I think he's looking at Galen's white book. It lists a:

'SPECIAL ORDER PARTS 2875255/ "LESS CAP & ROTOR" 2875327/ IBB-4401A 1968 426 HEMI BOTH (manual and automatic) A (body) TACH DR'

I've tried to accurately reproduce the listing but the original is a little jumbled.

"We live in a time when intelligent people are being silenced so that stupid people won't be offended".
