361/305 HP and 383/343 HP Confusion,,,,,,,,,

Let me try to explain the Dave Kempton and Doug Kahl class confusion.

NHRA Classes;
1963/1964/1965
C/SA Weight Factor was (10.60 - 11.29 Wt/Hp)

The 1962 Plymouth Sport Fury and 1962 Dodge Polara 500 with the
361/305 HP engine combination fell into C/SA.

Both Doug Kahl (1965 World Champion) and Dave Kempton (1965 Winternationals Junior Stock Champion) campaigned in C/SA with
the 361/305 HP 1962 Sport Fury's.

They had also run this combination in 1963 and 1964.

In 1966, the NHRA bumped up the classes 'one-notch', and C/SA was now D/SA, and B/SA was now C/SA.

Both Doug Kahl and Dave Kempton switched to the 383/343 HP
engine combination, after the 1966 Winternationals....

At the 66' Winternationals, they both ran the 361/305 HP combination, but in the 'New' D/SA Class

They were running the 383/343 HP combination at the 66' Springnationals.

In 1966, they were classed in C/SA, but the weight factor of the class
was 9.50 - 10.59 Wt/Hp.

What confuses everyone is the C/SA Class.
They both kept the same cars, but switched from the 361/305 HP engine to the 383/343 HP engine in 1966.
They were still running C/SA in 1966, but the weight factors had changed.
