Peak HP from LA block w/ no problems

if it helps any, i had a heck of a time with cooling(210-220) and decided to spend the money and have one really DONE, but stock. i have a 22" radiator, 72 square tank, 3 row, hi-efficiency(tubes are 3/8" on center, not 1/2") and dimpled tubes. the dimpled tubes slow the water down and the longer the water is in the radiator, the more it gets cooled. i run on the highway and the city streets at 180* and maybe on a hot day in the valley in traffic i'll hit 190*.
