New MMR Big Bore Stroker 5.3L 324ci in Cali!

[dohc324ci]

Hey all finally bit the bullet and put a deposit down to lock in my pricing for a MMR Big Bore Stroker 850 9.5:1cr w/ FRPP Boss 302 (5.3L w/stroker):banana2:
Rick over at MMR has been great to work with.

Re using my heads MMR P&P Stage III valve job w/03/04 Cobra SC cams (take offs) There are no smog legal cams even ones that will pass for California! Will research but doubt it.

:beer:

[FordNut]

Pretty sure the Marauder cams are the same as the '03-'04 Cobra cams.

[dohc324ci]

FordNut,

You have stock MM cams?

[CBT]

No picture of it?

[FordNut]

FordNut,

No, mine are custom grinds from Comp Cams. For sure not smog legal.

[dohc324ci]

No, I'll def. post when the motor is in. 6-8 weeks.

[ImpalaSlayer]

very nice man! im jelous

I remember Lidio saying the same thing....

[Joe Walsh]

Would the FORD GT cams be smog legal?
I would think that they would....they sold FORD GTs in California.

That will be a killer engine combo.
3.70" bore iron block with a 3.75" forged stroker crank. :bows:

[dohc324ci]

They'll cost me 100.00 bucks. There new take offs. I have 115k on mine dont know if I need to replace.....

Yeah...let me check on that I did see a FR500 cam option for this motor on there website.. When speaking with them they steered me away from it because their Comp setup netted more HP.

[babbage]

sounds very nice. Are they going to give you a dyno sheet with it? What do you think it will make HP wise? 450 at the crank?

I am having it tuned then dynoed. Yes hoping to get 360-
380rwhp..:banana2:

[jdenning002]

I can't wait to check it out...

That's realistic.

Absolutely correct, also the exact same cams on Mach I.

[dohc324ci]

I guess the thinking is since I am reusing my heads and having them ported and polished...why not install a fresh set of CAMS (MMR has new Cobra take offs for $100) since I have 115k on my existing set now.

I need to pass smog (California) so keeping the stock cams would be the way to go.

I thought MMR send a dyno graph to the customer with every engine.
That's what they do? They use an engine dyno, so it should be around 4xx..

Dunno....I'll check with Rick over at MMR.

I forget, what's wrong with the current engine?
If it's running, you'll have less down time and probably come out better in the long run by purchasing a set of heads (like I'm trying to sell) and having them ported etc, then put them on the new enine. Then sell your old engine intact and you will come out better financially than pulling your engine apart to use the heads off of it.

How much for your heads? What condition, etc...

Believe me I thought about that.

But having a built engine with heads is an additional 2.5-3k ported. How much are you selling your set for?

Whats the going price for a full 03 Marauder longblock with a rod knock going for?

[dohc324ci]

Down to a couple choices for Cams. Duration under 218 which I hear is the magic number when passing smog hear in Cali.
OEM 185-195
FR500 Cams 214-204
Ford GT Cams 197-197
Crower Stage II NA 210-216

[dohc324ci]

Update.

I have decided to go with 10:1 compression vs 9.5:1. Based on my conversation with the engine builder and tuner I can still safety run boost at 8-10lbs w/ 91oct; 12-14lbs w/93 oct. Also, I decided to go with Ford GT Cams vs after market close to OEM duration which will pass smog in Cali. This according to the builder should do 460-475rwhp!

475 N/A with 10:1 comp and just ford GT cams... I'm gonna go ahead and :bs: nothing against the builder but that's a little unreal, unless that's on boost

Wow! Is that projected 475 rwhp N/A through an automatic trans?! Are you spinning the motor to 8500+ rpm? You will need lots more cam than GT cams.

Those numbers at the wheels are what 2010 GT500 are putting down with 5.4 DOHC Supercharged with manual trans.

Props to you builder if your car can put down those numbers N/A, but I think it will cost you a lot more (lots more) than you think.

[dohc324ci]

I was thinking about that as well; we shall see. If not there is always the power adder!

I am hoping with the 10.5 compression, stroker kit, the stage III ported heads, Ford GT Cams and Iron big bore will get me to 400rwhp. But looking at the list in the links its at least a possibility.

Also, I believe that the 5.4L 4v is running low compression 8.5:1 for boost.

so he was saying 475whp N/A?

[dohc324ci]

Yeah, I was talking to Rick over at MMR on the final combo with the Ford GT Cams and what it would ultimately produce and he said "460-475hp" I assumed at the crank. We keep talking about other stuff "his Plum Crazy Dodge Charger" my wife not wanting to hear about my Big Bore Stroker combo anymore. I had to circle back and clarify so I said so those numbers are the flywheel/crank right? no at the wheels:eek:

So I wont know until the motor is installed, properly broken in and tuned:coolman:

[dohc324ci]

Dont blame that logic.

Just to clarify:

FRPP Boss Iron Block Big Bore, MMR forged Stroker crankshaft 3.750 to get 5.3L, MMR Stage III Ported Heads, 10:1 compression and Ford GT Cams.:burnout: 400+rwhp is my target. Anything more is gravy.

Similar setup but w/o stroker:

I hope it makes power like that man, that would be sexy, I'd pull my heads off for them to port the next day :lol:

Ok I really hate this board:mad: I am now looking at the ported short intake runner from Natzy:bigcry: With the BB Stroker, Heads, and Cams might as well do the intake what a couple of hundred dollars? Actually by going with the Ford GT Cams $420 I can now spring for the Ported Intake I am still within my project budget:beer:

Scratch that. My Ford GT Cams and that NAZ PSR Intake wont match up well....I am putting dollars toward the fuel system GT-40 Pump and Cobra Fuel 39lb Injectors.

How much power did you say you plan on making?

[dohc324ci]

Based on my combo (see sig) I am hoping 400rwhp/380rwtq..or abouts. I was on other forums and others with similar combo making around that on 91 octane.

[FordNut]

I'd guess 360-380

[dohc324ci]

I'd guess 360-380

I think your right; alot of the guys at 400rwhp had ported intakes; headers....as well. But I am still hoping:depress:

[FordNut]

Just going from experience. Mine was 5.3 NA, Comp Cams, ported heads, oversize valves, Kooks, ported intake (not short runner), 9.5:1 cr. Keep in mind most of the 'stang numbers are with a manual transmission.

FordNut you are such a killjoy:lol:

I guess DR Vortech at 12lbs should satisfy the hunger for mo poowa!

[FordNut]

I was hoping for 400 NA, too.
With a build like that, a Vortech at 10 will make plenty of safe power and be easier on the whole engine.

[dohc324ci]

Hey Joe how much rwhp are you putting down?
