Okay hears my pitty story….my 03 mach 1, which had a petite 29,000 miles under it’s belt, developed a knock in the engine…it’s a connecting rod….and it appears as if it’s going to cost me about $2000 when it’s all said and done to just have the bottom end rebuilt with stock components

So this is what I was thinking….MMR makes a variety of 4 valve short block I can just about afford…. between $3000-$2500…I’m currently working my way through college and money is hard to come by, however, I’m not willing to sacrifice quality and I might as well have a strong platform for future upgrades…forged internals are a must for the power I plan on making a couple of years down the road…The only thing is the MMR blocks I can afford are all iron so I would be gaining some weight ditching my aluminum block

So my questions are:

Is MMR (modularmustangracing.com) the best company to go with for a short block???

-How much more does a iron block weigh over the mach’s stock aluminum block???

-For right now I have to use my stock heads, cams, and intake so would I see a initial power increase if I went to a 5.0 or a 5.4 over the 4.6???

-What would be the most cost efficient way to get more power out of a higher cubic inch engine like a 5.0 or 5.4 if I do go with one in my mach????

Thanks for reading and I really appreciate any suggestions

MMR is Deff the Best company to go with!

40 lbs, and if you plan on going with a power adder in the future stick with a standard bore and stroke.

+1 no more than a 5.0 stroker. MMR is a great company w/ an awesome reputation. You caould just offset the weight w/ a aftermarket K-member kit when you get some cash saved

Nice, you posted this in Tech and Talk sections.

http://forums.stangnet.com/772878-short-b-questions.html

Like I said earlier in the tech thread. MMR is NOT a good company, do a Internet search on them and you will find they have plentiful unhappy customers and many complaints with the Better Business Bureau. Not something you will find with a good reputable shop.

5.0L Strokers are a huge waste of funds if you intend to stay N/A. You will make less power with it.

Just buy a rotating assembly that is .020 over and have a local machine shop bore and hone your aluminum block and assemble it you'll be less than 3 grand that way
