The first is a 32V 5.4...............the second is a a 5.4 with 4.6 cobra 4 valve heads...........and the last is a 2000L motor in need of a rebuild.
One of these lucky recipients will be topped off with a whipple charger and a NX wet sysytem. Housed below will be forged rods CP pistons .020 over, billet cams activating 1mm over stainless valves and of course a few secrets.

hmmm, I vote for the navi motor build it up strong and blow the **** out of it

 

me TOO!!!!

Why not a Kenne Bell unit though..........is that possible???

JC

 

Supercharger will be a Kenne Bell whipple charger

 

AHHHHHHHHHHHHH

We think alike my good orange friend!!!



JC

 

OOOH yeah, how's that for blown

 

I vote for the 5.4 with the Cobra heads, they flow a lot better.

 

How about this, build all 3 motors. When your done the one you like the best keep, the second best you can give to me, and the 3rd you can sell

I honestly have to do some comparative work between the cobra 4V heads and the Nav 4V heads to get some actual flow data. I want to measure the intake and exhaust port volume, chamber cc and actual flow based on particular valve lift numbers.. Although flow and volume are the most important I can tell you visually the cobra heads intake ports are much narrower..

Captain
there you go using those dirty( " give") four letter words again...lol... but in the event my money tree grows which one would you prefer...

 

I'm kinda partial to the Navy engine, though a Cobra R engine with Novi on it would work just as well. And if money wasn't an issue I'd say a S/C V-10 from the superduties

so I say the navigator engine
