Check the top post on cast impellers for a good cooling tip and Running Hot on the HiWay about timing, etc. You could also search some of the other posts.
PY is a great resource for info. FGF is just a percentage of Pontiac owners and PY has many Pontiac owners with valuable knowledge. I figure it's better to give you a link than to repost everything ...lol. I hope this helps.
and many of us are on both sites! LOL
PY is great for Pontiac general stuff...engines, etc... but FGF is 67-69 Firebird specific ,and if its a 67-69 Firebird question , mostly better answered here...for "general" pontiac issues, PY is a great resource
