Depends in the comb, each and every time. Today, I would t even think about a single plane unless the cam was at least 255@050 in a light car. Have it ported and run it to 7K. It’s a big plenum/short runner intake.
I sorta agree the airgap is they way to go for from idle to 5k perfect street intake good street/strip setup
I always liked single planes if using a stall id run one still
the fact the torker made more hp then the holly grade strip dom is funny
It was said with spray run a single plane better distribution but engine masters proved that wrong
open plenum intake use a 4 hole spacer made better power then open engine masters
dual plane use and open spacer made more power then 4 hole engine masters
spray on dual plane open spacer should be the ticket.
But sometimes if running a stroker or spray or both you can could afford to give away some low end might help hook
combo dependent
