Short Vs Long Block

I was woundering what the difference is between a Short block and a long block? What type (Short or Long) of block is in the 2003/2004 Cobras and Mach 1s? Which one is better for drag racing?

Re: Short Vs Long Block

Short block = just the block, and rotating assembly (pistons, crank, etc).

Long block = Short block plus oil pan, heads, and sometimes upper and lower intakes.

The 03/04 cobras and mach 1's have the same block, but have different internals and top end components...ie cams, head profiles, and intakes.

The 03/04 cobra short block would be better for drag racing because it is forged already. The long block would obviously also be better as it would have the forged internals as well as the supercharger. lol

Re: Short Vs Long Block

Ok cause Ive been looking at buying a used high milage GT and building up a MMR stroker block. So the only difference is the stuff on it alright.

Re: Short Vs Long Block

So if Im going for more of a Kyle custom engine go short block, or long block just in case I screw something up? What would you guys go with?

Re: Short Vs Long Block

If money isn't an option, go long block. Then you can get custom cams and everything that you want all at once assembled.

If you are doing this on a budget, you could get the short block and reuse your top end. However, the only reason to do this would be if you were seeing issues with your current engine since if you reuse your stock stuff, the short block really won't be giving you anything.

If you plan on sending your stock heads off to get ported/polished/cam swaps/etc, and your upper and/or lower intake to get ported, then you could save some money over getting all new stuff with the long block.

So, if you want the most out of your new motor, you either have to get the long block with all new high performance stuff...or you will need to take your stock stuff and get it all worked out to higher performance specs and just get the short block.

If you won't be doing the work yourself, it would be best to get the long block as you will save yourself a good bit in labor you would accrue in the tear down and re-assembly of your engine. A long block just drops in...less labor.

Re: Short Vs Long Block

i personally like the 94-98 body the best, 99-04 like upton said is a good body as well. You'll just have to go through extra measures to lighten the crap outa them... foxes were the one of the lightest mustangs, and they are one of the cheapest and they fit pretty much any engine supposedly. Just remember its all personal preference.

Re: Short Vs Long Block

if you really don't care i would say a fox body just cause they are lighter :S personally i don't like the body style that much, but you can make them extremely fast and it will be the cheapest body to find

Re: Short Vs Long Block

you can't get a 99-04 with the 4.6 below ten seconds. Unless you got a **** ton of money and skill

79 with T-tops? was it custom done? T-top wasn't an option on the fox till 81 or 82 i believe.

None the less thats the only way i like fox bodies but they are weaker structuraly and will need reinforcing.

Depends on your definition of **** ton of money....it can be done with an 03/04 cobra for around 5k and race gas.

My bad I meant 1985 not 1979(I was reading a article in MM&FF about a 1979 hot rod). I do know that any convertiable, T-Tops, and Targa Top will be weaker structuraly but I was looking to just restore it to factory spec. But yeah its a 1985 not a 1979.

No man I was looking at a custom built 5.4 or 5.0 4v DOHC to put into a 1999-2004 body.
