well now i have been trying to get a straight da-- answer on why evryone is so down on the 95 and earlier stuff over on tccoa johnny and i get an answer here . all the plans and ideas i have for mine are on the back burner till the 53 gets done now , but i'm enjoying beating the hades outta the bird , and honestly the oe 4.6 in it is just fine for daily use . i got a later , 98-99 , 4.6 out of a crown vic squad i picked up so when it's time i geuss i'll turn my attention to it ! the only mods i've done so far are the xmas present duals with flowmasters , it already had a chip / tuner { don't remember who's as it's been a while since i removed the kick panel and looked in there } as there is no speed limiter , and peicing together a cold air kit using the stock air box and a k&n filter , just gotta find a replacement for that dain violin case on the engine ! it can take care of itself , but it's no rocketship .

 

How do you like the flow masters? I am thinking of doing that to mine.

 

yep

New idea, what about cobra heads on the 2v explorer block?

 

That would work,but your compression will be a bit low due to the large dish in the pistons on the Explorer shortblock.

How much of an issue is that?

I am having trouble finding the 02- explorer moter.
How much HP do you think I would lose with a 96 CV block and cobra heads Vs the explorer motor with cobra heads?

 

Well, the PI shortblock pistons have ~18cc if memory serves me well, NPI shortblocks have pistons with ~10cc dish,and the 4V N/A engines have pistons with ~2.8cc dish.
car-part.com lists a few different engines available in the Dallas area for around $900. 2002-2004 are all the same.

I do not have a lot of cash to put into this, if it comes down to it, what would you spend the money on, the Explorer motor with 2v heads or the 96 and a set of cobra heads and pistons?

A guy I know only wants $200 bucks for the cv motor, and I cant find the explorer motor cheaper than the ones you found.

 

It all depends on how you wanna go about it.
Here's, IMO-the best "bang for the buck"

Find a '93-'98 Lincoln Mark VIII shortblock.
Get a set of '97-'99 NPI heads.
Get a set of PI cams
Get a PI intake manifold(Mustang,CV,etc).
You can do the same thing with a complete '96 engine and a set of pistons and/or rods from a '93-'98 Mark VIII / '96-'01 Cobra,but you'll be 84 lbs heavier with the iron block.

This setup will net approx 250rwhp,and will get that CV into the mid-low 14's. FAR quicker than stock,and with the right gear and converter selection,it might dip into the 13's. You're gonna have to have a custom tune done to account for the 10.2:1 CR that those small dish pistons make with the NPI heads, but the power is really good,with a fat torque curve and a nice power peak. Some people get all hung up on unrealistic numbers, when the fact is that a low 14 second to high 13 second car is really a quick street car-much quicker than most out there.

I have a set sitting on the shelf.


And that can come off of any 2V 4.6 made MY 2000 and later, right?



I have a tuner from 5 star, I can talk to Mike about re-tuning it for the new motor.

If I could run a 14.5 I would be vary happy.

It would run super unleaded only after this, right?

Would this really put out as much HP as 4V heads would?

If you allow 30% loss in the tranny and rear diff., thats 325 at the flywheel with 2v heads.

 

There's nowhere near 30% loss-18% is a realistic number.
Premium fuel would be best-but you could run 87 if you'd like-you'd just be down on power a bit.
2000 and later vehicles should all have the PI intake,some 2000 model cars did not though,so be careful if you're looking for one.
JL

 

Ok, I have read 15% for a stick and 30% with an auto.


So how can this 2V setup make ( close to, at least) the same power as 4V, DOHC heads?

That is the one thing I do not get, do the 4V heads not flow very well or can the engine just not make use of all the extra flow?

 

JL, have you ever heard anything about Hitech motorsports stg 2 cams?

I found some brand new for a great price.

 

Cams are a bit of a crapshoot on a modular. Not many companies know enough about or understand the valvetrain on these engines.
I've heard of good results with those, but not sure on what they'd do on your application. My suggestion is to speak with Nick at modularheadshop.com
He's dealt with those cams before and can give you some real world input/results.
JL

 

They will allow the powerband to move up if the heads and cams allow it, but they don't give up any low-end and start to seriously over-power stock or ported PIs by the 3500-4000 rpm range.

It is a twisted wedge chamber with a rotated valve arrangement, unshrouding the intake valve allowing better flow across the board, even at low and mid lifts.

 

HiTech cams outperform Nick's cams, which Nick does not spec himself. Brian Ebert is one of the sharper cam grinders/head porters out there.

HiTech uses Comp for their grinds, Nick uses Bullet Cams.
