Rich or Lean idle?

<< < (2/2)

77cruiser:
How much more timing did you try, did you recurve to dist. so it didn't over advance in the upper rpm's?

Cliff Ruggles:
I've used the 041 cam with 6X-8 heads on 455's, and Rhoads lifters.  It actually worked pretty well, but they really shine with higher compression.

For sure I would NOT use a Comp XE cam in one of those builds, not enough seat timing and LSA too tight, they don't have a fighting chance of making great power or working well anyplace.....IMHO.....Cliff

blazer74:
For what its worth I have a 110lsa 268 cam in  sbc and I have to go from 3 turns out best idle to 4.75-5 to get the stink out of the idle. I have a good idle either way.
