I've read a few articles about the benefits of 96-98 cobra cams or even 99-01 cobra cams in the later 4V heads found on the 03/04 cobra, Mach, Marauder, and Lincoln Aviator.
I have a 99 cobra with a procharger and an Aviator long block that has the later 4V heads and cams. (The same long block found on the Mach 1's)
But I'm thinking of doing a "budget" cam swap and trying to find a set of 96-98 cobra cams.
From what I understand, these cams are geared a little more towards the higher RPM, but can unleash some extra potential in these later 4V heads.
Has anyone done this swap? What advantages do they offer, if any? I'd be happy with an extra 15-20 HP. But I don't want to trade off the low end torque that the 03/04 heads and cams offer. It's a HUGE difference compared to my combination with the 99-01 cobra heads.
If these cams don't really provide much of a benefit for the cost and work necessary for the swap, what do you think the best 4V FACTORY cams for the 03/04 4V heads? I know the FGT or 00 cobra cams would be the best, but given their availability, let's assume they don't exist.
What's the difference in the Navigator cams? Are they basically the same thing as the 06-98 cams or 99-01 cams? Or were they designed for better breathing on the 5.4?
This sounds crazy, but what about the 4V "intech" cams in the front wheel drive Lincoln Continental?
