The peak HP was @ 4200 RPM just as a stock 200 would have peaked at that RPM too! Remember this 200 Block is Stock even the Cam!

Does your distributor have mechanical advance or is it the old vacuum only unit. If it's the vacuum only, there are at least 5 more horses hidden there by switching to a later dizzy..
