)

CUSTOM MADE TO FIT ALL 750-101 NORMAL/VELOCE/SS

CUSTOMER COMMENT:

I am working on my rebuild and admiring the quality of your overhaul kit.  The JE pistons are absolutely beautiful and I'd like to share the specs were spot on.  I couldn't measure any variation between them and they fit the liners perfectly to spec, .0003 being the largest variation I coukd find.  So happy for this.  EE, USA

The dish dome sides are reduced to allow clearance for all but the most severely milled heads. The valve reliefs are wide enough for the largest oversize valves and deep enough for almost any cam configuration.  

FEATURES:   

  • Tall shoulders of dome "squash" the mixture at TDC creating a hurricare to distribute the flames.
  • Deeper valve relief to accomodate most performance cams.
  • Larger diameter valve reliefs will accommodate oversize 40mm intake and 37mm exhaust valves.

COMPRESSION:  (Specify your choice in "Customer Comments" Box).

  • 10.5:1
  • 11.0:1 Special order
  • 11.5:2 Special order
  • 12.0:1 Special order

Compression is measured with standard head of 112mm height and 1.4mm Reinze gasket.  (Customer should submit actual head height and specify block milling on SS.)

THIS PISTON/LINER SET INCLUDES:

  • Standard pins (84 grams)
  • Conventional Ring Set
  • Wire locks.
  • New 74mm liners. 

UPGRADES:

YOU SHOULD CONSIDER THE FOLLOWING UPGRADES:  (Specify upgrades in "Customer Comments" box, when ordering online.) 

  • CARRILLO ROD SET of your choice, $50.00 off, if included with THIS order.
  • Light Pins (68g).  $80 Extra.
