I drilled 1/16" holes I believe on my TQ with a MP508 cammed 340-4spd and also trimmed one coil off of the metering tree spring to make it lighter. 22 intial/38 total timing advance also with no vacuum advance hooked up. These mods and adjustments do work and normally help with larger cams on street cars.
