hey all, I have a 1988 Z25 with a crate 468 dynoed at 440HP. Have a 19p prop on it now and runs 5500rpm at WOT. Haven't GPSed it yet. Any ideas on what pitch I should be running ?

a 25p 3 blade will put you at 4900 rpms,,i would shoot for a Revolution 4 24p tho..

so your saying that 4900 rpm is what I'm supposed to run at wot ?
You may be hitting the limiter if that pack has one! Borrow a steeper pitch before plunking down dollars.
