built by Power Source Distributor in Miami(30 years of experience) and also Dyno tuned by Mesa Balancing Racing ( Laz Mesa).Engines are very conservative, and were built looking for reliability. I did not want to push them for more HP, Note that the 400hp are obtain at 5200 rpm and the peak torque of 460 lb/tq at 3000 rpm and maintaining it further up in the power band.
