c2 distributor

[Steve D.]

I will be reassembling the 327 from my 63 convertible soon and want to get a distributor with vacuum advance (current distributor 0985 no vac). The motor is very non original: 65 block, 67 heads (462), 64? intake (3844461), domed pistons (L2166N). Based on discussions on the board I'm going to have the heads cleaned up (3 angle valve job, pocket port, gasket match). I plan to go with the LT-1 cam and mechanical lifters. Since this is not a standard configuration (no specific year and HP), which distributor application would come closest to this, and where might it be obtained? The catalogs (LI Corvette etc) have one item for 63-67 250-300 HP, and LIC asks for year and HP for hi performance.

Try to shoot for the '65 327-365 Hp combination. Almost any distributor can be "tweaked" to these specs. The important thing is to recreate the vacuum advance as well as the centrifugal advance curves. Just make it look like the 1111069 and you will be in good shape.

Re: c2 distributor

The best calibration for you configuration would be 64-65 365/375 HP, but you could start with any tach drive dist. and just recalibrate it. For the LT-1 cam you need the NAPA/Echlin VC1810 vacuum can, which provides full (16 degrees) vacuum advance at 8" Hg, which is the correct can for the SHP/FI engines mentioned above. These distributors also provide 24 degrees centrifugal at 2350 and your initial timing should be in the range of 10-14. If you get any detonation with this quick curve, it might have to be slowed with stiffer springs.

To get the most out of each engine configuration custom tuning of the ignition advance map is necessary due to the many variables including fuel octane in various parts of the country, altitude, ambient temperatures, and whether or not you are willing to run a blend of race gas and pump gas to boost the octane level.
