Build me a Small block
my 2 cents
Don't get caught up in the hype around magazine or the engine master builds and related aura of those doing them.
I've just seen one of the biggest disasters of a build I've ever seen in my 30+ years of doing this stuff. The builder was a participant in those challenges and basically screwed the buyer... BAD! Total mismatch of parts, bad choice of bore/stroke combo for intended use, poor machining, you name it, it was in this engine. We're talking a 5 figure build here!
Talk to the locals that run hard, find a machinist that has a car that runs well. Proofs in what they actually do not what they all learned in a book. Some of the best education is the "School of Hard Knocks"! Some things in the books are flat WRONG. Look at some of the info in the Mopar books.
Something to think about... some guys sell heads based on flow numbers and promoting the big numbers. Sometimes those big numbers are detrimental to the intended end use. There's more to a good cylinder head than the flow numbers.
Figure what you want the engine to do for you and build it for the intended application. You'll save money in the long run using that approach. Some think a 560hp solid cammed SB is a streetable piece, others don't. Got to find your happy place. :-D
