the only help i can offer is a phone number for crane cams in austraila, 08 8363 5566, they have an on line cam profile catalog if you can figure out how to use it

you might try deltacam.com They are in Tacoma, Wa.,USA. I have had them repair several of the newer poorly produced comp cams

I found the specs for Y-Blocks ans early FE's and they were very similar.

I also got the flow specs for stock 368 heads so I built a model in DynoSim5 and it worked out to very close to the advertised HP.

I then looked at a more typical modern profile and here is a comparison of the 2. The alternative specs appear in the bottom right. If you can get a grinder to get close to that, it should do the job for you. BTW, the 292 distributor fits, so if you have a loadamatic you can ditch it for the 292 and a Pertronix. You want to go with about 6 initial and 30 in the distributor by 2500.

thanks all ,
Very interesting Hoop 98 !
1956 Motors auto repair manual gives me
intake opens 18 btdc, ex closes 31 atdc, .417 lift ?
already have later 1.54 rockers and distributor
plan to mill heads .050 for more compression
lincolns have a wide valve arrangement,
so they can hit the block with too much lift ...

so I hope to gain more torque and mid range power
and still get reasonable mileage from a big old car

Are you sue that wasn't 13 ATDC?

Here are the Seat to Seat timing on that YBlock cam

Something like 256/266 .430 on a 108 lobe center should work well.
