Ok guys so I just bought a filled 4.6 4v teskid block worked online and I didnt realize the block had been filled..... My question is can I run this on the street with a oil cooler and a water pump thats electric??? Or do I need to clean the fills out of the heads and block??? Thanks again for helping me out.
Filled block question?

I see it filled all the way up to the head ports.
Not street worthy and no need to fill a teksid block, they can handle 3000hp on a stock bore.
I think the block is pretty much junk. It won't work on the street and as badcobra has said the blocks don't need to be filled so it will have very little value to most.
Well looks like I will use my 03 cobra block to put all the good stuff in... Thanks for the input
How much do you want for it?
I may just try and sell this block... And may put my cobra block up for sell with manley rods and pistons..
Use a teksid block. The stock '03 cobra iron block is prone to cracking under high boost.
How much boost would you consider high?
Over 25psi you are at risk for cracking a sleeve. No sense building a fresh engine and not using the right parts for a high hp build.
How good are the mach 1 blocks? I can get a good deal on one right now for under 200$

Really? Cobra blocks as you put them don't have sleeves. They are iron and have no liners.
Depends on who you ask. Some say dont take them past 500, others claim 6, 7, 800. Some have lived at the high and and some have died at the low end.
4.6l cast blocks are all the same around 1000-1500hp (depends if it was casted on a monday or friday) 
4.6 wap block most say 500hp-600 but most get away with 1000hp. 4.6 teskid 2000hp.
Didn't you have a running car you just built??

if you go aluminum, make sure the shop know how to deal with it. Aluminum moves around a lot with temperature change.
Yea I do have a iron block... I could clean it up and use it if I needed too
