What crank is this

IT HAS BEEN AWHILE SINCE I HAVE BEEN ON HERE, AND I HAVE FORGOTTEN HOW TO LOOK UP A RESPONSE THAT SOMEONE HAD GIVEN ME A LINK TO. ANY WAYS ... TRYING TO FIND OUT WHAT THIS CRANK IS. I AM THINKING IT MAYBE A 352 ( 2T )?? THE BLOCK DOES SAY C7ME-A BUT I HAVENT FOUND ANY THING ELSE TO CLAIM IT TO BE A 428 BUT THE BOOK I HAVE. MAY TAKE IT TO THE MACHINE SHOP THIS WEEKEND FOR BORE AND STROKE MEASUREMENTS. ANY SUGGESTIONS ON ID NUMBERS FOR THE 352??? ANYWAYS ... UPDATE FOR THOSE THAT MAYBE CURIOUS. TORE MY 69 F-100 APART.KEPT ALL OF THE GOOD PARTS SENT THE REST DOWN THE ROAD. DOING ANOTHER 1969 F-250 RANGER. PUT THE 2X4 CARBED N.O.S. 428 IN IT WITH A C6. DANA 60 5 LUG IN THE BACK (KEPT THE F-250 SUSPENSION) PUT 1975 1/2 TON DISC BRAKES UP FRONT. STEEL AND WOOD FLAT BED THAT ENDS AT THE BACK OF THE FRAME. (7ft 2in.) 7 WIDE 255 X 60 X 15 UP FRONT AND 12 WIDE 295 X 50 X 15 IN THE BACK. WOULD SHOW A PICTURE BUT I ONLY HAVE A CAMERA PHONE THAT WILL E-MAIL THE PICTURES. THANKS FOR THE HELP AS ALWAYS SCS..

2T is a 3.50" stroke 360 or 330 cast iron crank.

Thanks Again Ffr428!!! Is There Any Way To Tell If It Is A 330 Or 360??? Scs

If you mean the crank they are the same. The 2T was used in both 360 and 330 applications. The heads might tell you more if your talking about the engine. 330's were FT engines and had the heat crossover in the center vs offset like the FE's. The bore size of the 360 is 4.05 stock like the 390. The 330's have a smaller 3.975 cyl bore. If you know the head casting numbers post them and we can tell what they are. Glad to help.

The Heads I Believe Are Just Standard Fe Heads C8ae-a.i Have Not Pulled The Heads Off Yet. Just The Oil Pan So That We Could See The Crank Numbers. The Block Reads C7me-a. Which My Book Claims Is A 428 Block But I Havent Found A 428 Casting Behind Any Of The Freeze Plugs. Thanks Again. Scs

The C7ME-A casting number was used on lots of blocks besides the 428. 390,360,427,410 and some FT blocks besides. Your right as most books list this as a 428. Another generic number. But the mystery will be over when you take a head off. Even if it is a 4.05 bore, drill bit the wallcores. You never know. I've had 428 blocks that had the "428" cast inside the center freeze plug and or in the bannana shaped coolant slot. And some that have had no "428" at all. If you see the reinforced crank saddle webbing that's a good sign. It could go either way. keep us posted on what ya find out!!!

COULD YOU PLEASE EXPLAIN WHAT YOU MEAN BY ( DRILL BIT THE WALL CORES ) ? I MUST ADMIT I HAVE NEVER HEARD OF THIS BEFORE. BE VERY INTERESTED IN LEARNING ANOTHER TRICK. PLEASE EXPLAIN SO THAT THE SLOWW CAN UNDERSTAND:confused: THANK YOU VERY MUCH. I WILL HAVE THAT OTHE BLOCK PULLED APART MORE TOMORROW I THINK. BUT I DID NOTICE THAT IT DOES NOT HAVE ANY REINFORCED WEBBING ON THE CRANK SADDLES.. SO IT IS PROBABLE NOT GOING TO TURN OUT LIKE I HAD HOPED.:CRY: BUT I WAS LOOKING AT ONE OF MY OTHER BLOCKS THAT I HAVE . IT HAS A D2TE BLOCK CASTING NUMBER WHICH I DIDNT PAY MUCH ATTENTION TO AND I NOTICED TO DAY, THAT IT HAS THE EXTRA MAIN WEBBING AROUND THE CRANK SADDLES. COULD THIS BE SOME THING DIFFERENT THEN WHAT I THOUGHT OR ??? ANY FOOD FOR THOUGHT WOULD BE GREATFUL.. THANK SCS

Well let me start by giving credit where it's due. the "drill bit test" was devised by Dave Schouweiller or "Shoe" as he's known over on the net54 forum. It's a simple field test to see what cyl wallcores FE and FT blocks were cast with. This will give you the basic idea what your dealing with thickness wise and a sonic map should be performed when boring a block close to it's natural limits. It's measured out in 64"'s and you can convert your drill bits to suit math wise. You use the drill bit shank to gap the space between each cyl wallcore. You access this area by knocking out all 6 freeze plugs on the side of the block. 352,360 and 390 blocks commonly fit a 17/64" drill bit shank between the wallcores. 428 and some 406 blocks fit a 13/64" drill bit shank. 427's and some 406's that have 427 wallcores use a 7/64" bit. some 427 blocks have been found to fit a 5/64" bit and those are pretty thick cyl walls. There is also a allen wrench test but I've found the drill bits more accurate. STD 428 blocks found in Tbirds don't have the HD cranksaddle webbing so don't be discouraged about that. That D2 block might be pretty thick so check that one also. Those can be good blocks. some have nodular maincaps. Look for the "ladybug, bump or wart" as they are called ontop of the maincap. You should also see a brinnel indentation on the side of one or more caps if the ladybug is present. If you don't understand any of this let me know and I'll try to explain it better.
Good luck...

Thanks Again. I Will Be Doing That Test. Thanks Scs

The Block I Was Hoping Was A 428 Can Only Fit A 15/64 Drill Bit Shank Between The Cylinder Walls. A 17/64 Is To Big And A 15/64 Is To Small But Just Barely. I Havent Checked The D2 Block Yet.probably Be Next Weekend Before I Am Around Home Again. Thanks Again. Scs
