Has anyone ran the Hughes 237/242 camshaft it has 108 lobe sep 548/555 lift in a pump gas compression 360 engine
 
Depends what engine it is in. 273 yes, 410 stroker No, I have the 234, 238 in my 410 and it idles sweet @ 800rpm and I toodle around in traffic all the time and it is very mild.

Have you used this grind yourself? Is it really lumpy like to much for a street car?

If it's a hydraulic I used that cam, probably the older version in a 340, it was very lumpy. You'll need a loose converter. The engine ran good, it was 11.4-1 with ported Edelbrocks and ran a best of 7.24 @ 94 at 3240# with 4.30 gears. It liked being shifted at 6400.

It wasnt too hairy at all in a 340.
Crackly idle, snappy. It's their 2nd smallest solid iirr. 3.90 gears would be right, 3.73 will work.
Daily driver cam? Ehh... depends...stick car.?Sure.
Automatic, with the right converter yes... but with a cheeeeepo pos its gonna suck imo. Stink, load up at idle...gears will have it accelerating fine once moving...its the rest of the story that's weak.

It depends. what is your PUMP GAS COMPRESSION.
If it is under an honest 10.1 measured compression. NO
If 10 or better compression it would be a decent street cam with a decent 3500 + stall converter and 3.90 gear.
Actually it's a pretty tame cam in my eyes. lol

Always a mystery with Hughes as they don't give you any advertised numbers from which to judge.

FWIW.... I was PM'ing with a friend here who had a Hughes hydraulic cam and had just measured it for .006" lift.... ICA increased 30* between .050" and .006". So if symmetric, then that is 60* between .050" and advertised durations. So pretty slooow down at the lower part of the ramps.

But the OP I think is asking about a solid cam.... so IDK if that same 'slowness' applies.

Lots of things that the OP needs to help us with:
- Trannie type?
- Stall of torque converter if this is an auto trannie?
- Rear gear
- Intended use of the car/engine
- Is this a stock 360, and if so, what year?

I ran that cam in a 9.5 340. #3500 lbs. dart, tunnel ram, 2 340 carbs, 2400 vert,and 3.55s. Best time was 12.8 at 106 mph. With rpm and 750 holley best was 12.96 at 105. Shifted at 6700 with TR and 6300 with rpm.
 
just go to howards catalog or lobe catalog and find cam or lobes to match the hughes
do not see them for whiplash though
looking for .006 for the two whiplash cams
 
In the current catalog
The Hughes code for SBM solids is STL
Their code for a............... FTH, is SEH
A hydraulic roller .................... is SER
No code for solid rollers

So I got no idea what an HEH is;
other than not nearly as fast clearance ramps, as Hughes makes out their cams to be. Having said that tho, I have had two Hughes cams with no complaints; altho they were pretty tame ones,lol.

That's the cam I put in my 408 when I built it but didn't get to run it because when I pulled the valve covers to install the inner springs I found one of the lobes going flat. The only thing I can say is it was lumpy but not radical idle in my 408, for the few minutes I ran it before discovering the problem. As far as any cam being too lumpy for street use, that's all up to personal taste. We do cruise-ins every summer weekend and some of the stuff I see guys drive on a regular basis is insane IMO. But their ok with it

What cam did you replace it with?
 
IMO
a lumpy idle is not an issue.
Rather; the "pumpgas compression 360",is a problem.
The lumpy cam usually points to a late-closing intakes, and a generous amount of overlap.
When coupled with the right cylinder pressure this can be a dynomite combo.
But when coupled with a ,what used to be called "pump gas friendly, compression ratio of 9.0 Scr or say even 9.5, it's a disaster off the line, requiring a higher stall, and un-street-friendly gears, just to get moving. Most times the combo doesn't wake up until well after 3000rpm.
So no, that won't work with 3.23s because 3000 is ~29mph; and who wants to wait that long! Even with 3.91s yur still waiting to ~24mph.
So if it don't spin, it's a total disappointment.
The only choice at that point is a higher stall, to get past that soft zone. And by this time there is no hope of comfortable hi-way cruising, and forget about fuel economy. So what you are left with is a Saturday-Night Cruise-in-and-park combo,with a race car personality.

The partial cure for this is more cylinder pressure, which usually involves more stroke, or more Scr, or really; just an earlier Ica.

Would I run that cam?
Well,
I ran the next bigger 292/292/108DC cam, with a clutch. That combo did not like 3.55s which is what I wanted to run. That cam was out and sold before the first winter. and
I currently run the next smaller Hughes cam, a 230/237/110 hydrocam. For me it is bordeline too big, and I have combo'ed it with 180 psi, a 4.10 equivalent starter gear, and an overdrive.It's a great combo, and has been in my car since summer of 2005.

The problem is the early exhaust opening. It gets terrible fuel economy, and blasts thru a tank of gas in a heartbeat. Even on the hiway in steady-state at 65=2240 and with over 50* of timing.( she likes more). A good portion of the expanding gas energy, goes straight out the exhaust.

Now; above is with a 230/237/110 cam@180psi, in a 367, with a clutch and 3.55s.
Imagine it with a 237/242/108 with 130psi cylinder pressure, an automatic, a 3000 stall and 3.91s, still with a 3.58 stroke. In at 104, the Ica is 66*(same as mine) and the exhaust opens at 104(advertized) same as mine. My overlap is 61*/60 effective. The 237 cam has 70*/64 effective. What this 237cam offers is about a 300 rpm higher power peak, so yeah more absolute power, but the rest is about same as mine. It's gonna need pressure, and it's gonna burn a lotta lotta gas.
