Thread: 410 block question

Tweet

What is a 410 FE block worth? bought it as a project years ago for $1500.00 came with a 30 over 428 crank and polished 427 rods has laid around disasembled. I was told these are mercury engines that were only made in 1966 and 1967, a friend told me these are binging $5000.00 now is this true? dgpalm@bresnan.net David

The Merc 410 used a C6ME or C6ME-A 390 block with a IU 428 3.98 stroke crank. The 360 also shared the same block as the 390 and 410 and all have a std 4.05 bore just the crank stroke difference. The C6ME or C6ME-A casting number is on the right side of the block. Depending on which 427 rods you have will determine the value. Tell me the numbers on the side of the rods. The IU crank in worth maybe $400 at .030 on mains/rod journals. The C6ME and C6ME-A 360/390/410 blocks are plentiful and maybe worth $500-600 max if still std bore and good shape. Depending on what rods you have you might break even on your investment. What is the date code on the block? It's a number/letter/number(s) sequence below the oil filter adapter mounting pad. On the small angled part of the block there.

Looked at paper work and it says 406 - looked at block and under the oil filter aria is cast 4f3 and looking at the back of the block there is a welded MA
Thanks for the help

Well a 406 is a whole nother deal. 4F3 is a date code of 64/Jun/3rd. The 406 was a 62 1/2 to 63 1/2 only deal till the 427 first came out in late 63. But there were a number of service blocks which had very THICK cyl walls. Basicly the 406 service blocks can go to 4.23 std 427. Is there a casting number on the block? Also look for a "HP" and the block should be a solid lifter style with a oil pressure releif valve above the rear cam plug. Is the crank a 406 crank also then? If the rods are early 427 they might be C3AE-3. Look on the crank for a casting number also or any letter/number like IU, IUB, 2U, 3U etc.. Ford used full casting numbers then went to a simpler ID later on cranks. All these things will really help ID what you have. G.

Hmmm welded MA? Never seen that one. I've seen A, C, P, F, III, and a few others that escape me now. Curious to see what casting number it has when you find out. The only thing that comes to mind is marine application but that's only speculation on my part. lol, G.

had to fix plumming problems today, jack hammered up the floor and took a foot of roots out of drain pipe, I am hoping to play a little in the garage tomarrow after patching back the floor. Thank you all so much for the help this one has been a head scratcher.

Hey no problem. I'm trying to find out what that MA on the back is also. I'm thinking the MA is a sandscratch from the foundry as most were. I'm feelin for ya on the drain and roots. I had half my yard dug up a few months ago myself. Not my kinda fun. G.

MA on the back is large welded on it, just like the C on the back of my 428 cj engine. I found some more casting numbers Block came to me disasembled and paper work says it now has a 428 crank and 427 rods that have C6AE-E on them the block has C4AE and 015A below it the cam has SEG3 on it, I also noticed the rear maine has C2AE on it. I am getting ready to take my 428 CJ to the machine shop so I was hopeing to sell this 406 to help finance some of the rebuild.
what a weekend, pipe is all fixed and floor is all patched back, I am looking forward to going back to work to rest.

Ok the only blocks that have that casting number C4AE-6015-A are a 64 352 with a 4.00 bore, 390/361/391 with a 4.05 bore and last a 427 with a 4.23 bore. Also the 427 would have crossbolted mains so that would be easy to tell. It could have been a service block possibly for a 406 made out of a 427 block. You can knock out the freeze plugs and gap the wall cores to see. A 17/64" drill bit shank will fit snug between the cores for a 352/390 block. A 13/64" bit for 406 wall cores and some 361/391's. And 8/64" for 427 wall cores. If the block does not have crosbolt mains it might at least have the crossbolt knorbs or bosses present there. The 428 crank will have a IU, IUB or IUA on the 7th counterweight. The C6AE-E rods are nice LeMans rods with capscrews from the 428 SCJ. The crank and rods are worth $1000 for both. The block once you tell me what you find will have a better idea what it is. I'll email someone about the welded MA to get his input as I'm coming up blank. G.

Geeze I'm slippin...forgot to mention if it is a 406 service block it would have a 4.13 std bore like the 428 had. Also the C4AE-A 427 would have the "HP" markings by the casting number. The std 406 casting numbers are...
C2AE-J
C2AE-K
C2AE-V
C2AE-BD- also crossbolted
C3AE-D
C3AE-V
Also is the block set up for solid or hyd cam?
