i contacted CSR about this, ya can't use the heater, no provisions. However, they did tell me it would be okay to drill a hole for a 1/4" NPT pipe thread fitting to run a line to the bypass on the manifold, of course you would have to reduce the manifold outlet a little. the green dot in the pic is where u would drill the hole. i didnt do it, i decided to use a standard water pump. ]
Hi. I bought the same timing cover. from the guy in florida. What did you do with the cam bolt to make it fit. I will be putting mine on for next season and I am modifying it for my Altenator that is run off a power steering pump bracket. I am mocking it up on another 340 and noticed it is 1/4 inch away from the block with the standard bolt and mopar washer.
This moves the pump back over 1 inch and I will be able to use my lower AN fragola hose. I installed a bleeder valve where you have that dot now it is not in the old pic below.
