Oil - Valvoline 30 weight Racing, as recommended/originally installed by my engine builder. Plenty of ZDDP. Would consider Brad Penn or new Classic Car Oil from Classic Car Club of America. I have roller rockers anyway - but I want to be safe.
Power Steering - ATF as recommended by Pontiac. Tried clear "modern" power steering fluid, too noisy.
Brakes - DOT 3/4. Usually not too picky here about brand.
Read End - Valvoline 80/90 dino with GM posi additive. Tried semi-synthetic - too noisy. Full synthetic would be worse.
Tranny - Valvoline Dex/Merc
Anti-freeze: Real full-strength Prestone only. Mix it myself with distilled water. Refuse to pay extra for somebody's water in today's 50/50 mixes.
Gas: Real 100% gas 93 Octane Premium from Conoco. I always add Sta-bil to a fresh tank of gas. Today's gas sours quick.
Additives: Considering stuff from these guys after recommendations:
