Sorry, I just saw your message.
A previous owner did my swap. I'm not sure what mounts they used but the're only attached by the two of the four bolts. But it's solid so I guess it works. Drivers side header tubes were massaged to fit as well. Clearance is an issue. I have the stock intake and air cleaner and I only have 1/2 inch to spare.
did you do the swap yourself? I'm getting ready to do a 460 swap myself on our 68 and the 460 as it sits is 1" taller than the 390 and then if you use the Dearborn mount kit it kicks it up another inch. Just trying to figure out if I'm gonna run into any problems or is there another option for mount that you used.
