perfect for LT1 SBC 5.7L and post 90's gen 1 SBC 350
Only coolant I use in my 1994 LT1 engine Works great keeping a hot running engine cool Gotta remember to mix with distilled water - it's concentrate - it's double what you're getting For pre 90's 5.7L SBC, works well keeping running and idle temps down and within safe range I'm using SPAL electric fans, so not sure how well performance would be with fan clutch or non electric system, but runs clean and cool across the operation range with 50/50 mix and a 170 degree thermostat

Vintage Cars
OEM for my cars that are 1995 and older (The Green Stuff) The Concentrate Antifreeze/Coolant is more cost effective than the 50/50 pre-mix. Equals 50% distilled WATER. My vintage Cadillac has a 5 gallon cooling system, You can do the MATH.

Tastes just like the other green coolants!
Mixes well with other green coolants. I tested it with a hydrometer before adding and it came with the proper mixture of coolant and water. It has been working well for the past couple of months.
