408 all the way

TheGmKiller331

408 is a lot safer i think.I just dont like to have my setups at the max thats why i went with a 331 instead of 347.But thats just me.You will definately need some high flowing heads to help that moster breathe.

how far should i go if i only want around 450 hp out of a 351w?

It is pretty easy to get 450 hrosepower even at the wheels from a stroked 351 with heads, cam,intake

Obsol3te

I bet you could mabye pull 450 with a 357 stroker, 10.1 cr , ported heads, and 550" + lift cam. And you could always throw a little nitrous into the mix
