Guys we're proud to announce we have finalized the PRC 255 & 260cc LS3 aftermarket casting cylinder heads. These new runners are smaller than stock runners for improved velocity & move unmatched amounts of air! The 260cc runner moves right at 380cfm & the 255cc moves 370cfm!
255cc Heads Features:
260cc Heads Features:
Initial testing has shown the 255cc head to be capable of producing 600 flywheel horsepower through a stock intake LS3 engine on the TSP Superflow 902 engine dyno!
look for dyno data from strokers using the 260cc version very soon as we have several builds going together with them right now!

These are LS3 castings & move considerable more air than every major competitors cathedral head. If your looking for the ultimate LS cathedral head checkout the PRC 237 & 247 cylinder heads. I think you'll find they're the ultimate in LS cathedral technology.

Absolutely. With the smaller runner but big air should make great power. People have been putting ported LS3 heads on 408s for awhile, these should do pretty well considering they are moving more air then most ported stock LS3 casting but with a smaller runner still!
