Dist for a 2.7 RS Options

[Red-Beard]

As I started final assembly of my 2.7 RS spec motor (S cams, RS P&C,2.7 crank), I found the mechanical advance dist cap is cracked. It's a Marelli and it was setup for a 2.0T. I have a 2.7 vac adv dist, a Bosch. Will this work? Am I better off with something else?

Yes, a 2.7 distributor will not fit a 2.0 case. You are safe with a distributor out of any 2.0 or 2.2 motor...the "e" distributor should do nicely.

You'll notice that the 2.7 distributor has a large area cast into it to allow for ignition timing adjustments, rather than the plate/cinch bolt setup of the earlier distributors. That area will prevent the distributor from seating properly in your early case. I have actually seen people machine off that area to use it with an early case.

If you need a cap for the Marelli, I can probably point you to some used ones local to you.

Oh, just an afterthought...you may want to avoid cast iron distributors from pre-68 cars. They use two piece points that I always seem to ground out and require modification (albeit minor) to the cap.
