Thinking of going BB...

True depending on how far you wanna go with the build and on what budget.

Hey Sinister has the block been bored and you honed it .010? or do you mean the block wont hone to take a piston? and you have to bore it or is the block poo-poo(max bore size now) altogether?

If you gotta bore and you got the cash it I'd buy the KB's and go with 452 heads. If you get another block save that 400 and sleeve it up for a bigger stroker later on.
