408 stroker Questions

Hey guys, I'm new to this forum, and I stumbled across some articles on the engine masters. So I'm having some thoughts about building my own Ford 408 stroker using either a World Products man o war block with 2.75 mains and 9.2 deck height like a cleveland, or just a cleveland block.. Im from Australia and these are thick on the ground here, and I'm thinking a nice little combo using CHI 3V 225cc heads would go great in a 3400lbs car.

Now.. I'd like to have an engine thats internally balanced, so I guess that means a Scat 4 inch stroke crank using 6.2 or 6.125 H-beams..??

I'm up in the air about cam selection thats my problem..Using dyno sim and dyno2003 its telling me the cam should be small like a Crane F-256 and it makes 600hp with it, which doesnt seem right to me

Pistons may have to be custom, with about an inch or so compression height and getting between 11.5:1 and 12:1 depending on chamber cc

Question is.. Do you think that 600+ HP is possible with that sort of cam or should I go bigger..?? and do I need the 4.00 stroke 6.125"+ crank/rod combo to internally balance??

Any suggestions would be greatly appreciated..  

ever thought of using a 400M block? CHI heads will work on that too. I am on the fence too all I need is a 4.250 crank to make my stroker short block.
600hp is not hard to make with the f256 cam, funny thing is I have one of those someplace in my collection.
Are you still in Australia? the 351 Clevland blocks here seem to be thin walled are the aussie blocks cast with thick cylinder walls?

sOUNDS LOKE A NICE COMBINATION.i HAVE A 9.2 dART BLOCK WITH cchi 218 3V heads.Topped off with a 6;71 blower and dual holleys,with a mild cam it makes 690 hp and best of all 655 lb ft of torque.A word of advice do not buy anything from Speedo;Motive in Covina calif.They are dishonest and do lousy machine work.
