how would you invest 5k for more hp?

Buy your parts and the shop I use will hook you up cheaper than anyone else. He is in Bloomington and is certified mechanic that has built many motors. He owns a shop and just him and his father are the only people that work there. I have had them build two motors for me and never had a problem. They built a 4.6 DOHC for my Mach 1 and badass 340 for my Duster. If you want to be charged more, but still have a good motor built with your parts, Precision Engines in Bloomington built my uncles 97 Cobra
engine. He was like you and wouldn't listen to me and his motor cost him about 900 bucks more in labor. That is a trak-lok and stall converter in terms of parts. Find yourself a cheap Mark pos and part it out keep the motor strip it down to the block. Have the block bored 30 over and fill it with forged internals, get some nice heads and so on. Also, why are you against centrifugal superchargers. They are perfectly capable of making 700-800hp with a properly built motor. I have a Vortech V-2 in the for sale section for $1500. It alone add 134hp and 88ft.lb/tq to my bone stock Mach 1 until I had a motor built for it and got a Procharger.
 
after i talk with my local guys on monday I'll get ahold of you philly to see how to contact your guys and then figure out which way i lean towards.

the only problem i see with the whole teat it down and build it up is I dont know what the :q:q:q:q im doin.And my only other person I have to help me is uncle jimmy and i dont think he know wants to do it either.He just keeps pushing me to lean more towards a simple swap (for the obvious reasons).

therefore if i pay a shop to do all the tearing down and all the building up what will i have in it? also 94m5 says took him 2 10 hour shifts just to run all the wiring and all the connectors wouldnt work. that just sounds like a nightmare to me.
 
LSC8 wut headers did you use with the c heads that fit in the Mark, I'm thinking of getting a 99-02 continental engine with c heads and building that up does anyone know what the difference between the continental heads and the cobra mach1 and marauder heads is, is it just the cams cause the all make way more power than the continentals

B heads share the same exauhst patter as c heads. Continental heads will work as well, but not the block.
 
Ok thats wut I figured well even if you cant use the block you can get an engine out of one for as cheap as a mark engine but do you know if you could get the same amount of power out of those heads

Well kinda. There are a few different "C" heads. The 99/01 Cobra and last gen Contis all have the same head. The 03/04 and Mach have an improved design on the runners to help accelerate the air. Its only a 1 or 2 hp difference though so no big deal. The FR500 heads are also "C" heads but have an even better port. They are really great to squeeze the most out of a NA motor.

Thanks for the header info though Mike! For some reason I thought the exhaust ports were different between the "B" and "C" heads.

Also, for some reason the "C" head is more prone to ticking versus the "B" heads so doing the cooling mod is very important on a "C" head conversion that is gonna be blown. Need to run a x-over tube from the back of the head on the drivers side to the passenger side. That allows the cooling for #7&8 to work better. The cooling mod is about $120 though.
I would like to do it on my motor but since I have spent all my money for the engine swap I am gonna see if I can engineer one using the cooling port off the old motor and making it work on the drivers side for the new motor. :)
 
C-Heads are 99-01, terminator heads are 03-04 cobra. Machs and marauders got the earlier design. The difference between them is the exaust port is different.

Then you have the cobra R 5.4 heads, fr500 etc etc etc.
 
Wait, now that I think about it, my marauder engine has the blue stripe revised head already. So the machs/marauders should have the terminator heads as well.

They do and they are "C" heads. SVO has this incredible book that breaks down all the modular motors, flow rates and design changes from year to year. It shows a cross section of the various "C" heads port changes. The differences are just slight internal angle changes of the ports and prolly wouldn't notice it with the nekkid eye.

Also the blue stripe thing is widely misinterpreted. The old "story" was that on Cobras if it has the blue paint then its the revised design and wont get the head tick. I believed that when I bought both my 03 Cobras thinking they had the updated head. Turns out thats untrue and the blue paint just means it was inspected. Since then I have confirmed that with a couple friends box stock 03 Cobras by locating the blue paint on the heads.

In the Mustang world there are 100's of different wives tales as to what head is what. Thing is late production 04 heads can still get the tick too. Really needs the head cooling mod.
My friend John had a last month production 04 Cobra and went through three drivers side heads under warranty as they all developed the tick.

Anyway, all Mach1's, Terminator Cobras and late production Marauders have the same head revision on them.

I have been trying to figure out what the Aviators have in them though. Not sure if its the newer design or what.

Meh, one day I may do a "C" head swap and will prolly just get the cheaper earlier version. :)
 
ahhh how i learn so much just reading others conversations!

With a good TC and a trans cooler then the trans will do a good job of holding up. If you upgrade to a 98 trans with those mods then you can handle it no problem. I know at least 20 people with mustangs and the auto running 450ish rwhp and have no problems with them and all the trans mods they have are coolers and TC and J-mods.
------------------------------------------------------------------------------------------ I have seen a couple times in here to use a 98 trans and I previously read that you want a 1997 or newer. Heck I bought a 97 just for the trans (plus Kooks headers) we converted it to a 1993 DD valve body. It was for my supercharged 1993 Mark. Works great but now you have me worried about future problems.

At that power level you still have to know how to drive them (i.e. not causing the trans to downshift from 4th to 2nd). You really end up using the OD button more to have the unit behave like a manual in the 4th and 3rd gear areas.
 
So does that cooling mod prevent the ticking problem and wut in the head is actually going bad and ticking
 
yeah i got a "ticking" right now in mine. but it is constant not just start up.
you dont hear it at all on the outside or in the engine compartment but inside you do. speedometer cable?
 
Philly, you are wrong.

The cooling mod for c heads, is to keep 7-8 cool. Without it, that area of the head tends to burn out the valve guides, and seals. It's more common on supercharged c head applications.

The timing chain rattle is a seperate issue.

The cooling mod greatly increases the chances of NOT getting it but people still figure out new and ingenious ways to overheat these motors and kill them anyway.

The tick you guys are hearing is more then likely timing chain slap. The head tick is just that, sounds like a loud wrist watch, its an actual tick. What causes it is the head heating up and deforming a little causeing contact with a couple valves and guides.

Not something you typically see on a Mark and is usually reserved for blown cars.


EDIT: Dan Halen beat me to it! :lol:
 
The cooling mod has been much over played and came about with the non-intercooled superchargers. You can buy the kits from some well known tuners if you feel the need to have one.
 
Mine ticks when I start it up for about 5 seconds and was told all mod motors do this. Due to not having enough oil pressure (or flow) up to the heads on cold start-up. Dirt, a little rough machining in the adjuster or low oil pressure/flow can certainly affect valve-noise in these heads.

Here is what I read on another forum back when I had my Mach. Sorry I was wrong.

The lead engineer of SVT (can't recall his name) was at one of our on-track events in College Station three years ago. Anyway, he explained that in the oil channel as it passed two of the valves (can't recall whether intake or exhaust) there was a little "diverter" cast in just btwn the valves (like a sandbar sticking straight out into a river). On the down channel side of the diverter, turbulance was created , oil remainded there and super heated that valve causing it to warp and that caused the ticking.

I have two superchaged 4.6's, a 93 Mark non intercooled 7 PSI and a 03 Cobra 14 PSI. From what I've read I should look into this. Where would I look.
