351C small block or big block
« on: February 12, 2011, 09:42:27 PM »
I am confused as to whether the 351C is a small block or a big block. I have a 69 Mach One clone that has a 351C. It needs all the power steering stuff, and I think there is a difference between those components for the big block cars..??? Thanks for any help with this!

Simply stated it's neither. Here is some dimensions on a 351C among other motors.

Ford never used big block/small block terminology thats a chevy thing really. The 351c has the same bell pattern as the 351w so that would make it the same. The heads also will fit on a Windsor block with a special intake so that means it has more in common with the Windsors than any other Ford engine.

Without heads and intake, the 351C is not much different in size than the 351W.  But the heads on the 351C makes it look like a smaller "big block" or maybe a fat small block.  I carried a 351C bare block (with mains) to my neighbors house 2 houses away when I was 16 so the block is not all that heavy.

in 1969 ford made 302, 351 (2)  390 428, and 429. 390 and428 are what ford calls the FE block.  302 and 351 Windsor are Windsor blocks. 302 Boss and 351 C are Cleveland blocks.  429 Boss is 429 boss. The "big blocks" would be 390, 428 and 429.

if you want to get technical it is a small block. A Ford big block would consist of the FE/FT and MEL series engines 332/352/360/361/390/406/410/427/428/429/460/Boss 429/460

I have never heard a 302 BOSS block refered to as a "Cleveland" block, Cleveland style heads - yes, but not the block.  The 302 BOSS is not part of the 335 motors Cleveland series.  The block used in the 302 BOSS was a revised version of the 1968 302 TP (tunnel port) racing block with crossed 4-bolt mains (more like the 427FE motors).  I have always seen the 302 tunnel port motors more closely associated with the other 90 degree, Windsor family of motors.
