Arrow My Recession Buster Engine Build

since my funds have ran low and i really want the car to move from its hiding spot, i decided to do my own "Nick McKinney's Recession Buster." for those who dont know what im talking about, heres a link:
http://forums.corral.net/forums/gt-s...on-buster.html

i was just going to snap pics as the build went then do a thread but decided to go ahead with a build thread. heres what i have so far:

i picked up a 98 mark vii engine for $300. i even got to hear it run before being pulled.

here is the hand ported pi heads.

here is the other head sitting behind the comp 270 cams and manley ss intake valves. these valves will give me .030-.040 more ptv clearence and better flow.
Click the image to open in full size.

here the intake i scored for 200 shipped on ebay. its an 96 ford racing svo aluminum manifold. its been ported through out the entire manifold and even been ported for pi heads and coated with heat shield paint (what the seller said)

I hope im not about to break a heart, but are you 100 percent positive thats a mark 8 motor. The reason i ask is because the "intech 32 valve" cover on the vavlv covers. I cod be wrong here but i thought the intech labeled was for the transversly mounted 4vs in the continentals and if this is the case that block isnt going to work because the bolt pattern for the bellhousing is different alogg with the motor mount locations.

yea, im sure. i thought the same thing til i picked this up. i guess either in 97 or 98, ford started doing the coil on plug in the mark viii's. this having these valve covers will add 100-150 to my pocket on getting funds back out of parts. ive done made back 170 on selling the intake and coils. i wont have nothing but time in this short block

Didn't Mark 8's have the the TB at the back of the engine? Also why did you buy a 4V complete engine just to put 2V PI heads on it, or am I missing something?

At junkyard he wo of paid the same for another 2v, with this setup he gets an aluminum teksid block and a bump in compression due to the 4v shortblock combined with the pi heads, so he makes a little extra power if i remember correctly.

Its lookin nice! Dont forget, your front end of your car is going to rise slightly do to the lighter engine. What are you setting your car up for? Drag racing? Twisties?

What are you going to do as far as exhaust? Lts?

Keep us updated!

yea, this would be like throwing flat tops in your current motor. you do need a stae 3 cam or bigger because of the compression. guys, read the thread i posted in the op.
yea the car is setup for twisties. there will be updates later tonight, with pics!

93-95 had the throttle body at the back, 96-98 got a revised intake manifold like the one you see in the pics.

Incorrect. The 93-96 had the old style intake, the 96 got the "Intech" badging, but nothing else; the 97-98 had the new style intake.

i took a intake valve im not using and grind flats on the upper part of the stem

i used a hex quickdisconnect collor to drive the valve

i then cut out 80 grit sand paper with the sticky on the back side and attached it to the valve

Click the image to open in full size.

i then installed the valve in a spare bare head, put the head onthe engine with the locating dails and put the quick disconnect on the valve. i used drill to spin the valve to make my own valve reliefs.
Click the image to open in full size.

i repeated the process for each cylinder. i cut the reliefs .050-.058 deep

Nice! for each piston you did, did you bring it upto tdc first? Because if not, they will be off and wont do anything.

This would be a very bad idea with boost, the stock shortblock wont handle it with a compression that high.

Yeah 11-1 is high for boost. I just didnt know that the CR would be that high just by putting a 4v short block in
