Bugg@red about with good old distributors, points and mechanical fuel pumps on my miniblock 318 in a 1967 Bristol for years.
Stuck in a dragster fuel pump, dragster electronic distibutor and after a month a load of cable as thick as your thumb to arrest the smoke emitting from under the dashboard - transformed.
Now the Only visible smoke is in the rear view mirror - two sources - both expensive - tyres last 7000 miles and a set are €2000 and leaded gasoline 12mpg- but it's the kids money!
