Just another Cam Question

[Mike67]

Has anyone every run the Hughes HER4652BL or one similar? What are your thoughts for a street cam? I'm not worried about vacuum as mine is a non power car...
Specs are .555/.548 246/[email protected] 110LSA
Thanks

Once ran a cam probably slightly milder, was an improvement over the 509 it replaced.

We need some info on your whole package to give advice.

EDDY RPM heads/intake, Dougs 2" headers, 10.3cr w/84cc, ,727/3k, 3.73 w/ 28" tall tire. Will be buying a Fitech FI....
Was talking to a guy that had one in his 68 Baracuda w/4.10 and said he was running 12.3s uncorrected ( I'm at sea level).
I'm just curious if anyone else has run this cam and what their impressions are.
Thanks

I had the non-roller version in my 496" (and then my 526") and loved it. I have no idea what it would have run but it would have been low to mid-11's for sure with my Stage 6's. It was definitely way faster than the previous cam that I ran and that was always in the 11.70's range. I know that no one expects it, but it got great mileage to boot. Almost 14 mpg on the freeway with 4.30's and a 28" tall tire in a 3800 lb. car at 70 mph. Spec-wise the motor was similar. 10.78 compression, 850 DP Holley, M-1 single plane, 2" TTI's. It was kind of crazy because running down the freeway that thing pulled 30" of vacuum. My current combo pulls 1/2 that and gets 1/2 the mileage. It should also go low 10's though, so the drop will be justified.

EDITED: I forgot to add that it pulled almost 15" at idle and had a cranking compression of 210 psi but still ran fine on 93. I ran a slower advance curve (18 initial, 32 total all in at 2500 but started at 1500),and really tight quench (.027 with the Stage VI's) so that helped.

Thanks Brewzer! Do you remember what springs you were using or seat pressure?

Thanks Brewzer! Do you remember what springs you were using or seat pressure?

They were Hughes 1106 springs. Here are their specs:

• Installed Height/Pressure: 1.880"--150#

• Pressure @ .450" lift: 315#

• Pressure @ .500" lift: 325#

• Pressure @ .550" lift: 335#

• Pressure @ .600" lift: 350#

• Pressure @ .650" lift: 365#

• Coil Bind: .680" lift

• Outer Spring ID/OD: 1.130"/1.540"

• Type of Spring: Single w/ damper

I assume since you're using the Roller version of this cam the springs you would be using would be their 1128's:

Never used that cam. Only have used two of the smaller flat tappet hydraulics, and two large solid flat tappet cams from Hughes, but I had good results with all of them.
