I am an anti MSD person. I have found that MY replacement rate on them was alarming and was irrelevant to where they were located. They seem to have an alarm clock in them whereby they just shut themselves off, never to ignite again.
If you are a racer then that would effect you less since the nature of a race car is just to constantly be changing parts in the car and you likely wouldn't ever notice that the brain's only last about a year.
I am going to go to IR FI with the pantera and use a Haltec CPU. Haltec has given me a patch in diagram for the Ford TFS and when I get to it I will get the Duraspark patch from them also. THEN I will find out how adaptable the Duraspark is. Haltec keeps saying that it will work fine. I always get nervous at the "no problem" comments people make though.
As far as a Boss 302 in a 'goose I am guessing that the hassle is the accessories hook-ups in the car.
Personally I thik I would stay with the original 302 block, heads, dampener, etc and go to a 347 stroker with an aluminum flywheel. Race port the heads and mabe try the Weber IDF carbs in it. That would sure give everybody a heck of a'goose for sure.
