Bare Bones Budget 400 Build

I have wanted to do a stock stroke 400 for years.Even on the cheap I would mill the heads and do as much porting as I could.I like the old Lunati streetmaster grinds.I just put the smallest one in my low compression 360 truck motor.
The smallest big block one I see is 225 @.050 on a 108.Advance it enough and it may be ok.
