Plus, to get 470 RWHP out of the 346, it will not be the best "street" car. To get that power out of the 408+, you don't even need a big cam. You can keep it a lot more "driver friendly" with the bigger cubes. |
People spray 4" stroke stuff all the time. Its the overbore on the 418 that is cited as the reason not to spray, even though I am sure many still spray them.
