[Tigers] Big Valve 260

[James Lindner]

Hi All

Perhaps my engine information might help a bit in the discussion.

I will first say that the engine in my Tiger (B9470033) IS NOT THE ORIGINAL 
ENGINE. I am not even sure if it was sourced from a Tiger; but it is a Ford 
260, so maybe the following info might be some help.

The casting number is C30E-6015B. The casting date is 3D18 (18 Apr 63) and 
it has 3 Freeze plugs.

As for the ORIGINAL engine (1048 E7KL), the info I have received from Norm 
Miller states it was produced on 7 Nov 63 and was taken from the second 
consignment of engines from Ford. Records are available for only 52 engines 
in that group...My Tiger received the 49th. Unfortunately, that original 
engine is long gone, having been switched out for a 289 way back. The owner 
before me returned things to stock specs when the car was restored in 2000. 
Unfortunately, I do not have any info on the origins of the replacement 260.

Jim

Hello All:



Ron's information regarding the engines in the Tiger raises the question as
to the exact configuration of the engines in early Tigers, especially the
intake valve diameter.  His comments got me interested and I dug out my copy
of Monroe's "How To Rebuild Your Small Block Ford".  According to Monroe,
260 blocks with casting numbers C20E-F and C30E-B used intake valves with a
diameter of 1.59 inches.  These were blocks made in '62 & '63, he says.
Later blocks, with casting # C40E-B, manufactured in '64, used 1.67 inch
valves.  Ron raises the possibility that some of the early blocks may have
been used in Tigers.  According to Monroe, the changeover to the C40 blocks
took place in February '63.  Assuming the heads were changed at the same
time (probably a big assumption), the question then becomes, "when were the
Tiger engines purchased?"  Does anyone have an answer?  It seems that I
remember seeing the purchase dates for the different engine batches, but I
cannot remember where.

The other interesting piece of information from Monroe is that the early
blocks (presumably the C20 & C30 numbered) had two freeze plugs on each side
of the block as well as 6-inch engine mount hole spacing.  Later blocks
(after Feb '63) had three freeze plugs and 7-inch spacing.  If anyone has an
early Tiger (vinyl dash?), perhaps they could climb under and take a look at
the engine in their car and tell us how many freeze plugs it has.

None of this is probably definitive, but it might help sorting it all out.
Many thanks to Ron for all his efforts in collecting as much information as
he has.

Cheers,

Tod
