408 stroker questions

Having a 360/408 stroker built for my 69 Barracuda Fastback. Wondering if anyone has experience with a Miledon oil pan. The folks at Miledon tell me I they have a 7 or 8 quart. Part #30941 (7qt) and part#30940 (8qt).
Wondering if there will be any clearance issues with K frame? They tell me the only difference between the two is the 30940 is 1 inch deeper (8 3/4 inches). Builder is recommending the 8 qt pan.
Also wondering if my 340 motor mount brackets will fit the 360 ?
Any info is appreciated.. Thanks
