Neither want to pull into the 6,500 on up rpm much, both have or had large rollers and proper springs and such, current combo runs best shifted at 6,200. Nothing is the same on either motor besides the intake. I would have expected a much higher rpm.... at least 8000+ if the heads flow and the cam is big enough EDIT What do you call enough spring... whats the pressures W5 had 280 installed, 710 open, new motor has 340 installed, 820 open. Both are correct to coil bind also
