Aluminum block...or steel...

need advice. I am starting my build up here in the next month. I need to know what block to go with. I want the weight savings of the aluminum block, and the strenght from the 6 bolt mains. I have a line on a 93 MARK8 Shortblock, crank/rods/pistons/oil pump/picup tube/pan for $300 to my door.

Bottom end plans...
-Cobra forged crank
-manley "H" beam rods
-JE forged pistons...tad lower compression
-.020 over bore
-high volume oil pump
-97/98 Mark8 oip pickup tube
-93 mark8 oil pan

Top end plans....
-Comp cams..or blower specific cams
-comp cams valve springs
-Stainless steel valves
-3-angle valve job
-port my 97 SOHC heads by renegade

and new chains...gaskets...all the smart things you do on a rebuild....

I am going to be running 10-12# boost on this engine
SO...aluminum...or go with a steel?

My opinion would be to go with the aluminum block for weight savings. There are Cobras out there puting out 600 plus HP with aluminum blocks without problems. Ther say ford went with a steel block on the 03 Cobra for a reason. Cost was not it. I know that they are more prone to flex under high HP conditions. You may want to shoot someone like KD or JL a PM to get their opinion. I know Dennis Reinhart' Mark is well over 500 HP with his aluminum block and I think he is running more boost than you are planning.

PS. If you do not want that Mark VIII engine, just have it sent to me. I'll pay $300 no problem!
