Hey there, so we ended up with a 440, but don't have really any specs on it. Was wondering if anyone could look at these numbers on the end of the camshaft and have an idea of what it potentially was and what the specs would be. Thank you

Maybe if you could have taken an actual GOOD picture that's not frikkin sideways, we might could see it good. Can you at least type out the numbers? I see "275DE I don't fiddle fukkin know". Make things easy if you want help.
 
My bad, calm down bro jeez. Was straight when I posted it, didn't realize it twisted the image.
Yeah idk, looks like 275DEF10 on top VA8860 on bottom

I don't know what "DEF" means. It should be "DEH" which is the Comp dual energy hydraulic. Looks like someone thought it was an F and inscribed it wrong. I agree with PHR's assessment. That's a good grind, too.
 
I think the F was stamped into the core long before the grind number was scribed into it, and poor planning ended up with a situation where the H needed to be where the F already was.

You could well be right.

Thoughts on on how much power a combination could make with that cam, comp roller tip rockers, rpm intake, headers, KB 237 Pistons flat decked, looks like ports were opened up and a compression ratio around 9.6-10.0

With "good" port work, it will easily eclipse 425HP. I think that's a conservative guess.
 
275 deh comp cam big block. Used one in a 383 with some mild head work and about 9.9 compression. It was better than stock and OK but not a big power monger or anything like that. Well, it was a 383 so it was what I expected. Revved well to 5800.
 
How much power you’re trying to make, along with what comprises the rest of the overall combo, would help determine how good or bad of a match that cam is for reaching your goals.

Pretty much the same situation as any other cam.

The farther your goals are from “mild street cruiser”, the more likely it is a different cam wold be a better(more powerful) choice.

Hard to say, how much power actually want to make. First time we've had a big block, thing is going to make close to double anything that car has ever had in it as it sits. But it would be cool to optimize the set if there would be a better camshaft. It will a street car but will see the track every once in a while, kinda drag and drive style of car.
 
You’ll need to come up with some goals/operating parameters.
ET, how much gear and converter you’re planning on running, type of valvetrain, etc.
It’s all part of the puzzle.

Without any set parameters, that cam is as good of a starting point as any.

But, for example, if the target was something like mid-11’s…….another cam would be better…..or even necessary.

If the goal is 13’s, with perhaps an occasional 12…….that cam could possibly be enough(if the rest of the combo is on point).

Some fun reading:
16-17 second 440 combos......
