Thoughts on MMR Short block?

SUHLeen · February 2nd, 2009, 09:32 AM

So still doing some research and talking to a few different people about short blocks and a few people keep telling me about MMR. I checked them out and they seem to have some pretty good prices. Did some more looking around and pieced together an engine build from them to do in my car. Let me know what you guys think about this set up:

MMR 2005-2010 Mustang Annihilator 5.0 950 STROKER Shortblock

This STROKER shortblock adds .4 liters to your 2005-2010 Mustang engine without anyone knowing, all factory parts bolt right on! Designed specifically for the 2005-2010 Mustang, great for blowers, turbo or Nitrous. With no other changes this Stroker shortblock will add up to 40HP and 40ft lbs of torque! This shortblock can support up to 900 Rear wheel horsepower!!

Features include:
*Brand New Cast Iron 2004 Cobra Block, torque plate bored and honed

*New 4340 Forged 3.750 stroke Crankshaft w/micro polished journals

*New 4340 Forged H-beam Rods w/ ARP BOLTS

*Speed Pro/Federal Mogul Race series Rod and Main bearings

*Speed Pro file fit rings 1.5mm Top, 1.5mm Second, 3mm Oil ring(precision file fit to your application, nitrous, blower, turbo or N/A)

*Complete Pro Assembly, blueprinted and digitally Balanced for the smoothest, highest revving shortblock available for your 05'.

MMR Proudly uses the following manufacturers in ALL engines!

Options:

MMR 2005-2010 7Qrt Oil pan, Red, Black or Silver $229.99 (save $20)

MMR 2005-2010 oil pan windage Tray +10HP! $129.99

MMR 2005-2010 3v Street/race oil Pump (highly recommended) $269.99

ARP Main Stud Kit (recommended for 600+HP) $169.99

Plug and dowel Kit (required when switching from aluminum Block) $69.99

MMR/Felpro 05-10 Head Gaskets (used in our 1500 HP racecar) $169.99

The only option I wouldn't do is getting the block alum. (unless there is a good reason(s) to do alum...?)

Also, I'd like to get their stage 3 heads:

MMR Stage 3 Ported 3V RACING Cylinder heads (2005-2010)

MMR Stage 3 ported and polished cylinder heads feature 306/222 CFM Ports, gain 45-50 More HP on stock applications and up to 80 more HP on Forced induction applications. These heads utilize fully ported and polished intake and exhaust ports, with Manley Nextec Polished Racing Valve springs. Heads include Racing Stainless Steel Valves 35mm intake & 38.5mm exhaust, multi axis competition valve job, fully assembled (no cams) No core required! NO CORE CHARGE! MMR guarantees more power than the competition or your money back!

THIS IS THE BADDEST 3V CYLINDER HEAD ON THE MARKET TODAY!

All MMR heads flowed @28 inches and .550 lift

You can find info on the block/parts here: Rear Seat Delete Kits

All that + their electric water pump, breather kit, alum. radiator, and motor mounts will run me just a little below $8k. The engine will be paired with my Kenne Bell 2.4L or possibly an upgrade to a KB 2.8H. (Most likely I will keep my 2.4 and do some cooling mods on it)

What do you guys think? Any of the options on the short block that I don't need? Opinions? I finally found who I want to do my install so it's just choosing the short block. Hoping to have this ordered and received by the end of Feb.

Why not Livernois?

New - Livernois Motorsports - 4.6L 3-Valve Modular Assembled Shortblock

SUHLeen · February 2nd, 2009, 10:38 AM

I like Livernois and they were my original choice but due to budget I changed my plans up a little.

After I talked with a local guy that is doing the engine swap and tune and what not, he made me realize a few things... I eventually wanted to do a fully built long block; a built/forged/stroked short block + stage 2 or stage 3 heads. At first I was going to use the stock heads for the time being and upgrade later so I could do more complimenting upgrades for all the extra power. It never occurred to me that I would need to buy bolts and gaskets and what not for the short block which would be anywhere in the $xxx range. If I do heads after I do the short block swap, I'd have to buy bolts and gaskets all over again thus wasting money.

So I'm basically looking for a solid long block, run low boost, and do other non-engine related mods in the future.

I had a long night last night and only a few hours of sleep so excuse me if I sound stupid/confusing lol

No you make perferct sense and thats 100% right about just costing more in the long run. Well let me know if the livernois your pick i can do something for you there.

SUHLeen · February 2nd, 2009, 11:05 AM

Replied to your pm!

Anyone else on thoughts of MMR? Good, bad, worth it?

Emay · February 2nd, 2009, 11:10 AM

I'd stay livernois if possible. If you do some research over on modular and SVT performance, there is plenty of banter about poor customer service, long waits on orders, and lack of care in catastrophic failures.

Emay · February 2nd, 2009, 11:16 AM

On a side note, have you looked into DSS short or longs? They have a long standing relationship with several guys running competetively in NMRA..

forensicsteve · February 2nd, 2009, 11:21 AM

Have the 5L MMR stroker. It's held up well under quite a bit of track abuse. I have no issues with MMR. Ordered pistons from them recently, took about 3 weeks over the holiday period...so not bad at all. At the same time, have shifted to Livernois for recent mods likes heads/cams and bunch of other stuff.

So far I have heard nothing but good things about Mark and the people at MMR. I tried doing some searching (not that much but some) and haven't heard anything bad. Have any posts in mind you can show me?

I looked at DSS a little, not much but a little. I will have to do some more research on them though

Why did you shift to Livernois? Is it an ongoing shift I.E. if you buy another block in the future it will be from them? Or did you just like certain things they offer?

07stanggt · February 2nd, 2009, 11:45 AM

Here is a thought for you.

MMR to my knowledge is not a machine shop, they are not buidling anything themselves in that sense, they buy the parts and assemble it, send anything that needs machined out probably to the lowest bidder, how else do they get the lowest price? I could be wrong, but im pretty sure they dont have any of that equipment.

So is the experience of a livernios who developed, tested, machined so forth the entire product important to you. That isnt to say MMR wont get the job done or even that im bad mouthing them! the question is are you willing to pay extra for the company that actually designed and tested the stuff, does everything in house, has quality control the entire way through the process.

Just my thought on it from a personal perspective.

Emay · February 2nd, 2009, 12:00 PM

Sure, lots of bland complaints in this thread numerous people put them at the bottom of any list:

MMR shortblock - ModularFords.com

Couple mixed reviews here - the concerning areas, delays in response and parts supply, burned valves in heads and lack of response by MMR.

MMR...good or bad??? - MustangForums.com

As mentioned in the first thread, a little google search will net plenty of negativity. I'm not saying to avoid them entirely. Just letting you know there is less negative talk about Livernois and DSS.

When your in the business of making power, stuff's gonna break, so the customer service and lead times getting you back in the game are most important.

Forensic had good luck so far, he's also in a different league than most of us.

05mustang_kb_charged · February 2nd, 2009, 12:06 PM

I can't say anything personnaly bad about MMR because I did alot of reading about them and steered clear of them for my build with the exception of the Billet Rear plate. See pic.

I got the heads, lock outs, and gaskets from Livernois. I would go with them since they are a little more pricey but there customer service is second to none. I know Steve has had good results with MMR but there are a lot of not so lucky people on the internet that have had problems. It is up to you about who you want to use but my vote is for Livernois. Call them up and they may be able to work with you on some pricing.

forensicsteve · February 2nd, 2009, 12:22 PM

Livernois does have an outstanding reputation. So decided since we needed a bunch of new parts to start a relationship with them.

I agree with you Emay, my car is in a different league from yours and many others....as in pretty ragged, and nasty looking as compared to drop-dead gorgeous show car. Car may be faster than some, but it's way down the list in the looks department...lol

House is for sale. Know anyone? Sign went up yesterday.

07 STROKER · February 2nd, 2009, 01:07 PM

I bought the 298 stroker from livernois...my engine builder was the one who was impressed by their kit...no more than half a gram out on the balancing...do you need it any tighter?

Mickey · February 2nd, 2009, 02:01 PM

I have read a few bad reviews about MMR on Modular Fords...never heard anything bad about Livernois at all...

JakeM · February 2nd, 2009, 02:15 PM

I've heard bad things spoken about MMR as well. D.S.S. also, but I think that was older management issues. Similar to the claims with MMR of bad customer service. I don't have personal experience with either though.

When it comes time to upgrade the bottom end on my car though, it will be done with Livernois parts.

SUHLeen · February 2nd, 2009, 02:28 PM

I wish I didn't have so many different options haha

05roush0090 · February 2nd, 2009, 02:37 PM

No thoughts about the Saleen 302 crate motor. It is stroked and forged and still offers a 3yr/36000 mile warranty. There are a few places that offer it in a short and longblock form.

Its also WAY overpriced....

usafimj · February 2nd, 2009, 02:40 PM

Haven't heard much about their engines but pretty cheap BBR 3 valve Short Block - 650 HP

I see these guys ads in mustang mags. The ads also say 3v enignes. Not bad prices and I've read that alot of people like them. Might want to call them to see if their blocks are iron or alum. Coast High Performance - YOUR SOURCE FOR PURE HORSEPOWER & PERFORMANCE!
