That's true, It does have to be big enough. There should be a rating on the cooler when you buy it. I ran a cooler only on my 40 chevy panel truck w/400 turbo, shift kit, H.D. clutch pack & 2,800 stall converter and a rather healthy 454. Pulled a pop up camper to and from rod runs almost every weekend. Raced it periodically, never had a problem. I DID make sure it was a big enough cooler tho.
