I had cars with both 351W and 351C engines. The stock Cleveland has better
heads than the Windsor, especially the Cleveland 4V. The Windsor has the
bigger mains and better oiling system. Parts for the Windsor ought to be
more plentiful and cheaper.
Here are some of the differences:
Windsor:
5 bolt valve covers
Thermostat on intake
Timing cover is part of the block
Cleveland:
8 bolt valve covers
Thermostat on front of block
External aluminum timing cover
They are both small blocks, but the Cleveland is wider than the Windsor due
to taller deck height (9.123" vs 8.206")
Below is some info I originally got from a website:
351C Engines by VIN Tag Engine Code
Code Engine Type Comment
H 351C-2V Generic low compression 351C, '70-74
M 351C-4V Somewhat Rare, High Compression, '70-71 only

351", 1971 only
R 351C-4V HO Very Rare, Low Compression, Solid Lifters, "High
Output" 1972 only
Q 351C-4V CJ Rare, Low Compression, "Cobra-Jet" May 1971/, '72,
Q 351C-4V CJ Rare, Low Compression, "Cobra-Jet", 1973-74,
decreased performance, see 4V section notes.

Subject: [Bricklin] Cleveland vs Windsor
/I have run across an ad for a '74 351 Cleveland with a AOD transmission
and headers.
I know I have read about some members converting from the Windsor to
Cleveland.
My question is, is this a direct replacement or is the Cleveland
physically larger which might require special attention? I am not
concerned with the AOD portion as I already have replaced my FMX with a
AOD on my stock Windsor. Exactly what identifying marks do I look for to
verify this is a true Cleveland and not just a converted Windsor? Isn't
there a cast in mark on the block?
Thanks,
Don
