he LRP ZR.32 Spec.4 Pullstart is based upon the very popular ZR.32. In order to be able to again increase the enormous power of the .32 monster, we build in a completely new constructed carburettor that has an additional notch for improved adjustability and that provides an even more efficient fuel-air mixture.

This leads besides an improved idle speed setting, also to better responsiveness and more torque. The already known Heavy-Duty CoolDown- Max cylinder head provides sufficient cooling for this power unit.

  • MASSIVE Big Block size - You cannot replace displacement with anything… but even more displacement!
  • New CoolDownMax cylinder head - Improved cooling and higher efficiency through new cooling fin arrangement

  • Standard burn room - Guarantees easy adjustment of the engine in all conditions

  • Massive con rod - Extra reinforced con rod. Specially adjusted for .32 engines
  • Ultra strong pullstart - Pullstart specifically developed for big block engines
  • Power Start capable - Prepared for the use of the LRP Power Start for starting the engine at the push of one button
