So looking for a pretty bulletproof setup. Looking to make 650rwhp but want the ability to change a pulley and jump to 800-850.

So far looking at:
Dart 4.125 SHP block

callies dragonslayer 3.75 crank
Diamond pistons for 6inch rod
http://www.cnc-motorsports.com/diamon ... h-pistons-4-125-bore.html
callies 6 inch rods

or
http://www.summitracing.com/parts/cpi-a6000cs2a2ah/overview/

And ARP hardware throughout

How does this all look? CR will be 9.5:1.

I have heard the compstar will be fine but a rating of 700flywheel is unnerving.

Great parts choices in my opinion.
Not only are the crank and rods great quality, but they tend to hold their dimensions years later.
My piston of choice is the SRP.
But the best balances you can afford on it, and best flexplte as well.
