ok trying to pick my ignition. ( in case i haven't said it; Thankyou for helping me!)
I have 1968 mustang convertble, 200 cu in, 3.3L in-line 6.
Isky 256 cam, 202@.050, .450 lift, 112LSA
I am putting on a turbo and intercooler. blow thru a holley 8007 390cfm 4bbl progressive carb.
recently purchased duraspark2 dual vaccuum 30-2670 and mr gasket 925D( only 1 spring).
will I need the 6421 suit me or do I need the 6530. is the 6462 better than all 3. all look great. the 6530 is about $100 more than the 6421
Let me know,
