I've got an older Hughes Camshaft HE3038AL that I'm trying to get the installed centerline. What I do know is .515" intake, .535 exhaust and a 110* LSA. I'ts a great camshaft but I'd really like to degree it correctly.
Appreciate any insight on the correct installed centerline because it is not advertised anywhere that I can find.
 
I have an older one from when Engle made them for Hughes.
.504/.515 110 says install at 104*
When degreed was at 104 on the money starght up l. So got lucky. But had a good multiple keyway chain.
I think is one size smaller than yours.
Was .538/.549 with 1.6 Gold Race Crane Roller Rockers
Memory not what used to be but mine is #2430?
My old machinist was an Engle dist.
He was old school and used plenty of Engle Cams. And pushed them.
Think Howard's now grinds the Hughes camshaft with similar profiles but not exactly due to being property of Engle. From what I understand Engle started the fast rate lift .904 camshaft profiles.

Tell us about the rest of the combo for best recommendation of installation. NA stroker in a 4x4 vs turbo 318 and everything in between would get a different installation in my humble opinion.

Looks like this may be his combination
1.6 Rocker Arm Performance Gains over 1.5 Rocker Arms

The 1.6 ratio may push the pushrods over to where you will need to relieve the heads so they do both hit the openings in head. As well as get a kit from B3 to ger location right on Rockers to valve in the correct location
 
Looks to me that based on the specs in post #3, it's ground with 3* advance, which means the ICL is 107* at "straight up."

You can put it wherever you want though when you degree it - assuming you have the means to adjust cam timing.
 
We did degree it yesterday to see where it came in "straight up".... 106.5* If the Cam "does" have 3* ground into it, I'll just leave it straight up.
But I'd sure like to know for sure.

You'd like to know what? The specs are right there in post #3 (assuming that's your cam). It shows the intake center line is 107*. Looks like your a half a degree off. If that's where you want it, send it.

This right here ^^^^ is the only correct answer so far. Hughes' recommendation may or may not be your best bet depending on the rest of your combination. Perhaps you could enlighten us.

340+.030, 11:5 compression, E85, X heads with Hughes Stage 1 porting, Eddy Air Gap with Holley 750, and MSD ignition. 904, 3400 stall, and 4:11 gearing.

If that's a MEASURED 11:5 then I wouldn't advance it any more than the cam card says. If hoorah up there in post #9 is right about 108 being "straight up" for that cam (no reason he's not right) then 108 is where I'd put it. That's a relatively small cam for that much static compression, but I like it. It'll have big balls on the bottom end and mid range. Like these.

CR is correct. Dave Hughes told me 25 years ago that Cam was "Ideal" for my build with the stage 1 porting. Increased CR and intake are really the only improvements.
 
I am a fan of Daves cams, but buyer beware if you have any headwork performed by them.
 
For a streeter, with a manual trans;
and for me, I like Second gear with 3.55s

I installed that cam in my 367 back in 2004.
**
The ONLY reason to install that cam anywhere but straight up, is if you have a mismatched combo that you are trying to bandaid.
Ie, if your cylinder pressure is too low for alloy heads or too high for irons.
In my engine, each 3 degrees will change the pressure about 4>5psi.
**
I have run that cam form 4 advanced to 2 retarded.
On the street; the midrange doesn't change much.
I run a manual trans and 3.55 gears so, top of Second gear is 6500=77mph, so I don't need any more top-end power. But 30mph in Second gear is 2550, so that's where I want torque. So, I run that cam at +4 to get the Cylinder pressure I need, at an Scr of just 11/1, which in my case is ~185psi. any more than that, and the car gets jumpy when parading at 4mph=550rpm. a jumpiness that with a 750DP and AG I couldn't tune out, and even 550rpm requires the timing be retarded to~5*.
**
This is my third cam, so I about wore out my degree wheel, and the Scr has been adjusted several times in the quest for getting the most out of the engine with 3.55 gears.
**
Engine felt strongest at 195psi.
was weakest at 165, predictably.
Combo is "best" at 185.
**
Car went 93 in the 660, on the only track day this cam ever saw. Four runs, one completed, two missed-shifts, one timer error. that was my morning.
Afternoon was eating trackfood, buying T-shirts and watching the show with my 20yearold son. Nothing broken so, we hit the hiway for home.
**
If you have an automatic with a 3000 stall, who cares about bottom end, the engine is never pulling down there.
**
Honestly, this is way more cam than I needed, I was happier with the next smaller cam, for like 95% of the time, and the smaller cam about doubled my fuel economy, with a more hiway friendly gear. Yeah, that's the one that ran 195psi, lol. For a 367, that was a torque-monster combo.
I've been waiting 20 years for this 3037cam to die so I can go a lil smaller.

All the Hughes stuff has been ground by Howard’s for a long time now.
I purchased mine in 1995.. Maybe Howards was making their cams, but their head porting was another story, they will never see another dime of my money.

Really? I had not knowed dat. Weren't they ground by Bullet before that? I don't think they've ever ground their own cams. I'm a big Howards fan.
 

It was Engle and there was a possum’ match because Engle didn’t like the uber fast lobes.

That’s when they hooked up with Howard’s.
I remember readin on here somewhere Bullet was involved "somehow", but then, there are some here who think the world is flat.
