Here's some more exact numbers, regarding CR/DCR, for the info given, using a 8554 head gasket, of 12.7cc and 110 ICL, as well as a 1.11cc crevice volume:

CR of 10.28, DCR 7.89. 10.39 CR and 7.97 DCR w/o the crevice volume.

Depending on the real octane rating, that should be manageable. You can drop it a tenth with a .061 thick FT gasket.

If the ICL is installed to the cam card 106 ( ICL), that rises you to 8.16/8.24 with and w/o crevice vol.

But, if you might of advanced the cam, instead of retarding it 4° (102 ICL), that would put you up to 8.4/8.49

I think you should check the ICL and the IVC, to see where you actually are.

It would help, if we knew the bore & stroke, deck clearance, ICL and head & piston cc or, how much you cut the C8-H's and piston number.

If things aren't to out of wack, you might be able to just retard the cam and put a thicker head gasket on and cure most of your problems.

You have a tough one there.

If your engine is governed, you don't want to get very far out of that range, torque wise. I have Ford FT manuals, from 64 - 75 and it appears Ford never changed much of anything on the FT's. They are rated at 4000 rpm hp wise and 2000 torque wise. Of the three (330,361,391), only the 330 has a different cam. There's no timing given but, the lifts are different on the 330.

I only have 2 suggestions:

1. Get a 361/391 cam

2. Get this Elgin cam, that is  copy of the 390 2v cam and is probably the same as the 360/390 2v PU cam.

E-572-S 1500-4000
Int .433 273 192  113
Exh .436 281 199 111 C7AZ-6250-A Copy

The above cam, should be advanced, 4°- 6°, with your 7.6 CR but, if you have the HD, large snout crank, you can't buy anything to advance it.

You could set it in a milling machine, indicate the hole and move off to your .005. Bore a new hole, to a convenient size, like .500 or the Ford FT size of .516 and bush it to the std size of .453. Then, turn the dist housing .010, to fit w/o binding.

Also, I would take a few thousands of the OD of the dist gear, to make sure it isn't bottoming in the cam gear.

I believe these are the dimensions that you need.

Correct me if I'm wrong but, I believe the "Front Mfg Hole" is the forward, large hole on the bottom of the block.

The nominal dimensions are .58 x 1.619

Is the dist hole also off or just the lower guild hole?

It could be fixed on a mill, now that you know what the error is, by boring and sleeving it.

Thank you, Jay.

I took a look around this morning at different sites for pictures of Crowers and it does look right.

I bought these from Ross, out of his Cobra Engine. He didn't know the make and I would like to ID them, encase I ever need to rebuild them.

There are no marking on them anywhere but, they have 3/4 rollers,  pressure oiled needles and can oil threw the push rods. The hole for the needle bearing oiling is .025.

Richard, are you going to flow them with the 2.3 valves?

Richard, are you selling them?

So, what you basically need, other than the high/low bolt location, is the distance, from the front of FMX case, to the block face?

I have one on a '71, 351W that I could measure. It still bolted to the engine so, my measurement might not be exact.

Ross, I'll take the cam and lifters.

I'll send a Email.

Could we see the sonic map?
