Hi guys... Recently I purchased a engine with a C1AE block, I take apart the cam and had an ECK casting... What's the specs on this cam is a 55'?
The Block is yellow and had a 55 painted at front side! Would be industrial? The C1AE blocks isn't from 55' they are listed 60' I think...

You can link from here to John Mummert's Y-Block site for listings of casting #s etc. Yes, the C1AE block is a late block. I believe the ECK cam is a later than 1957 very mild cam. After 1957, & the intro of the F.E. big block engines, Ford spec's for rebuilds & so on were for a very mild cam, basically a truck cam..

Many Thanks for the reply Paul... Wish I find an Y- Block chart with all the types of cams listed to compare...
Later I take down the Crank and looking for some castings.... I know is not a steel Crank...

You don’t mention if the camshaft you have has a grooved center journal or is cross-drilled. Most ’55 camshafts I’ve checked have the cross-drilled center journals. Here are the specs for two different 1955 ECK camshafts that were reverse engineered.
***************************
Duration @ 0.020”: 233½° In, 239° Ex
Duration @ 0.050”: 197° In, 197° Ex
Lobe lift: 0.253” In, 0.256” Ex
Max valve lift with 1.43 rckrs: 0.366”
As ground lobe centerline: 112½°
*******************************
Adv duration: 231½°I / 235½°E
Duration @ 0.050”: 196°½I / 198°E
Lobe lift: 0.256”I /0 .263”E
Valve lift: .366”I / .376”E before valve adjustment w/1.43:1 rckrs
As ground lobe centers: 112½°

Thanks for the chart. Ford measured their camshaft durations differently back in the day rather than the accustomed methodology being used today. For advertised duration, I typically measure hydraulic camshafts at 0.006” off of the base circle and solid lifter camshafts at 0.020” off of the base circle. Looking at the chart you provided, the specs I posted earlier match up to the 1955 and 1958-1962 camshafts on your list. The ’56 camshaft also appears to be the same but uses 1.54:1 rockers rather than 1.43:1 rockers.

The circular set of numbers at the top of the block at the distributor location would represent the time or shift that the block was cast. The casting date on most later model blocks would be on the right side just below the deck. The casting number or Ford part number on those same blocks is typically on the left side of the block just above the oil filter boss.

Thanks for the reply... Casting is C1AE 60?
The full part number on the block should read something like ‘C1AE-6015-R’.
