Thanks David and Alan for your replies. Last Saturday Mike and I went into that fight leading with our chins. We thought we could just line it and fabricate some brackets. I had not even bothered to check any internet sites since about the time of the first several posts. We learned our lesson. I tried the suggested searches as much as time permitted and they offered some help. Today I went down to A Plus, a local hot rod store, to see if they could tell me more. The guys there are great. They could not give practical advice on this particular swap but could order the motor mounts cheaper than any I had seen on the internet. There was a customer there who talked with me a good while and made several generalized swap pointers. Meanwhile Mike has remembered some one who he believes has done several of these swaps and is trying to catch him.
This is where we stand now. Tomorrow I will order a set of mounts that will mount the 454 to the sides of the frames. Mike wants to use the brackets that will move the engine forwards ¾ inch. The reason for this type of mount is to allow the larger HEI distributor to be used. He may not use an HEI but thought that it would be additional insurance that he will not have to alter the car’s stock fire wall and will give just a little more margin for error. None of the manufacturers that we could find made any comments about this interfering with the oil pan and tie rod clearance so hopefully that will not be a problem with the after market mounts. Sanderson advertises a header to fit this application and is supposed to have enough clearance for a stock or 605 gearbox—not cheap but a potential working solution.
Hopefully with the appropriate engine mounts, we will be able to line everything up and make a transmission cross member. That “should” be doable. I will let you know what happens. Thanks for the tech support.
Rick
