Mark 8 shortblock.

So I came acrossed a deal on a bottom end from a 98 mark8 with 70k on it($100). It's aluminum. Is this worth the time and effort to tear down and re assemble for my gt. What are the pros and cons. Any common issues with the aluminum block. Would I be able to use termi heads and an 03 timing set on this. Is everything pretty solid on these as well. please help.

Not the most knowledgable in terms of what your asking but I do know the 03/04 Termi have a iron block to support aggressive power add on's. This is why it's referenced as "bullet proof". I would say as long as your not creating a monster power machine then GO FOR IT BRO !!!!

If that's the case then why is there an occasional reference to the aluminator. I always thought they were aluminum.

Because the 99-01 had the aluminum block which was replaced in 03/04 cause of the increased power FYI.

Yep. I'd still get that block though if you do all the work yourself.

If anything you can pick up the block for $100 like you said and if you decide not to use it.. Turn around and sell it for like $250-$300.

Reason I say this is because I picked up a 5.7 350 Chevy block with 70k on it for free and sold it for $350... Lol

How much do you think a set of bare 03 cobra heads with a full port and polish would go for. I have the valve train and timing set minus cams and springs to go with.

Pretty hefty. I think ford racings cost for an assembled head (mach 1 spec) was $1200 a side. Plus your "full porting" your looking at 2800$...

I only ask because the guy I bought the valve train that I thought was for a 2v has pair for about 200$. I thought about flipping em to make some $ but I don't know how easy they will be to sell without cams and springs.

Aluminator motor came out after the 99-01 cobra and any early Teksid block is an awesome block to have. They are extremely strong when prepped properly and can handle pretty much anything you throw at it.

also you will have to changed the crank because it isn't a forged piece like what comes in the cobra's. As for the block itself though, very strong piece to start with. 04 heads and timing set should work with it to, will need an 01-up intake though.
