    I got mixed results on the 6272292 heads looking on the NHRA tech site.

    http://www.nhra.com/tech%5Fspecs/classification/

    For 1971: 300 HP 402's and 365 HP 454's - 105 cc.
    For 1972: 210 and 240 HP 402's and 230 HP 454's - 105 cc.
    For 1973: 215 and 245 HP 454 - 110 cc.
    For 1974: 235 and 270 HP 454 - 110 cc.
    For 1975: 215 HP 454 - 112 cc.
    For 1976: 225 HP 454 - 112 cc.

    Not sure how it lists as three different volumes, but I'm betting it's a 105 cc head.
