The 1947 Dodge Build

[mpgmike]

I love the idea of a 318 or even 273 stroker, because it keeps the bore small for better flame propagation, yet wields the longer stroke for massive torque. In my opinion, for big engines, the 413 was a much better balanced engine because of the smaller bore versus the 440. (In fact, for 2-3 years Mopar made a 383 RB engine!) Just use heads that breathe appropriately for your RPM and power requirements.
