As far as I know Crane Cams is out of business. I had recommended their HR216 hydraulic roller camshaft often. A fellow recently contacted me and asked if it would be possible to have a duplicate ground by Bullet Cams. I hadn't thought of doing that.  Good idea.  Thought I'd share the results with you all.

Here's the specs for Crane’s camshaft
Grind # HR-216/325-2S-12; Part # 529541
Hydraulic Roller Cam for a Ford 351C V8
Dual pattern camshaft, asymmetric lobes

Lobe Separation Angle: 112°
Mfg.’s Cam Timing (Indexing): + 1° (advanced)
Intake Lobe Mathematic Centerline: 111° ATDC
Exhaust Lobe Mathematic Centerline: 113° BTDC

Advertised Duration at 0.004: 278°/286°
Duration at 0.006: 272°/280° estimated
Duration at 0.050: 216°/224°
Gross Valve Lift at 1.73:1 Rocker Arm Ratio: 0.562/0.586
Overlap: 52° estimated

There were no exact lobe pattern matches, but we were able to get pretty close.

Order from Bullet Racing Cams
Hydraulic Roller Cam for a Ford 351C V8
Employing Bullet Cams lobe HR271/332 for the intake (asymmetric)
and Bullet Cams lobe HR280/338 for the exhaust (also asymmetric)

Lobe Separation Angle: 112°
Advise indexing the cam: + 8° (advanced)
Intake Lobe Mathematic Centerline: 104° ATDC
Exhaust Lobe Mathematic Centerline: 120° BTDC

Duration at 0.006: 271°/280°
Duration at 0.050: 214°/225°
Gross Valve Lift at 1.73:1 Rocker Arm Ratio: 0.574/0.584
Overlap: 51.5°

I used to advise advancing the timing of the Crane camshaft 6° (or 7° if possible) in order to set the EVO and IVO where I think they should be. This is why I advise having Bullet cams set the timing of this camshaft at +8°.

This cam, advanced as I have recommended, closes the intake valve at 59.5° ABDC which is very early. This requires moderate compression; 9.63:1 static compression (max) equals 8.0:1 dynamic compression.

Hi George,

good to see you post again.



I ran into the Crane Cams problem last year when I wanted to order my cam, inspired by your posts here.

I ended up with Bullet, but also talked to the guys at Crane and Compcams, this is what I got out of it:

"Georg,

          Unfortunately, as of January 1st, Crane Cams is no longer open. However, we can still make the Crane grind as a custom Comp Cams camshaft. It would cost $199.41 for the camshaft and $94.07 for the 832-16 lifters. We can ship internationally but we only use FedEx or UPS. Let me know your address and I will get you a quote on the shipping.

Thanks, Robert

Robert Freund from Crane now works for CompCams and you can still order the Crane grinds as special order from Comp.



Hope this helps and as always: Sorry for my bad english.
