Question on 351
I inherited a 351 and I was wondering how to tell whether it is a windsor cleveland or modified. Also I have a C4 tranny, will this bolt right up to the 351? I pulled the motor out of a 81' LTD, and the transmission out of a 82' Granada. My plans are to put this motor into my ford courier and see what kind of damage I can do. If you guys have any tips for me. Let me know.
Thanks
Jason

Question on 351
[updated:LAST EDITED ON 12-Sep-02 AT 11:57 PM (EST)]Hmm...check the motor forums - good info there and probably the most helpful with your situation.
As for the match up - Trucks that came with a 351 came with c-6's as far as I know, so not sure about the fit. Most C-4's were bolted to 302's. If you have both removed, set them side by each and you should be able to tell by looking at it.
Here is some info from an old thread I had posted - I am not taking credit for any info below - the folks who posted know who they are. Hopefully it is useful to you!
"The 351c was made from late 69 to 74. The 351m/400 came out later. The Cleveland block is stronger and the deck height is shorter than a 351m or 400. Thus they take a different intake manifold. The 351C uses a smallblock bellhousing. The 351m/400 use the 385 series ( 429/460 ) bolt pattern. The easiest way to tell the difference between a 351w and a 351M is the location of the thermostat housing. The 351W is on the front of the intake. The 351M/400 is on the block in front of the intake. The 351c,351m and 400 do not have water passages in the intake( ya gotta love the Cleveland for that ) so the intake can be removed without having to drain the coolant. And yes, the 351w has 6 valvecover bolts and the 351m/400 have 8."
"There are some things that you can do, you can have the heads opened up with bigger valves and some good port work, Edelbrock Performer intake and carb. A good cam and valvetrain components, good pistons , and this type of thing. Any motor can make decient power with the right parts inside."
"Secondly there are ways to build "M" motor. The first hurdle is compression. By using various Cleveland pistons you can get the compression ratio you want. I recommend about 9.5:1, no higher."
"A 351w looks like a 302 only 1" taller, the bottom bolt on the thermostat housing is easier to get to on a 351w than a 302.
The Cleveland/M/400 has no water in the intake(IE: the themostat housing is in the block, not the intake).
That is the difference between a 351W & 351c.
Not to mention there are 8 bolts in a Cleveland valve cover and only 6 in a Windsor, which is the same as a 302 valve cover."
