Is a 428???
A friend saw an engine. By stroke and bore he think that is a 428. The castings of most pieces are:
Block: C5AE-????-A
heads:C4AE-6090-G
Rod(or conecting rod???): C3AE-C Also says 85K Y B135
Crank: C4AE-B
Intake manifold(4bbl): C5AE-9425-C
Decal on avlve cover says: "INTERCEPTOR"
The engine was saw on a boats reseller. but most of the engines in there came from a car. there is a lot of Ranger's 302" V8 and Argentinian 221" Inline Six, also saw some "chuvys" 350 engines from trucks.
Anyone can tell me something about this engine?
regards & thanks for your answer,
Mariano

Block is 65 390. Heads are 64-65 352/390. Crank is 64 cast iron 427 and the rods 63-early 65 427 as well. The intake is a 65 lowriser type with the tall ports and the last of the iron lowrisers. Very possible the engine is fairly original also. I've heard of a few 390's that came through with some HD 427 parts. The crank is the same 3.78 390/427 stroke. Hard to tell 40 years later how original it is but sounds like a very early 65 390. If the valve covers and engine is original it could be a 390 police interceptor engine. The only thing is the 4.13 must be overbore as there was no C5 428 block. The 428 came out in 66 with a C6 block. Some 390 blocks can take a 4.13 std 428 bore. Worth take a look at for sure. G.

Sounds like a 406 to me. If it is, it's very valuable, rarer than the later 427's. Only in production 2 years. Same bore as the later 428, actually the 428 was just a stroked 406, since the 406 came first. Then again the block #'s don't add up, you sure the bore was 4.13 and not 4.23? There were marine versions of the 427, never heard of a marine 406.

The 406 only had a 1 year 62 1/2 to 63 1/2 production. 406 blocks are C2 and C3. The C5AE-A block is 390.

There are also C5AE 427 blocks. But he may have mistaken the 4.13 bore size, more likely it's a 60 over 390 ( 4.11 bore) One easy way to tell is to mic the piston skirts.

Yep I saw that also but he mentioned above it's not a crossbolt block. BUT it might be an industrial 427 which came with a C5 casting and 2 bolt mains if the bore is 4.23 so that's a thought as well. I understand there were quite a few 427's for the industrial/irrigation applications used and know of two such engines. Hey, you ever sell your 427 block? G.

About the only things I tend to forget now are where I set my tools down. 5 minutes later, they've disappeared into the twilight zone. 
Seems I spend more time lookin for stuff than actually doing the job at hand.

BadDad, congrats on the sale. Glad it worked out for you! I do the same with my tools at work. Put it down then it's gone and can't find it. I'm gonna start putting little bells on the things pretty soon LOL. G.
