Default 402 or 414?
I am looking to build a bigger cube engine real soon. I was wondering what would be better. I am going for a setup that would be more streetable but be able to go the track and run good times. Should I build a 402 with a new 6.0 iron block or buy a MTI 6.0 block that has been bored .060. The reason I mention the MTI block is I can buy it for a really good price, thats the only reason I am considering it. And if I do what kind of problems could I be looking at with it bored that much? I also want to be able to use nitrous every once in a while. Thanks for the help.

I was also thinking of a 408. How much nitrous could those pistons handle.

I agree with the 408 idea. LME 408 iron block is what I'm saving for as we speak
