Sorry I didn't see this post originally. Do you have any of these cam blanks available?
Can these be finished for the 292 fuel pump lobe?

Paul,
If you want a Cometic head gasket , order it from Mike Kirby, IIRC they are $175.00
Did you call him?
The cylinder head layout is the same. It does have a 4.125" bore though.
MBHD Hank, Somehow I missed this post of yours. I don't have Mike Kirby's number. If you email or PM it to me, I will give him a call. If there were enough people to put up some $$ I would comission Cometic to build an MLS for this application, but at $3K I am not willing to risk the investment on my own at this time. Paul

Bruce Hi Bruce, im doing(5)Chevy Billets right now. Unfortunately, the stock fuel pump arms aren't compatible(metalurgically) with the material roller cams are made out of, an electric fuel pump is going to be the only choice when using one.

I don't see why not. I believe Mike has them in stock. You are better off calling Mike than an email IMO. MBHD

I don't think he's talking about one of his Hank, these are what he is responding to that we were already discussing before you commented. [img]

Yeah, I was referring to your steel cam cores. I want a custom grind. Comp has the profile I want but only lists this as a custom cam. I have not pursued it because I'm a bit behind on projects and won't need it for about a year.
Looks like your cores would be exactlly what the doctor ordred. The lift seems a little low though.

That is just the semi-finished blank in the 3D drawing. They have a full round lobe at this point, the camgrinder finishes it from there and puts their profile on it and makes it a finished product.

There would be a lot less strain on the valve train without all that up and down stuff going on.

Yeah, I want a high lift, short duration roller hydraulic. I think the valve springs will be the major bugaboo. Race springs will work but are overkill for the street. About .600" gross valve lift, RPM limited to about 5252 (where torque=HP). Any suggestions?

Yeah, I know that. Taught Autoshop for many years starting in 1970.
But who cares about all the measuring systems. Good ol' American HP and Torque. That's what we grew up on and understand.
The reason I am limiting the RPM is really more to do with piston speed and valve train stress than anything else.

A pound is a pound, any other unit of measure is a percent( more or less)of the pound. Therefore if you use the correct percent the RPM stays the same 5252.

The significance of 5252 is greatly inflated.

At that RPM, HP and torque are the same.

Horsepower formula; hp= RPM times Torque divided by 5252
Torque formula; torque= 5252 times horsepower divided by RPM
At 5252 rpm, torque and hp are equal (check any hp/torque graphs and see- neat)
They are very important in calculating paint slippage and how much to cut off!

To paraphrase a Garry Moore comic piece called "ode to a tooth" cica 1955 for pistons/valves in our fave motors ..."at least six on bottom an' twelve on top are needed in order to blow things op" Also "cowboys out in nevadda would ask each udder whats the madder?"
It seems all thing old things can be made new. Look up "ode to a tooth" in the encyclopedia brittannica 1955 yearbook (same year Brooklyn Dodgers won the world series).
I gotta sit down-dis is too heavy! Did I stray?

Great, thanks. I've told you all before that there are lots of empty spaces in my knowledge base as well as some spaces filled with stuff that just ain't so. Swiss cheese comes to mind. I must have been out in the sage brush gathering "udders" when that came down the information dirt road, but I knew 5252 was not a Winchester cartridge designation.

Lumps arrived yesterday, Thanx Tom!!
You might hear from the machine shop if they have any questions about the install.
Slow progress so far, but at least it's progress.

Yup,
Not sure if that is a function of USPS and Canda Post, or just Canada Post.
We will do more business in the very near future I'm sure.

Still plugging along with this thing.
Pistons ordered today, Rods have arrived, valves are here too. Head is starting to look very unlike a stock 250 head.
Looking for oil pan for the car (Charlies seems to be a good choice so far).
Cam choice is pretty well done, Toms cam seems to satisfy my tuner and engine builder both. They prefer his cam to the custom grind recommended by Comp Cams.
I need to know what you are doing for accessorie drives. Using a non 250 balancer means bolting a pulley onto the front which of course will not line up with the other pulleys. I do have power steering, but no A/C.
I think I need to get a spare engine in here for mocking up purposes.
