The C6ME-A block could be a 352,360,390,428, or even a FT 330 or 391. That same number was used on different bore blocks. Best to measure the cyl bore. 4.00 bore is a 352, 4.05 a 352 and 390, and 428 a 4.13. You can also measure the inside wall core thickness. I'd say with the 3U 390 crank a good chance it's a 390 block. The C8-F intake is a 390 GT intake. The C5 I have a no confirming listing yet. I show a C5AE-9424-C as a 1x4 low riser and a C5AE-9425-E as a 2x4 aluminum lowriser. You sure that's the right number? C6AE-R heads nice 352,390 heads. The C7AE-B rods were both small bolt and large bolt rods depending on the engine. The large bolt were common to the 428CJ. The C6 rod is the same weight as the C7's and also used in numerous applications. G.
