Dropping down to 87 octane with alum vortec heads.
Dropping down to 87 octane with alum vortec heads.
Just thought I would ask.
Due to new tax's on fuel here I am dropping to 87 octane and am using AFR vortec on a 9.5:1 383- truck. Anybody here have a decent SA main and extended table for EBL usage, I think GM fastBurn would be similar. If not I'll see about using iron vortec or corvette L98 alum choices in supplied bins.
