Differences in a C1 and C2 Ballast Resistor

[M W.]

Are there any major differences in the the two resistors if used on the same relative low horse car? Basically would a 62 work for a 64? Both being 327 low horse.

Thanks,

Yes! but the design will differ

C1's and C2's used the same 0.3-ohm ballast resistor (#1931385) through January, 1963. In early February, 1963, 250-300hp cars changed to a 1.8-ohm ballast resistor (#1957154) to reduce point-burning in cold weather.

1955 only Corvette or Car first design

the ballast resistor in your picture(roy b) is not 55 only as your post states.. that configuration of the porcelain is what i like to see on the 56 and 57 vettes.mike

Could a C1 ballast resistor be used on on a 64?

Functionally, yes.

I'll say your correct ,my brain is on 55. This ballast first design is rarely ever seen. I depend on you after 1955 ,cant afford those newer $$$ Corvettes
