what is the oil capacity on my 455 and how many gallons of coolant is it supposed to handle?
i've eyed the fluid level in the radiator and checked the dip stick on the oil but i want to know the prescribed quantity of oil and coolant for my 455 with stock radiator. We're talking about a 72 regency 98.

Thanks,
Steven

p.s. the parts store has no idea, thats why i'm asking here, where i know theres people with 455's

Oil fill with filter change 5 quarts
Oil fill with filter change 6 quarts (Toronado only)

Coolant I think is about 2 gallons. I had an aftermarket raditior in mine w=but I also have the 350 motor. I probably can get 2.5 gallons in there

All I can find is a percent of ethly glycol to water, "old" books recommend 50% or about a -20 (hydrometer). I'd go with the two gallons, and rest water. You also might (in research) have to know besides engine size, with a/c or not ect.
Anti-freeze is available besides in 100% concentrate also in 50%.
