Redline stock is between 6250 and 6800 rpm.

I know my 5.0, which is an '84, so it's carburated, is horribly under-carbed at 480 cfm... It run's out of breath by 5k. Nowhere near enough air with the stock carb.

Once you look at the EFI cars (1986-1993), even with the 55mm MAF, they flow 550 cfm. Upgrade the intake, heads and exhaust, and a well tuned 5.0 can take over 800 cfm.

Perhaps they should have got their numbers right. I call B.S. :thumbsdownsmileyanim:
