Depends upon your required installed height or whether your heads accept a single or a double spring.hi ordered a comp cams 276 ah-10 but cam card gives no spring specs
called comp cams 2 different times and got 2 different numbers one is 924-16 the other is 926-16 confused on which to use if either?
also whats a good full gasket set kit
omc king cobra decked block
forged flat tops
d3's ported per scottys site
valve guide bosses cut
stainless cj valves
victor ( lem evans)
850 marine holley
crane hi 6 ignition
CJ valves in a D3 head aren't a good match.
