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

Personally,

I would NOT use MMR if they were the last company on Earth selling engines. Some like them, some have been severly burned by them. From what I have PERSONALLY seen of their stuff is that they do not have any quality control. That is on top of their arrogant attitude as well. Their shortblock are cheap for a reason - Lack of Quality, workmanship, etc...

You are better off going to a good reputable shop.

The best way to increase displacement and make power is a 5.0L Big-Bore. From what I gather, you don't have the funds for a Big-Bore project. Next on my list would be keeping the 4.6L displacement. 5.0L Strokers make less N/A power than the 4.6L does.

Cheers.
