Nope heads are the same as Cobra. Only difference is Cams and Intake and other very minor stuff.

 

So the same comparable year Mark/Cobra is going to have the same head?

 

Yes it will
and Teksid block. So when looking to build a bad *** 4V always look for a Mark VIII 4V in a salvage yard first can find them cheaper.

 

yeah i just purchased one myself, only difference is cams intake and newly found out not forged crank. everything else matches.

 

alright cause i got a 98mark that im tryng to up im tring to be different from evebodyelse who has mustang. i wanna put a 5 speed in it to

 

next ? is how can i get the mustang sound? cause i know when they started making the new style mustags they dont sound like them anymore. is it because they have the muffelers our back behind the rear instead of up front? it might be cause (headers)?

 

Get some weld in Flowmaster 40's

 

Ok, I know quite alot about both cars. Mark VIII has a 6 bolt flywheel, where a cobra has an 8 bolt flywheel. The cobra uses a forged crankshaft, the mark uses a non forged. The cams are slightly different, but not that much. All Mark VIII's use the swirl port B heads, the 96-98 cobra's do as well. 99+ Cobra's use the C heads. The C heads will bolt on the Mark VIII block. The cobra intake will work fine with the Mark VIII engine.

As far as accessories, the only thing that is non transferable on the Mark VIII from a GT mustang or 2v 4.6 is the alternator. Obviously the spark plug wires are different on the GT mustang, but not the Cobra.

That should be about everything.

 

so far i got 3.73 gears and exhuast next step is intake and the C-heads

 

my car has a 137,000 miles and if i overhaul it wat parts should i swap? bigger cams any differnt pistons, should i change my pitsons and go with bigger cam?
