Speedmaster cam vs. Comp Cams cam

Aloha. I've been looking for a relatively mild retrofit roller cam for my '68 302. Something like a power band of 1500-5500 rpm. I found Comp Cams 35-421-8 that seems to fit this profile. As has been recommended to me here on VMF, I called Summit, the the guy I talked to recommended the Speedmaster PCE249.1016. The specs on both of them are identical:

Advertised Duration: 270 int./276 exh.
Duration @ 0.050 lift: 218 int./224 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.513 int./0.513 exh.
Lobe Separation (degrees): 110

But the Speedmaster is $199, the Comp Cams is $523 a difference of $324! So, is the Speedmaster a quality piece? Or is the Comp Cams worth the extra money? (If so, please explain what the difference is. )

And I'm open to other cam suggestions that fit my profile.

FYI - rest of the build is AFR 1399 heads, Weiand 8020 intake, Silvolite 3101HC pistons, Summit M2008 500 CFM carb. C-4 Auto trans, 3.25:1 9 inch rear (non-locking).

Hmm, that sounds like a price I would have paid 10-15 years ago. I, for one, have never heard of Speedmaster. Maybe I don't get out enough, LOL! You have some good stuff in what you have now, I'd stick (yes a PUN) with a well known vendor....Oh, and stay roller.

No

Speedmaster = ProComp Electronics = AT Racing World

ProComp has a long history of ripping off other's work, copying it and rebranding it as their own. They were sued by MSD for making near copies of the venerable 6-series ignition box.

They are using the Speedmaster name to hide their history, but aren't being very smart about it.

A recent debacle is where they stated they had hired the former head of engineering from Edelbrock.

Speedmaster said:
Speedmaster is proud to announce the addition of Fredrick (Rick) Roberts PhD as North American Director of Engineering. Rick is well known for serving 28 years as Edelbrock's Director of Engineering and played an integral part in the development of their EFI, Cylinder head and Intake Manifold programs.

Rick then clarified that he was simply consulting for Speedmaster

Rick Roberts said:
Recent announcements by Speedmaster lead one to believe I am a new hire with a lofty position. That is not at all the case! I continue to do business as Roberts Automotive Consultants (RAC) and would be happy to address any engineering needs you have. Speedmaster has been a client of RAC and nothing more. I did not ask for a title but rather simply to provide engineering services as I do with all my clients. RAC specializes in casting design with emphasis on heads and manifolds.

He then scuttled his relationship with them, due to them lying about his position.

Rick Roberts said:
I regret to announce that Speedmaster is no longer a client of Roberts Automotive Consultants. RAC's mission is to develop great parts that people buy because they perform well. Speedmaster's immediate goal, I believe, is to elevate their brand. I am certain I could have provided much needed guidance to improve their products. The potential was there but I am uncomfortable with the way they have characterized our arrangement. It is not at all what my written agreement with them proposed. I can no longer trust how they might choose to use me in the future so a clean break, I think, is best.

You decide if you want to do business with a company that rips off other's IP and lies about their employees. I know that I sure won't.


Back to the cam question, I would talk to Bullet Racing or FlowTech Induction about a cam to suit your build. It'll cost you the same as any other roller cam, but will be tailored to your needs and usage profile.
