Just put in another Stipe 280 cam, in a 1926-27 block this time.

This block also, had to be trimmed at the bottom of the lifter bore's, on the block.

I gave them .040 thousandths clearance, and all is well.

So what are you saying? Is the cam lobe too tall, are the lifter flats too thick, is the block cast wrong, is the cam bore mis-aligned in the block???

I wish Stipe would still make the early style 280. I ordered one for my '13, and got a late style cam. When I asked them about it, he said they don't make it anymore.

This is a well known. I believe it is discussed in the installation instructions. It is due to a combination of block, lifter and cam. They fit right in most blocks without the need to remove material.

I just installed one in a 1917. It went right in and the adjustable lifters from Lang's fit without any additional work on the block. The lobes don't scrape on anything. I used the later type front cam bearing.

I had clearance problems installing a Stipe 280 cam in my 13 block. Required milling .040" off the underneath side of the block so the tappet's would not bind against the block.
Happy I discovered the clearance problem before assembling the engine.
Just helped a friend install one in a 26/27 block and it had lot's of clearance.

Adam, as you know, the lift is higher on a 280 so when you use parts that are not stock, you have to compensate for a fit.

The only thing you can do to make it work is to machine the block.

Adjustable lifters are made by Bob's.

While this is the first 25-27 block I have had to machine for the toe, lifter clearance to work, I don't think you could say that most T blocks have room.

They should have at least .040 clearance of free travel.

When did the late style cam start? I have a 14 and a 10.

Late '25.... before august 1925, check your serial number. If before, you have to use the late 26-27 front cam bearing... the others will fit if "new"..... good idea to purchase standard front & middle cam bearings and third bearing if engine if disassembled.

Stipe 280 is a great cam for touring. I have one installed in a '26 engine with a 7 degree advance nylon cam gear...... I'm satisfied !

Bob, the new shorter front cam bearing combined with a longer front lobe on the cam began in april 1924: http://www.mtfca.com/encyclo/doc24.htm
"APR 19 Engine production records, Ford Archives
New camshaft and front bearing in all production."

I think Stipe has included the advance for better mid rpm performance on hills into the cam grind, so extra advance in the cam gear may be to your disadvantage. Advanced cam would help with a reground cam or a worn original.
