I have an unnatural interest in the /6

A turbo-charger overcomes the slant's poor-flowing heads, and has gotten one guy into the 10's in 1/4 mile. Seems turbo would be much harder for a small-block, given you need 2 turbos (or complicated plumbing) and much less space.
Nothing against the slant, or what you wrote...... but for the record there are many, many, many small blocks in the 10's without the turbo.
