HPR 468. One of our signature engines is the 468 cid LS. The Erik Koenig designed piston, rod, and crank combo make this unique in that everything fits inside of a standard deck height LS block (iron or aluminum) so fitment in almost any chassis does not require any special engine mounts or exhaust. Serial number 001 will be making its way into a local road race car, stay tuned for updates!
