I do remember in school i built a 400 hp sbc (at wheels) and teacher told us that the duel plane made about 25 or so more horses. We could choose single or duel plain. Every one chose the RACING single plain of chorse. Only one picked the duel and the made the most power. They also had the worst upgrades. We did heads and cam swap. Dont remember what cam but used prety stock vortec heads. I guess i will try the duel plain. I also found out my trans has corvette govener in it. Not sure what diff it makes but i think it shifts higer.
