In the next few months Im going to build a bigger motor to handle more power.. Im torn between an 390 and a 408.. the goal is to have a motor that if needed or If i want to make stupid power can handle 1000+ rwhp... I don't want to hear or get into an argument about why I need this much power, or you'll never use it or blah blah blah.. Im building what iv wanted and thats it

I would like to know which block (iron or a sleeved aluminum) you would choose and why.. Your information will be much appreciated
