Say I found a complete mark8 motor fairly cheap, and perhapse found some 04 mach 1 heads, also fairly cheap. Aside from the intake manifold, is there anything different? Will it all bolt up just the same?

Yes you can mix and match modular stuff. I have 01 lincoln navigator heads (5.4 4v) on a teksid block with my Mach intake.

are the navi heads B heads to??

 

[DickH]

Well I was mostly worried about things like the timing chains/cover and whatnot. Is it a direct swap, or are there little things here and there that need changed as well.

Really? I thought the Navi heads were too much for an N/A 4.6L.

 

[SWEET2KSTANG]

well, the original plan got out of budget. those heads will be utilized soon enough

 

[SWEET2KSTANG]

as far as mixing and matchin, it can all be done. the 4v stuff is all interchangable with the exception of b-head or c-head set up. all the components like bearings, bolts, chains, tensioners, etc are all the same.

 

[Boostang]

you can put a cobra intake on the b-heads tho right!?

 

[98Cobra_sleeper]

yeah B heads are cobra heads, just the 96-98 cobra

where do u shift at? what hp does ur car come with stock?

Who is this directed towards?

For b-port cars, stock at the crank is 3[email protected], [email protected], and I've heard that you shift absolutely as late as possible that won't hit the rev limiter (so, 6500? 6700?).

I don't drag race, though, so I'd wait 'til someone else chimed in on a proper shift point.

 

[Boostang]

what are the hp/tq numbers with the 99-01 cobra's (c-heads)..?

 

[DickH]

Well that's all good news, I wanted a 4v for cheap. Now I'm seriously thinking about picking up the motor and throwing in a forged rotating assembly, then get some 04 3v heads on it and call it a day. Is there anything more to it?

 

[Boostang]

i dunno if the pi intake willl fit on the 3v heads.. but if not i know the throttle on the 3v's arn't cable driven.. but there is a converstion kit for this tho

well i've never had my car in stock form, so i dont know. i always shifted like at 6500 in case i didn't shift fast so i didn't overrev.

I'm assuming you mean 04 4v heads right? there aren't 04 3v heads.

 

[Boostang]

^^^ lol i didnt catch that!! dang!!

 

[ReverendDexter]

what are the hp/tq numbers with the 99-01 cobra's (c-heads)..?

The Cobras were supposedly overrated at 315 or 320hp, the Mach 1s were supposedly underrated at 310-315hp.

 

[Boostang]

ooh... i so theres not a big difference between the 98 and 01 cobras?

 

[DickH]

I'm assuming you mean 04 4v heads right? there aren't 04 3v heads.

yep yep, was thinking 03/04 4v, and did not type it.

Hm... what else is there to a motor besides the rotating assembly, block, heads, chain, chain cover, and oil/water pumps? If im swapping heads/internals, would it be cheaper to just buy everything and build the motor, or is there a lot of little **** that adds up?
