A big thanks for advice received here on site. My little Y Block is running really nicely. Very responsive with good power. I have ditched the unilite Mallory distributor and replaced with a rebuilt and modified 1960 FOMOCO unit with mechanical and vacuum advance. Running an ACCEL 20-20 breakerless module and ACCEL superstock coil. Have set total advance at 38 degrees and have limited total mechanical to 22 degrees (11 degrees at distributor). I still have some adjustments to make but will wait as I plan to change my diff gearing. I will be keeping an eye out for some slightly lighter springs. Anyone got any tips on spring weight size or where to source?
Y blocks are fun to mess with. They seem very responsive to inexpensive upgrades. If the insides are clean, a PCV will help keep it that way. In our country, we use Aerostar front springs, or custom wound.
Yes sorry guys distributor advance springs. I will need to go lighter once I drop the diff gears from 3.0 to 3.89
