Default Re: 401 Swap Out

Both housing are just about as heavy, the biggest difference is the water pump sits higher on the big truck housing which also allows clearance inside for the 3 piece timing gear drive. It's up to you on which one to choose as you're given 3 alternatives to make it work in your truck. I originally chose to keep the 3 piece gear drive and modify the pickup truck housing to make it work. After two failed attempts which included cutting and welding the housing then seeing several gallons of coolant on my garage floor as well as two destroyed housings, I finally broke down and went with the double roller timing chain & sprocket and I'm quite happy with that. My truck being a 68 is a lower profile design than the 60-66 so there would have been no room at all to raise the radiator, I also wanted to preserve the stock appearance and retain all the original brackets and hoses
